They are Minnesota , Wisconsin , Iowa , Illinois , Missouri , Kentucky , Tennessee , Arkansas , Mississippi and Louisiana . It formerly extended north into Canada , serving the provinces of Ontario and Manitoba . The road is designated as both
334-480: A partial cloverleaf interchange with I-14/US 190 and Hood Road. This interchange is located within the boundaries of Fort Cavazos ; the only access to the army base directly from US 190 Business is via Hood Road. The route continues east as Veterans Memorial Boulevard. It intersects State Highway 195 (Fort Hood Road) as the business route exits Fort Cavazos and enters Killeen city limits. The business route passes through downtown Killeen and crosses FM 439 once passing
501-639: A Mississippi River Parkway as an extension of an idea for a recreational river road that had been first put forward by the Missouri Planning Board in 1936. The commission was instrumental not only in the early planning and development of the parkway but also in its construction, promotion, marketing, and development. Now known as the Mississippi River Parkway Commission and headquartered in Minneapolis ,
668-462: A National Scenic Byway and an All-American Road in several states along the route. The term "Great River Road" refers both to a series of roadways and to a larger region inside the US and in each state, used for tourism and historic purposes. Some states have designated or identified regions of state interest along the road and use the roads to encompass those regions. It is divided into two main sections:
835-544: A convoluted alignment, turning southeast on Main Street (still US 136), northeast on 4th Street, northwest on Orleans Avenue, northeast on 7th Street, northwest on Grand Avenue, and northeast on Rand Park Terrace, curving northwest onto the river-hugging Mississippi River Road ( CR X28 and CR X21 ) through Montrose to US 61 . US 61 and US 61 Business lead through Fort Madison to the Fort Madison Bridge and
1002-596: A county road that becomes 10th Street in Keithsburg . Main Street leads west to 4th Street and another county road, ending up on IL 17 west of Joy . Finally, after 2.5 miles (4 km) of travel west on IL 17 to a point north of New Boston , a third north–south county road (designated as CR A in Rock Island County ) takes Great River Road traffic to IL 92 opposite Muscatine, Iowa . The National Route reenters from Muscatine, following IL 92 east through
1169-476: A direct exit to US 61/190 Business (Exit 1C) in downtown Baton Rouge, while southbound motorists must use N. 9th Street (Exit 1G) to connect directly to the business route. US 61/190 Business continues west through downtown until it reaches River Road where it turns right and continues north. Moving north, the business route passes one block to the left of the Louisiana State Capitol and along
1336-1094: A distance. A few miles south of Cameron, US 190 merges and runs concurrently with US 79 north. In Hearne , US 190 splits with US 79 and merges to run concurrently with SH 6 south, entering Brazos County , through Benchley , and into Bryan , that is considered the heart of the Brazos Valley (Southeast Central Texas), and is part of the Bryan-College Station metropolitan area . US 190 splits with SH 6, turning northeast and merging with SH 21 north, entering Kurten , entering Madison County also passing through North Zulch , Cottonwood and into Madisonville , before merging with I-45 south and into Walker County , then entering Huntsville , where US 190 splits heading into Eastern Texas. Continuing east, US 190 enters San Jacinto County , passing north of Oakhurst and Point Blank , crossing Lake Livingston , entering Polk County and into Onalaska . US 190 from
1503-644: A feasibility study. The study, "Parkway for the Mississippi River", was completed by the Bureau of Public Roads (BPR) (predecessor agency to the Federal Highway Administration ) in 1951. The study concluded that a parkway for the Mississippi River would benefit the nation as a whole. However, the report made an important distinction. Because it would be too expensive to build an entirely new parkway, BPR recommended instead that
1670-542: A large mound of sand spanning the width of the river 55 feet below the surface, allowing fresh water and large cargo ships to pass over. Fresh river water flowing from the Mississippi into the Gulf of Mexico does not mix into the salt water immediately. The images from NASA 's MODIS show a large plume of fresh water, which appears as a dark ribbon against the lighter-blue surrounding waters. These images demonstrate that
1837-666: A length of 3,710 miles (5,971 km), making it the fourth longest river in the world after the Nile , Amazon , and Yangtze . When measured by the largest stream source (by water volume), the Ohio River , by extension the Allegheny River , would be the source, and the Mississippi would begin in Pennsylvania . At its source at Lake Itasca , the Mississippi River is about 3 feet (0.91 m) deep. The average depth of

#17327721173852004-615: A long one—full of fits and starts. A late bloomer, the Great River Road was more than 30 years old before it really began to mature. The U.S. House of Representatives ' Committee on Public Lands held hearings in 1939 and 1940 to discuss a bill that would have authorized a feasibility study of the Mississippi River Parkway concept. While popular, the parkway idea was soon overshadowed by World War II . It wasn't until 1949 that Congress approved funding for
2171-478: A natural process known as avulsion or delta switching, the lower Mississippi River has shifted its final course to the mouth of the Gulf of Mexico every thousand years or so. This occurs because the deposits of silt and sediment begin to clog its channel, raising the river's level and causing it to eventually find a steeper, more direct route to the Gulf of Mexico. The abandoned distributaries diminish in volume and form what are known as bayous . This process has, over
2338-412: A new bypass on the south side of Copperas Cove, leaving the original alignment to be made into a business route. The project had been in the planning phases since the 1980s. After delays due to the construction of what would become I-14 to the east of Copperas Cove, the $ 46.5 million bypass opened on January 29, 2015, and the original alignment became Business US 190. Business US 190's western terminus
2505-544: A pilotwheel with the name of the state or province. The over-all logo reads "Canada to Gulf" where the local name would be, and most MRPC publications denote the route as beginning at Lake Itasca in Minnesota and ending in Louisiana. The Great River Road is not a single road but a designated route along connected segments of named and numbered highways and streets maintained by state, county, or local jurisdictions. Until
2672-716: A roadside marker and the joining of two Indian trails. From Junction, US 190 heads east to DeRidder , where it runs concurrently with US 171 south and passes several sites on the National Register of Historic Places , such as the Beauregard Parish Jail , Beauregard Parish Courthouse , and the DeRidder Commercial Historic District . US 190 runs concurrently with US 171 to Ragley , where US 190 parts with US 171 heading east. From Ragley,
2839-661: A sequence of local roads past Meeman-Shelby Forest State Park : Locke Cuba Road, Bluff Road, Riverbluff Road, Herring Hill Road (which is partly unpaved), Pryor Road, and Richardson Landing Road. At Richardsons the route turns east with SR 59 to Covington , then runs north on US 51 . After crossing the Hatchie River on its westernmost bridge, the Great River Road again leaves US 51 at Henning , looping west on SR 87 , north on partly unpaved Crutcher Lake Road (past Fort Pillow State Park ) and Four Mile Lane, and east on SR 19 to rejoin US 51 at Ripley . It leaves US 51 for
3006-566: A short distance. Continuing on a northeastward route, US 190 enters McCulloch County and into Brady . As the closest city to the geographical center of Texas, the city proclaims itself the "True Heart of Texas", "where five major highways meet, making it a major gateway to all regions of the state". US 190 enters Brady from the south merging and running concurrently with north US 377 and US 87 through town, intersecting Farm to Market Road 2028 (FM 2028), FM 2309 , then splitting with US 87 and US 377, before exiting
3173-730: A short piece of US 67 to reach IL 100 , which runs directly along the river for a significant distance before turning inland at Grafton . Rather than cross the Illinois River on the Brussels Ferry , the Great River Road remains with IL 100 alongside the Illinois River, first on the east side to the Hardin Bridge and then on the west side to Kampsville . There it turns west to rejoin the Mississippi River, following IL 96 to north of Hull and former IL 57 to
3340-682: Is 1,151,000 sq mi (2,980,000 km ), of which only about one percent is in Canada. The Mississippi ranks as the world's tenth-largest river by discharge flow, and the largest in North America. Native Americans have lived along the Mississippi River and its tributaries for thousands of years. Many were hunter-gatherers , but some, such as the Mound Builders , formed prolific agricultural and urban civilizations, and some practiced aquaculture . The arrival of Europeans in
3507-794: Is 208,200 cu ft/s (5,900 m /s). Thus, by volume, the main branch of the Mississippi River system at Cairo can be considered to be the Ohio River (and the Allegheny River further upstream), rather than the Middle Mississippi. In addition to the Ohio River , the major tributaries of the Lower Mississippi River are the White River , flowing in at the White River National Wildlife Refuge in east-central Arkansas;
SECTION 20
#17327721173853674-508: Is Business US 190's eastern terminus, where traffic returns to US 190. U.S. Highway 61/190 Business , also called Florida Boulevard and internally designated as U.S. Highway 61-X , is a 10.8 mile (17.4 km) business route that runs along the old alignment of both US 61 and US 190 through downtown Baton Rouge. Although US 190 is signed as a west-to-east route, US 61/190 Business generally does not have directional signage and changes directions multiple times. From southeast to northwest,
3841-403: Is a 3.31 mile (5.33 km) long business route that runs on the old alignment of US 190 through Covington . The road begins at an intersection with US 190 to the west of downtown Covington. The business route continues eastbound into downtown Covington until it reaches Louisiana Highway 21 (LA 21). From here, LA 21 begins to run concurrently with US 190 Business until it returns to US 190 on
4008-575: Is a meandering river in a broad, flat area, only rarely flowing alongside a bluff (as at Vicksburg, Mississippi ). The Mississippi River is known as the Middle Mississippi from the Upper Mississippi River's confluence with the Missouri River at St. Louis, Missouri , for 190 miles (310 km) to its confluence with the Ohio River at Cairo, Illinois . The Middle Mississippi is relatively free-flowing. From St. Louis to
4175-498: Is called the Lower Mississippi River from its confluence with the Ohio River to its mouth at the Gulf of Mexico, a distance of about 1,000 miles (1,600 km). At the confluence of the Ohio and the Middle Mississippi, the long-term mean discharge of the Ohio at Cairo, Illinois is 281,500 cubic feet per second (7,970 cubic meters per second), while the long-term mean discharge of the Mississippi at Thebes, Illinois (just upriver from Cairo)
4342-912: Is controlled and managed as a series of pools created by 26 locks and dams. The Upper Mississippi River is joined by the Minnesota River at Fort Snelling in the Twin Cities ; the St. Croix River near Prescott, Wisconsin ; the Cannon River near Red Wing, Minnesota ; the Zumbro River at Wabasha, Minnesota ; the Black , La Crosse , and Root rivers in La Crosse, Wisconsin ; the Wisconsin River at Prairie du Chien, Wisconsin ;
4509-480: Is followed into Guttenberg . As of 2012, the route through that city leaves US 52 east on Koerner Street, turning north on River Park Drive, west on Broadway Street, north on 2nd Street, west on Kosciusko Street, north on 3rd Street and through the municipal marina to CR X56 . The Great River Road follows the entire length of CR X56 (including former Iowa 340 ) to McGregor , and then continues north on Iowa 76 and CR X52 (partly former Iowa 364 ) to Lansing , where
4676-520: Is largely a multi-thread stream with many bars and islands. From its confluence with the St. Croix River downstream to Dubuque, Iowa , the river is entrenched, with high bedrock bluffs lying on either side. The height of these bluffs decreases to the south of Dubuque, though they are still significant through Savanna, Illinois . This topography contrasts strongly with the Lower Mississippi, which
4843-837: Is likely that bills featuring a congressional I-14 designation will be proposed in the future, as the Fixing America's Surface Transportation Act initially authorized I-14. The Texas Department of Transportation will upgrade US 190 from a two-lane highway to a four-lane divided highway from approximately two miles (3.2 km) south of Heidenheimer, Texas to the Bell County - Milam County line. The $ 77.8 million project will improve driving safety along 7.3 miles of US 190 in central Texas, as new hardened medians will separate each side of traffic. This continues previously completed upgrades along US 190 of two-lane to four-lane highways. The most recent of these improvements were made to
5010-640: Is likely to extend further west and east in central Texas along the US 190 corridor, once adequate funding becomes available. In 2019, Representative Brian Babin (R-TX) introduced legislation in the House of Representatives to extend the I-14 corridor through Odessa , many parts of which would likely follow the US 190 alignment through parts of central Texas. Though the bill was referred to the Congressional Subcommittee on Highways and Transit, it
5177-437: Is located at a signaled intersection with US 190 and Farm to Market Road 2657 (FM 2657). Though signed east–west, the first section of the road runs north-to-northeast toward the city center of Copperas Cove. Turning east after, the road intersects FM 116 , where FM 116 forms a short concurrency with Business US 190 for three blocks. After the concurrency, FM 116 breaks off and continues north towards downtown. Continuing eastward,

5344-593: Is marked entirely along state-maintained highways in Missouri , with more than half along US 61 . Although plates for the National Route are not used in the state, it can be identified based on signage in Illinois. A state alternate route enters the state from Arkansas and follows US 61, including two overlaps with I-55 , all the way to Perryville . The National Route crosses the Mississippi from Illinois on
5511-644: Is part of the National Route, entering from Kentucky at Cairo and leaving at Chester . It follows US 51 off the Cairo Ohio River Bridge through Cairo, and then IL 3 paralleling the river to near Chester. Before entering Chester city limits, the route turns west onto a signed truck bypass that runs closer to the river. It ends by turning southwest onto the Chester Bridge ( IL 150 ) to Missouri. The first section of unbannered route stretches from Chester to near Fall Creek . It begins at
5678-527: Is signed on the Illinois side of the Mississippi north of East Dubuque, although Wisconsin Highway 35 has Great River Road markers all the way to the state line (at IL 35 ). WIS 35 , which hugs Wisconsin 's western border, carries most of the Great River Road in that state from its entrance near East Dubuque, Illinois . The longest separation from WIS 35 is between Tennyson and a point south of Bridgeport , where WIS 35 heads inland through Lancaster and
5845-484: Is taken over by US 61, now heading north towards Natchez and US 190 continues westward towards Opelousas . Although US 61/190 Business has been signed as such since 1960, it did not formally get approval from the American Association of State Highway Officials (AASHO) until 1968. U.S. Highway 190 Business , also known as 21st Avenue or Boston Street and internally known as U.S. Highway 190-X ,
6012-539: Is the only true waterfall on the entire Mississippi River. The water elevation continues to drop steeply as it passes through the gorge carved by the waterfall. After the completion of the St. Anthony Falls Lock and Dam in 1963, the river's head of navigation moved upstream, to the Coon Rapids Dam . However, the Locks were closed in 2015 to control the spread of invasive Asian carp , making Minneapolis once again
6179-618: The American Civil War , the Mississippi's capture by Union forces marked a turning point towards victory , due to the river's strategic importance to the Confederate war effort. Because of the substantial growth of cities and the larger ships and barges that replaced steamboats, the first decades of the 20th century saw the construction of massive engineering works such as levees , locks and dams , often built in combination. A major focus of this work has been to prevent
6346-547: The Amite River . East of Baton Rouge, significant differences from the current alignment are as follows: LA 1032 through Denham Springs; LA 1027 into Walker ; LA 43 and 1040 (Old Baton Rouge Highway) between Albany and Hammond; South Range Road and LA 1067 (Old Covington Highway) between Hammond and the Tangipahoa River ; and Bus.

US 70 leads east into West Memphis , where the National Route historically crossed the Memphis & Arkansas Bridge . The final leg of Arkansas's Great River Road turns north at West Memphis and uses Highway 77 and US 61 north into Missouri. The Great River Road
11523-438: The Great River Road through a nationally coordinated program. BPR recommended "that the selected route shall be improved in a superior manner and that it should be dedicated to recreational purposes as well as to moving traffic". The needed construction and improvements "can be done with regular apportionments under the federal highway act or by the states on their own..." With the Federal Highway Act of 1954, Congress responded to
11690-427: The Great River Road turns west on US 10 across the St. Croix River on the Prescott Drawbridge into Minnesota. On entering Minnesota , the east-side alignment of the Great River Road (here signed as the National Route) follows US 10 west and US 61 south across the Mississippi on the Hastings Bridge into Hastings , where it joins with the west-side alignment. The two sides of the Great River Road combine at
11857-408: The Great River Road uses LA 30 , Government Street, River Road (partly US 61 Business ), State Capitol Drive, Third Street, Spanish Town Road, Fifth Street, and Capitol Access Road ( LA 3045 ) to I-110 . At the Airline Highway interchange on I-110, the National Route comes over the Huey P. Long Bridge ( US 190 ) and turns north to follow I-110 and US 61 into Mississippi. In January 1811, there
12024-712: The Gulf of Mexico by this route, rather than continuing down the Mississippi's current channel past Baton Rouge and New Orleans on a longer route to the Gulf. Although the Red River was once an additional tributary, its water now flows separately into the Gulf of Mexico through the Atchafalaya River. The Mississippi River has the world's fourth-largest drainage basin ("watershed" or "catchment"). The basin covers more than 1,245,000 square miles (3,220,000 km ), including all or parts of 32 U.S. states and two Canadian provinces. The drainage basin empties into
12191-495: The Gulf. The Mississippi River empties into the Gulf of Mexico about 100 miles (160 km) downstream from New Orleans. Measurements of the length of the Mississippi from Lake Itasca to the Gulf of Mexico vary somewhat, but the United States Geological Survey 's number is 2,340 miles (3,766 km). The retention time from Lake Itasca to the Gulf is typically about 90 days; while speed varies along
12358-656: The Heidenheimer area circa 2010. US 190 has six business routes : three in Texas and three in Louisiana. Business U.S. Highway 190-E is a 4.5 mile (7.2 km) long business route that runs through downtown Copperas Cove . In 2010, the Texas Department of Transportation was given approval by the American Association of State Highway and Transportation Officials (AASHTO) to move US 190 to
12525-469: The Illinoian Stage. Timeline of outflow course changes In March 1876, the Mississippi suddenly changed course near the settlement of Reverie, Tennessee , leaving a small part of Tipton County, Tennessee , attached to Arkansas and separated from the rest of Tennessee by the new river channel. Since this event was an avulsion , rather than the effect of incremental erosion and deposition,
12692-578: The Midwestern and eastern U.S. These earthquakes created Reelfoot Lake in Tennessee from the altered landscape near the river. When measured from its traditional source at Lake Itasca , the Mississippi has a length of 2,340 miles (3,766 km). When measured from its longest stream source (most distant source from the sea), Brower's Spring in Montana , the source of the Missouri River , it has
12859-480: The Mississippi River between Saint Paul and Saint Louis is between 9 and 12 feet (2.7–3.7 m) deep, the deepest part being Lake Pepin , which averages 20–32 feet (6–10 m) deep and has a maximum depth of 60 feet (18 m). Between where the Missouri River joins the Mississippi at Saint Louis, Missouri, and Cairo, Illinois, the depth averages 30 feet (9 m). Below Cairo, where the Ohio River joins,
13026-411: The Mississippi River has experienced numerous large and small changes to its main course, as well as additions, deletions, and other changes among its numerous tributaries, and the lower Mississippi River has used different pathways as its main channel to the Gulf of Mexico across the delta region. As Pangaea began to break up about 95 million years ago, North America passed over a volcanic " hotspot " in
13193-469: The Mississippi River near New Madrid, Missouri , between Memphis and St. Louis, is related to an aulacogen (failed rift) that formed at the same time as the Gulf of Mexico. This area is still quite active seismically. Four great earthquakes in 1811 and 1812 , estimated at 8 on the Richter magnitude scale , had tremendous local effects in the then sparsely settled area, and were felt in many other places in
13360-428: The Mississippi River. US 190 (LA) U.S. Route 190 ( US 190 ) is an east–west United States Highway in Louisiana and Texas . Segments of US 190 will be upgraded to Interstate 14 (I-14); the first 24.8-mile (39.9 km) segment was opened on January 26, 2017. The western terminus is at a point where US 190 intersects with I-10 , a few miles east of Bakersfield and 20 mi (32 km) west of
13527-456: The Mississippi near Rock Island, Illinois, diverting it to its present channel farther to the west, the current western border of Illinois. The Hennepin Canal roughly follows the ancient channel of the Mississippi downstream from Rock Island to Hennepin, Illinois . South of Hennepin, to Alton, Illinois , the current Illinois River follows the ancient channel used by the Mississippi River before
13694-532: The Mississippi on the Wakota Bridge and again turns north on US 10 / US 61 , soon entering St. Paul . Shepard Road/Warner Road (mostly County 36 and 37) takes the route west along the St. Paul riverfront to I-35E , where it turns back south and recrosses the Mississippi on the Lexington Bridge . MN 13 takes it to Mendota , at which point it crosses the Minnesota River near its mouth on
13861-465: The Mississippi's watershed drains all or parts of 32 U.S. states and two Canadian provinces between the Rocky and Appalachian mountains. The river either borders or passes through the states of Minnesota , Wisconsin , Iowa , Illinois , Missouri , Kentucky , Tennessee , Arkansas , Mississippi , and Louisiana . The main stem is entirely within the United States; the total drainage basin
14028-642: The Mississippi, becoming County 42 in Wright County . The route jogs north on MN 101 and then turns west on County 39 along the river to Monticello . There it picks up former MN 152 (which has been supplanted by I-94 ), now known as County 75 to St. Cloud . Through that city, the Great River Road follows Clearwater Road and 9th Avenue, crossing the Mississippi into Sauk Rapids on the Sauk Rapids Regional Bridge . County 33 (Benton Drive) leads to Sartell and another river crossing,
14195-854: The Missouri River; the Middle Mississippi, which is downriver from the Missouri to the Ohio River; and the Lower Mississippi , which flows from the Ohio to the Gulf of Mexico. The Upper Mississippi runs from its headwaters to its confluence with the Missouri River at St. Louis, Missouri. It is divided into two sections: The source of the Upper Mississippi branch is traditionally accepted as Lake Itasca , 1,475 feet (450 m) above sea level in Itasca State Park in Clearwater County, Minnesota . The name Itasca
14362-531: The National Route crosses the Black Hawk Bridge ( Iowa 9 ) to Wisconsin. Finally, Iowa 26 carries a state alternate from Lansing north to the Minnesota state line at New Albin . The Great River Road enters Minnesota on MN 26 , connecting to US 61 in La Crescent via a short piece of MN 16 . Except for a detour onto MN 316 , US 61 carries this state alternate route to its junction with
14529-606: The National Route in Hastings . A state alternate route begins in Gretna and crosses the Crescent City Connection ( US 90 Business ) into New Orleans . Tchoupitoulas Street leads along the river to Audubon Park , with Magazine Street , Leake Avenue , and Oak Street continuing from the other side of the park to the city line. In Jefferson Parish , the road becomes River Road (partly LA 611-1 ), from which
14696-584: The Ohio River confluence, the Middle Mississippi falls 220 feet (67 m) over 180 miles (290 km) for an average rate of 1.2 feet per mile (23 cm/km). At its confluence with the Ohio River, the Middle Mississippi is 315 feet (96 m) above sea level. Apart from the Missouri and Meramec rivers of Missouri and the Kaskaskia River of Illinois, no major tributaries enter the Middle Mississippi River. The Mississippi River
14863-607: The Trans-Canada Highway (Highways 1 and 17) to join the Ontario branch at Kenora. The Mississippi River Parkway Planning Commission was formed in 1938 to develop plans for what was to become the Great River Road. Secretary of the Interior Harold Ickes urged the governors of the 10 states along the Mississippi River to form the commission. State planning officials had been developing the concept of
15030-408: The US 190 (Gause Boulevard) interchange and the planning of a new retail center prompted this to be one of many projects to revitalize the area following Hurricane Katrina. Originally scheduled to open in the spring of 2008, multiple instances of severe weather, the threat of Hurricane Gustav , and signage delays pushed the opening of the interchange to late September 2008. Although approved to sign
15197-546: The Upper Mississippi River is the Upper St. Anthony Falls Lock and Dam in Minneapolis. Above the dam, the river's elevation is 799 feet (244 m). Below the dam, the river's elevation is 750 feet (230 m). This 49-foot (15 m) drop is the largest of all the Mississippi River locks and dams. The origin of the dramatic drop is a waterfall preserved adjacent to the lock under an apron of concrete. Saint Anthony Falls
15364-545: The Upper Mississippi is a simple steel culvert, through which the river (locally named "Nicolet Creek") flows north from Lake Nicolet under "Wilderness Road" to the West Arm of Lake Itasca, within Itasca State Park . The earliest bridge across the Mississippi River was built in 1855. It spanned the river in Minneapolis where the current Hennepin Avenue Bridge is located. No highway or railroad tunnels cross under
15531-580: The approach to the Chester Bridge, following IL 150 and the remainder of the truck bypass back to IL 3, which carries the Great River Road all the way to East St. Louis . But instead of continuing along IL 3 through the riverside industrial areas, the route turns east on I-55 / I-70 , north on IL 111 , and back west on I-270 to rejoin IL 3 in Granite City . It soon leaves IL 3 for the last time to follow IL 143 into downtown Alton and then
15698-555: The areas drained by them. Denser salt water from the Gulf of Mexico forms a salt wedge along the river bottom near the mouth of the river, while fresh water flows near the surface. In drought years, with less fresh water to push it out, salt water can travel many miles upstream—64 miles (103 km) in 2022—contaminating drinking water supplies and requiring the use of desalination . The United States Army Corps of Engineers constructed "saltwater sills" or "underwater levees" to contain this in 1988, 1999, 2012, and 2022. This consists of
15865-571: The business route begins at a cloverleaf interchange with both US 190, which continues east toward Hammond , and US 61 , which continues south toward New Orleans . Both mainline routes come together to form a concurrency and continue northward along the Airline Highway , while the continuing road from US 190 becomes the business route. The route continues west through a primarily commercial area and past Baton Rouge Community College before entering downtown Baton Rouge. I-110 northbound has
16032-419: The business route continues to be signed as such. Though more aligned north-to-south, the business route is signed west-to-east. It begins at a T-intersection with US 190 westbound. The entrance to Business US 190 is not accessible from the eastbound lanes of US 190 as a grass median divides the highway. Once on the business route, it turns almost immediately to the right and begins a southeasterly track towards
16199-418: The business route on the boulevard. At either designation, the roads both lost the designation at their respective I-14/US 190 intersections. Business U.S. Highway 190-J is a 2.5 mile (4.0 km) long business route that runs through the town of Heidenheimer along an old alignment of US 190. As US 190 has come to be a major thoroughfare through central Texas, traffic could not handle the two lane road in
16366-567: The center of Jasper intersecting with US 96 . Continuing east, US 190 travels through Holly Springs and enters Newton County , proceeding into Newton . In Newton, US 190 turns south through Bon Wier, and then crosses the Louisiana line. In Newton County, US 190 has been designated one of the routes on the Great Texas Coastal Birding Trail . US 190 crosses the Sabine River and enters
16533-424: The city heading east. US 190 goes through Rochelle , enters San Saba County , through Richland Springs where it intersects FM 45 , the communities Algerita, and Harkeyville, and into San Saba , the birthplace of actor Tommy Lee Jones , and an intersection with SH 16 . Continuing east, US 190 enters Lampasas County , entering Lometa , merging and running concurrently with US 183 south into
16700-432: The city of Lampasas . Splitting from US 183 and continuing east, US 190 runs through Kempner and into the extreme southern corner of Coryell County and Copperas Cove , which is located on the southwestern edge of Fort Cavazos . On the east side of Copperas Cove, a concurrency with I-14 begins. US 190 then traverses through part of Fort Cavazos, into Bell County and Killeen . Being directly adjacent to
16867-511: The commercial district. Continuing eastward, the route passes by Skylar Field Airport and enters Harker Heights, where it intersects both FM 3423 and FM 3219. Approaching US 190, the business route splits: according to the Texas Department of Transportation, the official west-to-east alignment of the route forks to Edwards Drive, while the east-to-west alignment continues on Veterans Memorial Boulevard, though both directions are signed as
17034-505: The commission continues to promote, preserve, and enhance the resources of the Mississippi River Valley and the Great River Road. Representatives of the 10 states and two Canadian provinces serve on the commission's board of directors, and they serve as chairpersons of their state Mississippi River Parkway commissions. But the road from the commission's beginning in 1938 to the success of the Great River Road today has been
17201-604: The country. This is reflected in the Gateway Arch in St. Louis, which was designed to symbolize the opening of the West, and the focus on the " Trans-Mississippi " region in the Trans-Mississippi Exposition . Regional landmarks are often classified in relation to the river, such as "the highest peak east of the Mississippi " or "the oldest city west of the Mississippi". The FCC also uses it as
17368-427: The course of the river, this gives an overall average of around 26 mi (42 km) per day, or 1 mi (1.6 km) per hour. The stream gradient of the entire river is 0.01%, a drop of 450 m over 3,766 km. The Mississippi River discharges at an annual average rate of between 200 and 700 thousand cubic feet per second (6,000 and 20,000 m /s). The Mississippi is the fourteenth largest river in
17535-409: The current alignment generally follows the same route since its extension into Texas in 1935. The only major re-routing was between Deridder and Elton , where the original route followed LA 26 . The portion between Oberlin and Elton was re-routed in 1937 to follow US 165 to Kinder before assuming the current alignment between Deridder and Kinder the following year. Other differences from
17702-436: The current route are as follows: LA 110 through Merryville; LA 3099 into DeRidder; LA 3253 , 1244 , 31 , and 742 between Opelousas and Port Barre ; Old U.S. 190 between Bayou Courtableau and Krotz Springs and between East Krotz Springs, Louisiana Krotz Springs and Lottie ; LA 77 between Livonia and Rosedale ; and LA 76 between Rosedale and Port Allen. In 1937, US 190 took over
17869-466: The delta of the Chippewa River of Wisconsin as it enters the Upper Mississippi, is more than 2 miles (3.2 km) wide. By the time the Upper Mississippi reaches Saint Paul , Minnesota, below Lock and Dam No. 1, it has dropped more than half its original elevation and is 687 feet (209 m) above sea level. From St. Paul to St. Louis, Missouri, the river elevation falls much more slowly and
18036-592: The depth averages 50–100 feet (15–30 m) deep. The deepest part of the river is in New Orleans, where it reaches 200 feet (61 m) deep. The Mississippi River runs through or along 10 states, from Minnesota to Louisiana , and is used to define portions of these states' borders, with Wisconsin , Illinois , Kentucky , Tennessee , and Mississippi along the east side of the river, and Iowa , Missouri , and Arkansas along its west side. Substantial parts of both Minnesota and Louisiana are on either side of
18203-472: The dividing line for broadcast call-signs , which begin with W to the east and K to the west, overlapping in media markets along the river. Due to its size and importance, it has been nicknamed The Mighty Mississippi River or simply The Mighty Mississippi . The Mississippi River can be divided into three sections: the Upper Mississippi , the river from its headwaters to the confluence with
18370-457: The early 1980s, a single Canada-to-Gulf alignment of the Great River Road, serving all ten states, was eligible for special federal funding . The states posted "National Route" plates above the markers on this route and marked their own alternate routes across the river, creating two alignments between New Orleans and Hastings - Point Douglas . Signs marking the National Route are now used only in Illinois and Minnesota. The National Route followed
18537-468: The east side of Covington. The route was approved by AASHO in June 1969, along with the US 190 rerouting. U.S. Highway 190 Business , also known as Fremaux Avenue and internally known as U.S. Highway 190-Y , is a 3.94 mile (6.34 km) long business route that runs on most of the old alignment of US 190 through Slidell . The road begins at the intersection of US 11 (Front Street) and Fremaux Avenue in
18704-473: The entrance of the National Route into Iowa. The National Route returns to US 61 via US 61 Business, splitting to follow CR X62 and Madison Avenue into Burlington . It turns east onto Main Drive through Crapo Park and curves back north on Main Street, which leads to CR X99 (former Iowa 99 ) to north of Toolesboro and CR X61 into Muscatine . After turning onto US 61 Business , the National Route leaves
18871-459: The following segments: More recently, much of the Great River Road, including a portion in every state, has been designated a National Scenic Byway . Few if any signs are present in Louisiana , but the route has been defined by state law. It begins at Venice on the west bank, following LA 23 into Gretna , where the eastern route splits. The western route, historically part of the National Route here, turns west on LA 18 , which it follows all
19038-505: The former US 190, was chosen as the I-10 exit in Slidell. After increased traffic on Gause Road and motorist confusion accessing US 190, the state of Louisiana petitioned AASHO to re-route the highway and create a new business route. At AASHO's June 1971 meeting, this request was approved. US 190 was permanently routed onto the now widened Gause Boulevard and Military Road while US 190 Business
19205-503: The hotspot's activity declined, the crust beneath the embayment region cooled, contracted and subsided to a depth of 2.6 km, and around 80 million years ago the Reelfoot Rift formed a trough that was flooded by the Gulf of Mexico . As sea levels dropped, the Mississippi and other rivers extended their courses into the embayment , which gradually became filled with sediment with the Mississippi River at its center. Through
19372-486: The intersection with LA 22 at Mandeville is multilane divided with controlled access , serving as the primary connector between I-12 and the north end of the Lake Pontchartrain Causeway . The highway's eastern terminus is in the bayous near Slidell, at an intersection with US 90 . This junction was once known as the "White Kitchen" after a restaurant that was once located there. In
19539-634: The last time at Halls , following SR 88 west to near Hales Point , turning north on SR 181 atop a levee to SR 79 near Cottonwood Grove . The route continues north, slightly east of the levee, along Hoecake Road, Robison Bayou Road, Bingham Road, Mooring Road, and SR 21 into Tiptonville . The Great River Road ends its Tennessee stretch by following SR 78 to the state line. The Great River Road's National Route enters Kentucky from Tennessee on KY 94 and runs northeast and east through Hickman . At Cayce it turns north to follow KY 239 , continuing on KY 123 from west of Clinton through Columbus to
19706-402: The last two decades, this number was only 160 million short tons (145 million metric tons) per year. The reduction in sediment transported down the Mississippi River is the result of engineering modification of the Mississippi, Missouri, and Ohio rivers and their tributaries by dams, meander cutoffs , river-training structures, and bank revetments and soil erosion control programs in
19873-420: The left turn from College Drive onto East River Road is no longer permitted due to a reconstruction project. The Great River Road leaves Brainerd to the north on County 3 (former MN 25 ), crossing the Mississippi again at the city limits. North of Merrifield it turns east on County 19, which leads to County 11 and then MN 6 south across the Mississippi and into Crosby . MN 210 leads east to Aitkin , where
20040-502: The lower 10 miles (16 km) of the Kaskaskia River, forming a new Mississippi channel and cutting off the town from the rest of the state. Later flooding destroyed most of the remaining town, including the original State House. Today, the remaining 2,300 acres (930 ha) island and community of 14 residents is known as an enclave of Illinois and is accessible only from the Missouri side. The New Madrid Seismic Zone , along
20207-415: The lower Mississippi from shifting into the channel of the Atchafalaya River and bypassing New Orleans . Since the 20th century, the Mississippi River has also experienced major pollution and environmental problems — most notably elevated nutrient and chemical levels from agricultural runoff, the primary contributor to the Gulf of Mexico dead zone . The word Mississippi itself comes from Misi zipi ,
20374-430: The main cantonment of Fort Cavazos, both Killeen and Copperas Cove depend on the fort and those stationed there. US 190 next intersects and merges with I-35 through Belton and enters Temple , where I-14 ends. The highway then merges and runs concurrently with SH 36 south. Continuing east and south, US 190 passes through Rogers and enters Milam County then Cameron and merges with US 77 south for
20541-495: The main route at Hickman and ends north of Columbus. Portions of the Great River Road in Illinois are signed as the National Route, while other portions lack this banner. National Route signs continue to Mississippi River bridges, with the unbannered alternate routes spurring from these before the crossings. A number of spurs are also signed to parks and other points of interest off the main route. The initial segment in Illinois
20708-416: The majority involved in the revolt. The heads of many of those executed were placed on spikes along the Great River Road. Some sources show the Great River Road continuing south from New Orleans along the east bank on LA 46 and LA 39 to Pointe à la Hache or even further down to Venice. In Mississippi , much of the Great River Road follows US 61 . Between Onward and west of Lula , it runs nearer to
20875-542: The most scenic locations along the river had already been preempted by existing highways, railroads, and towns and cities. The concept of a scenic route rather than a national parkway was adopted. As a result, the Great River Road is not owned by the National Park Service , as is the case with true national parkways, such as the Blue Ridge and Natchez Trace Parkways. Instead, the states have developed
21042-449: The new river channel, contiguous with the adjacent state. Also, due to a meander in the river, a small part of western Kentucky is contiguous with Tennessee but isolated from the rest of its state. Many of the communities along the Mississippi River are listed below; most have either historic significance or cultural lore connecting them to the river. They are sequenced from the source of the river to its end. The road crossing highest on
21209-667: The northeast on 6th Street. A short jog east on US 136 in Hamilton returns the Great River Road to IL 96, which it follows, mostly right along the river, through Nauvoo to Niota . The National Route turns northwest there on IL 9 to the Fort Madison Bridge into Fort Madison, Iowa . IL 96 continues to carry the unbannered route beyond Niota to Lomax , where IL 96 turns inland and the Great River Road follows Carman Road to US 34 near Gulfport . After following US 34 east to near Gladstone , it again turns north onto IL 164 through Oquawka , turning north just east of that village onto
21376-670: The original 1926 plan, US 190 served the purpose of modern-day I-12 as the road around the north side of Lake Pontchartrain to avoid New Orleans . The original western terminus was in Baton Rouge, Louisiana , meeting US 71 at the Baton Rouge– Port Allen ferry across the Mississippi River . US 190 was concurrent with State Route 7 (SR 7, in the pre-1955 Louisiana Highway system ) from Baton Rouge to Covington , then SR 34 from Covington to Slidell, Louisiana . The original eastern terminus of US 190
21543-479: The original route of US 90 from Slidell to the Rigolets Bridge (along current US 11 and LA 433 ) when that highway assumed its current routing into Mississippi . US 190 was given its current eastern terminus at US 90 in the 1940s, following what is now Bus. US 190 (Fremaux Avenue) through Slidell until the 1970s when it was shifted onto Gause Boulevard. In 1951, US 190
21710-647: The other from Lake Itasca into Manitoba . The former followed US 71 to the Fort Frances–International Falls International Bridge , then Highway 71 to Longbow Corners on the Trans-Canada Highway ( Highway 17 ) east of Kenora . Some sources indicate that it continued east on Highway 17 to Dryden or north on Highway 596 to Minaki . The other route followed MN 200 west from Lake Itasca to Zerkel , then ran north on MN 92 to Clearbrook , County 5 and BIA 3 to
21877-620: The past 5,000 years, caused the coastline of south Louisiana to advance toward the Gulf from 15 to 50 miles (24 to 80 km). The currently active delta lobe is called the Birdfoot Delta, after its shape, or the Balize Delta , after La Balize, Louisiana , the first French settlement at the mouth of the Mississippi. The current form of the Mississippi River basin was largely shaped by the Laurentide Ice Sheet of
22044-549: The plume did not mix with the surrounding sea water immediately. Instead, it stayed intact as it flowed through the Gulf of Mexico, into the Straits of Florida , and entered the Gulf Stream . The Mississippi River water rounded the tip of Florida and traveled up the southeast coast to the latitude of Georgia before finally mixing in so thoroughly with the ocean that it could no longer be detected by MODIS. Over geologic time,
22211-575: The primarily residential area. With houses on both sides of the road close to the roadway, a bypass was needed by the mid-2000s. A new four-lane bypass around Heidenheimer looped west around the town, opening in 2010. In October 2010, the AASHTO approved the movement of US 190 to the new bypass. Later in 2010, the Texas Department of Transportation requested AASHTO to also approve the new Business U.S. Highway 190, which had been signed by Texas since US 190's movement. The highway has been subsequently approved and
22378-411: The project be designated a scenic route. The scenic route would consist of existing riverside roads, and new construction would be limited to connecting the existing roads so that a continuous route could be developed. The existing roads would be upgraded to parkway quality. The modified approach would save a great deal of land acquisition and new construction costs. Another consideration was that some of
22545-404: The recommendations of BPR by appropriating planning funds. BPR was authorized to work with each of the states to develop specific criteria for the parkway and to determine one specific route within each state for the Mississippi River Parkway. By the late 1950s, the familiar green-and-white pilot's wheel marker began to spring up on various sections of the designated route. Planning continued through
22712-642: The rest of its path to Iowa, except for the portion through La Grange and Canton , where the Great River Road uses the former alignment of US 61, now Route B. As with Missouri, the National Route in Iowa can mostly be inferred by Illinois signage. On the other hand, the Great River Road uses a number of county and local roads in Iowa. A state alternate route crosses the Des Moines River from Missouri into Keokuk , following US 136 into downtown. It follows
22879-590: The river again into downtown Bemidji, where it turns west on 5th Street. That road continues west and south as County 7 (with yet another bridge), County 3, and County 10, from which the Great River Road again turns west on County 9, which becomes County 40 in Clearwater County and crosses the river yet again.

23380-479: The river, although the Mississippi defines part of the boundary of each of these states. In all of these cases, the middle of the riverbed at the time the borders were established was used as the line to define the borders between adjacent states. In various areas, the river has since shifted, but the state borders have not changed, still following the former bed of the Mississippi River as of their establishment, leaving several small isolated areas of one state across
23547-480: The road intersects northbound FM 1113 and begins to enter the commercial district of Copperas Cove.

27221-448: Was chosen to designate the "true head" of the Mississippi River as a combination of the last four letters of the Latin word for truth ( ver itas ) and the first two letters of the Latin word for head ( ca put ). However, the lake is in turn fed by a number of smaller streams. From its origin at Lake Itasca to St. Louis, Missouri , the waterway's flow is moderated by 43 dams. Fourteen of these dams are located above Minneapolis in
