In some locations, low speed limits are the result of lawsuits and resident demands; after holding up the completion of I-35E in St. Paul, Minnesota , for nearly 30 years in the courts, residents along the stretch of the freeway from the southern city limit to downtown successfully lobbied for a 45 mph (70 km/h) speed limit in addition to a prohibition on any vehicle weighing more than 9,000 pounds (4,100 kg) gross vehicle weight . I-93 in Franconia Notch State Park in northern New Hampshire has
10800-401: The collection of tolls, some Interstate routes are toll roads , either because they were grandfathered into the system or because subsequent legislation has allowed for tolling of Interstates in some cases. As of 2022 , about one quarter of all vehicle miles driven in the country used the Interstate Highway System, which has a total length of 48,890 miles (78,680 km). In 2022 and 2023,
10944-507: The construction and improvement of highways. The nation's revenue needs associated with World War I prevented any significant implementation of this policy, which expired in 1921. In December 1918, E. J. Mehren, a civil engineer and the editor of Engineering News-Record , presented his "A Suggested National Highway Policy and Plan" during a gathering of the State Highway Officials and Highway Industries Association at
11088-407: The contiguous United States, primary Interstates—also called main line Interstates or two-digit Interstates—are assigned numbers less than 100. While numerous exceptions do exist, there is a general scheme for numbering Interstates. Primary Interstates are assigned one- or two-digit numbers, while shorter routes (such as spurs, loops, and short connecting roads) are assigned three-digit numbers where
11232-623: The discontinuity, but they have been blocked by local opposition, fearing a loss of business. The Interstate Highway System has been expanded numerous times. The expansions have both created new designations and extended existing designations. For example, I-49 , added to the system in the 1980s as a freeway in Louisiana , was designated as an expansion corridor, and FHWA approved the expanded route north from Lafayette, Louisiana , to Kansas City, Missouri . The freeway exists today as separate completed segments, with segments under construction or in
11376-448: The dissemination of public information. As a result, the 2005 evacuation of New Orleans, Louisiana, prior to Hurricane Katrina ran much more smoothly. According to urban legend , early regulations required that one out of every five miles of the Interstate Highway System must be built straight and flat, so as to be usable by aircraft during times of war. There is no evidence of this rule being included in any Interstate legislation. It
11520-574: The early 1830s, Mormon migrants from northern states and Canada began settling near Independence and areas just north of there. Conflicts over religion and slavery arose between the 'old settlers' (mainly from the South) and the Mormons (mainly from the North). The Mormon War erupted in 1838. By 1839, with the help of an "Extermination Order" by Governor Lilburn Boggs , the old settlers forcibly expelled
11664-578: The east bank of the Mississippi River and identified their settlements as being in le pays des Illinois, "the country of the Illinois". When settlers of French Canadian descent began crossing the Mississippi River to establish settlements such as Ste. Genevieve, they continued to identify their settlements as being in the Illinois Country. At the same time, the French settlements on both sides of
11808-496: The eastern end of the concurrency near Breezewood . Traveling in either direction, I-70 traffic must exit the freeway and use a short stretch of US 30 (which includes a number of roadside services) to rejoin I-70. The interchange was not originally built because of a legacy federal funding rule, since relaxed, which restricted the use of federal funds to improve roads financed with tolls. Solutions have been proposed to eliminate
11952-450: The economy. Not just as a public works measure, but for future growth. Clay's committee proposed a 10-year, $ 100 billion program ($ 1.13 trillion in 2023), which would build 40,000 miles (64,000 km) of divided highways linking all American cities with a population of greater than 50,000. Eisenhower initially preferred a system consisting of toll roads , but Clay convinced Eisenhower that toll roads were not feasible outside of
12096-429: The election of a special convention on secession. This convention voted against secession, but also qualified their support of the Union. In the aftermath of Battle of Fort Sumter Pro-Southern Governor Claiborne F. Jackson ordered the mobilization of several hundred members of the state militia who had gathered in a camp in St. Louis for training. In secret, he also requested Confederate arms and artillery to help take
12240-522: The enactment of the Federal-Aid Highway Act of 1956 . Unlike the earlier United States Numbered Highway System, the interstates were designed to be all freeways, with nationally unified standards for construction and signage. While some older freeways were adopted into the system, most of the routes were completely new. In dense urban areas, the choice of routing destroyed many well-established neighborhoods, often intentionally as part of
12384-492: The existing, largely non-freeway, United States Numbered Highways system. By the late 1930s, planning had expanded to a system of new superhighways. In 1938, President Franklin D. Roosevelt gave Thomas MacDonald , chief at the Bureau of Public Roads, a hand-drawn map of the United States marked with eight superhighway corridors for study. In 1939, Bureau of Public Roads Division of Information chief Herbert S. Fairbank wrote
12528-538: The face of a largely reinforced Union Army. Though regular Confederate troops staged some large-scale raids into Missouri, the fighting in the state for the next three years consisted chiefly of guerrilla warfare . "Citizen soldiers" or insurgents such as Captain William Quantrill , Frank and Jesse James , the Younger brothers , and William T. Anderson made use of quick, small-unit tactics. Pioneered by
12672-426: The federal government, Interstate Highways are owned by the state in which they were built. With few exceptions , all Interstates must meet specific standards , such as having controlled access, physical barriers or median strips between lanes of oncoming traffic, breakdown lanes , avoiding at-grade intersections , no traffic lights , and complying with federal traffic sign specifications. Interstate Highways use
12816-411: The first national road numbering system for cross-country travel. The roads were state-funded and maintained, and there were few national standards for road design. United States Numbered Highways ranged from two-lane country roads to multi-lane freeways. After Dwight D. Eisenhower became president in 1953, his administration developed a proposal for an interstate highway system, eventually resulting in
12960-411: The first three contracts under the new program were signed in Missouri on August 2, 1956. The first contract signed was for upgrading a section of US Route 66 to what is now designated Interstate 44 . On August 13, 1956, work began on US 40 (now I-70) in St. Charles County. Kansas claims that it was the first to start paving after the act was signed. Preliminary construction had taken place before
13104-614: The first time sought to target these funds to the construction of a national road grid of interconnected "primary highways", setting up cooperation among the various state highway planning boards. The Bureau of Public Roads asked the Army to provide a list of roads that it considered necessary for national defense. In 1922, General John J. Pershing , former head of the American Expeditionary Force in Europe during
13248-510: The formation of sinkholes and caves. The southeastern part of the state is known as the Missouri Bootheel region, which is part of the Mississippi Alluvial Plain or Mississippi embayment . This region is the lowest, flattest, warmest, and wettest part of the state. It is also among the poorest, as the economy there is mostly agricultural. It is also the most fertile, with cotton and rice crops predominant. The Bootheel
13392-568: The four-lane expressway was completed from Macon to Hannibal, completing Missouri's portion of the Chicago–Kansas City Expressway. Plans exist to extend I-72 westward from its current terminus in Hannibal to St. Joseph, Missouri along the existing US 36 , but the proposal was shelved for years despite most of the route being a part of the Chicago–Kansas City Expressway . In May 2023, Missouri lawmakers approved
13536-421: The future of the state and nation. In 1860, enslaved African Americans made up less than 10% of the state's population of 1,182,012. In order to control the flooding of farmland and low-lying villages along the Mississippi, the state had completed construction of 140 miles (230 km) of levees along the river by 1860. After the secession of Southern states began in 1861, the Missouri legislature called for
13680-489: The highest speed limits in a given area. Speed limits are determined by individual states. From 1975 to 1986, the maximum speed limit on any highway in the United States was 55 miles per hour (90 km/h), in accordance with federal law. Typically, lower limits are established in Northeastern and coastal states, while higher speed limits are established in inland states west of the Mississippi River . For example,
13824-553: The highly populated coastal regions. In February 1955, Eisenhower forwarded Clay's proposal to Congress. The bill quickly won approval in the Senate, but House Democrats objected to the use of public bonds as the means to finance construction. Eisenhower and the House Democrats agreed to instead finance the system through the Highway Trust Fund , which itself would be funded by a gasoline tax. In June 1956, Eisenhower signed
13968-617: The highway now designated I‑70 and I‑76 opened between Irwin and Carlisle . The Commonwealth of Pennsylvania refers to the turnpike as the Granddaddy of the Pikes, a reference to turnpikes . Milestones in the construction of the Interstate Highway System include: The initial cost estimate for the system was $ 25 billion over 12 years; it ended up costing $ 114 billion (equivalent to $ 425 billion in 2006 or $ 618 billion in 2023 ) and took 35 years. The system
14112-459: The inefficiency of evacuating from southern Louisiana prior to Hurricane Georges ' landfall in September 1998, government officials looked towards contraflow to improve evacuation times. In Savannah, Georgia , and Charleston, South Carolina , in 1999, lanes of I-16 and I-26 were used in a contraflow configuration in anticipation of Hurricane Floyd with mixed results. In 2004, contraflow
14256-429: The institution of slavery . They settled predominantly in 17 counties along the Missouri River , in an area of flatlands that enabled plantation agriculture and became known as " Little Dixie ". The state was rocked by the 1811–12 New Madrid earthquakes . Casualties were few due to the sparse population. In 1821, the former Missouri Territory was admitted as a slave state , under the Missouri Compromise , and with
14400-431: The last two digits match the parent route (thus, I-294 is a loop that connects at both ends to I-94 , while I-787 is a short spur route attached to I-87 ). In the numbering scheme for the primary routes, east–west highways are assigned even numbers and north–south highways are assigned odd numbers. Odd route numbers increase from west to east, and even-numbered routes increase from south to north (to avoid confusion with
14544-549: The late 1840s and 1850s. As a majority were Catholic , they set up their own religious institutions in the state, which had been mostly Protestant . Many settled in cities, creating a regional and then state network of Catholic churches and schools. 19th-century German immigrants created the wine industry along the Missouri River and the beer industry in St. Louis. While many German immigrants were strongly anti-slavery, many Irish immigrants living in cities were pro-slavery, fearing that liberating African-American slaves would create
14688-571: The law." A series of student protests at the University of Missouri against what the protesters viewed as poor response by the administration to racist incidents on campus began in September 2015. On June 7, 2017, the National Association for the Advancement of Colored People issued a warning to prospective African-American travelers to Missouri. This is the first NAACP warning ever covering an entire state. According to
14832-454: The mainline. Some auxiliary highways do not follow these guidelines, however. The Interstate Highway System also extends to Alaska , Hawaii , and Puerto Rico , even though they have no direct land connections to any other states or territories. However, their residents still pay federal fuel and tire taxes. The Interstates in Hawaii, all located on the most populous island of Oahu , carry
14976-753: The maximum speed limit is 75 mph (120 km/h) in northern Maine, varies between 50 and 70 mph (80 and 115 km/h) from southern Maine to New Jersey, and is 50 mph (80 km/h) in New York City and the District of Columbia. Currently, rural speed limits elsewhere generally range from 65 to 80 miles per hour (105 to 130 km/h). Several portions of various highways such as I-10 and I-20 in rural western Texas, I-80 in Nevada between Fernley and Winnemucca (except around Lovelock) and portions of I-15 , I-70 , I-80 , and I-84 in Utah have
15120-439: The middle Mississippi and Ohio river valleys, extending into the southeast and the upper river. The land that became the state of Missouri was part of numerous different territories, possessed changing and often indeterminate borders, and had many different Native American and European names between the 1600s and statehood. For much of the first half of the 1700s, the west bank of the Mississippi River that would become Missouri
15264-427: The musical genres ragtime , Kansas City jazz and St. Louis blues . The well-known Kansas City-style barbecue , and the lesser-known St. Louis-style barbecue , can be found across the state and beyond. Missouri is a major center of beer brewing and has some of the most permissive alcohol laws in the U.S. It is home to Anheuser-Busch , the world's largest beer producer, and produces Missouri wine , especially in
15408-400: The ninth century, built cities and mounds before declining in the 14th century. The Indigenous Osage and Missouria nations inhabited the area when European people arrived in the 17th century. The French incorporated the territory into Louisiana , founding Ste. Genevieve in 1735 and St. Louis in 1764. After a brief period of Spanish rule , the United States acquired Missouri as part of
15552-404: The number of fatalities on the Interstate Highway System amounted to more than 5,000 people annually, with nearly 5,600 fatalities in 2022. The United States government's efforts to construct a national network of highways began on an ad hoc basis with the passage of the Federal Aid Road Act of 1916 , which provided $ 75 million over a five-year period for matching funds to the states for
15696-472: The official Interstate Highway standards . On one- or two-digit Interstates, the mile marker numbering almost always begins at the southern or western state line. If an Interstate originates within a state, the numbering begins from the location where the road begins in the south or west. As with all guidelines for Interstate routes, however, numerous exceptions exist. Missouri Missouri ( / m ɪ ˈ z ʊər i / mih- ZOOR -ee )
15840-557: The old Wabash Railroad from Hannibal, east through Illinois to Champaign, Illinois . The Norfolk Southern Railway operates this railroad route today. In Illinois , I-72 runs for 182 miles (293 km). The portion of I-72 and I-172 from Springfield to Quincy is commonly referred to as the Central Illinois Expressway (CIE). As of 2007, I-72 has one business route ; I-72 Business (I-72 Bus.) in Jacksonville . Near Valley City at mile-marker 42 are
15984-498: The oldest in the world. The Missouri River , after which the state is named, flows through the center and into the Mississippi River , which makes up the eastern border. With over six million residents, it is the 18th-most populous state of the country. The largest urban areas are St. Louis , Kansas City , Springfield , and Columbia . The capital is Jefferson City . Humans have inhabited present-day Missouri for at least 12,000 years. The Mississippian culture , which emerged in
16128-465: The original 1956 plan and several stretches that did not fully conform with federal standards . The construction of the Interstate Highway System cost approximately $ 114 billion (equivalent to $ 618 billion in 2023). The system has continued to expand and grow as additional federal funding has provided for new routes to be added, and many future Interstate Highways are currently either being planned or under construction. Though heavily funded by
16272-498: The people of the Mississippian culture created regional political centers at present-day St. Louis and across the Mississippi River at Cahokia , near present-day Collinsville, Illinois . Their large cities included thousands of individual residences. Still, they are known for their surviving massive earthwork mounds , built for religious, political and social reasons, in platform , ridgetop and conical shapes. Cahokia
16416-399: The phrase "show me" was already in use before the 1890s. Another one states that it is a reference to Missouri miners who were taken to Leadville, Colorado to replace striking workers. Since the new miners were unfamiliar with the mining methods, they required frequent instruction. Other nicknames for Missouri include "The Lead State", "The Bullion State", "The Ozark State", "The Mother of
16560-565: The planning phase between them. In 1966, the FHWA designated the entire Interstate Highway System as part of the larger Pan-American Highway System, and at least two proposed Interstate expansions were initiated to help trade with Canada and Mexico spurred by the North American Free Trade Agreement (NAFTA). Long-term plans for I-69 , which currently exists in several separate completed segments (the largest of which are in Indiana and Texas ),
16704-577: The portion of I-72 and US 36 west of exit 157 to the Hannibal city limits. Route 79 terminated at the foot of the old Mark Twain Memorial Bridge at the corner of Third Street and Mark Twain Avenue. Signs along the four-lane expressway portion of Mark Twain Avenue marked the route as "Future I-72", while signs along what is now Route 79 had I-72 trailblazers to direct drivers to
16848-411: The prefix H . There are three one-digit routes in the state ( H-1 , H-2 , and H-3 ) and one auxiliary route ( H-201 ). These Interstates connect several military and naval bases together, as well as the important communities spread across Oahu, and especially within the urban core of Honolulu . Both Alaska and Puerto Rico also have public highways that receive 90 percent of their funding from
16992-575: The renovation of existing historical buildings in each downtown area. The 2019 announcement of an MLS expansion team in St. Louis is driving even more development in the downtown west area of St. Louis. Kansas City has experienced a boom in population, with new developments such as Three Light apartments being centered in Downtown Kansas City , as well as suburban development in the Northland . Missouri borders eight different states,
17136-614: The return destination of the Lewis and Clark Expedition , which ascended the Missouri River in 1804, to explore the western lands to the Pacific Ocean. For decades, St. Louis was a major supply point for parties of settlers heading west. As many of the early settlers in western Missouri migrated from the Upper South , they brought enslaved African Americans as agricultural laborers, and they desired to continue their culture and
17280-537: The route, without regard to the route number. For instance, I-190 in Massachusetts is labeled north–south, while I-195 in New Jersey is labeled east–west. Some looped Interstate routes use inner–outer directions instead of compass directions, when the use of compass directions would create ambiguity. Due to the large number of these routes, auxiliary route numbers may be repeated in different states along
17424-419: The same numbers, which is generally disallowed under highway administration guidelines. Several two-digit numbers are shared between unconnected road segments at opposite ends of the country for various reasons. Some such highways are incomplete Interstates (such as I-69 and I-74 ) and some just happen to share route designations (such as I-76 , I-84 , I‑86 , I-87 , and I-88 ). Some of these were due to
17568-503: The same roadway are signed as traveling in opposite directions; one such wrong-way concurrency is found between Wytheville and Fort Chiswell , Virginia, where I‑81 north and I‑77 south are equivalent (with that section of road traveling almost due east), as are I‑81 south and I‑77 north. Auxiliary Interstate Highways are circumferential, radial, or spur highways that principally serve urban areas . These types of Interstate Highways are given three-digit route numbers, which consist of
17712-698: The settlement of migrants from the South and its status as a slave state before the Civil War, balanced by the influence of St. Louis. The counties that made up " Little Dixie " were those along the Missouri River in the center of the state, settled by Southern migrants who held the greatest concentration of slaves. In 2005, Missouri received 16,695,000 visitors to its national parks and other recreational areas totaling 101,000 acres (410 km ), giving it $ 7.41 million in annual revenues, 26.6% of its operating expenditures. North of, and in some cases just south of,
17856-497: The state and volunteer regiments for the Union Army. Fighting ensued between Union forces and a combined army of General Price's Missouri State Guard and Confederate troops from Arkansas and Texas under General Ben McCulloch . After winning victories at the battle of Wilson's Creek and the siege of Lexington, Missouri and suffering losses elsewhere, the Confederate forces retreated to Arkansas and later Marshall, Texas , in
18000-434: The state convention was reassembled with most of its members present, save twenty who fled south with Jackson's forces. The convention declared all offices vacant and installed Hamilton Gamble as the new governor of Missouri. President Lincoln's administration immediately recognized Gamble's government as the legal Missouri government. The federal government's decision enabled raising pro-Union militia forces for service within
18144-476: The state is dominated by the Oak-Hickory Central U.S. hardwood forest . Recreational and commercial uses of public forests, including grazing, logging, and mining, increased after World War II. Fishermen, hikers, campers, and others started lobbying to protect forest areas with a "wilderness character". During the 1930s and 1940s, Aldo Leopold , Arthur Carhart and Bob Marshall developed
18288-479: The state legislature into session to call for secession. However, the elected legislative body was split between pro-Union and pro-Confederate. As such, few of the pro-unionist attended the session called in Neosho, and the ordinance of secession was quickly adopted. The Confederacy recognized Missouri secession on October 30, 1861. With the elected governor absent from the capital and the legislators largely dispersed,
18432-495: The state of Missouri, on April 22, 1995, AASHTO approved another renumbering. I-172 was renumbered in its entirety as I-72. The US 36 extension west of Fall Creek was also given the I-72 designation. The Illinois Route 336 (IL 336) expressway was renumbered to I-172 from Fall Creek to Fowler . Prior to September 2000, Mark Twain Avenue (old US 36) was composed of the current Mark Twain Avenue (now Route 79 ) and
18576-455: The state's economy. As the area's first major city, St. Louis expanded greatly after the invention of the steamboat and the increased river trade. Napoleon Bonaparte had gained Louisiana for French ownership from Spain in 1800 under the Treaty of San Ildefonso after it had been a Spanish colony since 1762, but the treaty was kept secret. Louisiana remained nominally under Spanish control until
18720-528: The temporary terminus at Fall Creek, Illinois. When the new Mark Twain Memorial Bridge was completed in September 2000, I-72 was routed over the new bridge, along with US 36. Route 79 was extended along Mark Twain Avenue to terminate at exit 157. The concept of I-72 across Missouri was to create the Chicago–Kansas City Expressway , a rural four-lane highway across northern Missouri and west central Illinois from Cameron, Missouri , at I-35 to Springfield, Illinois , at I-55 . This would provide
18864-626: The third syllable as / i / or / ə / . Any combination of these phonetic realizations may be observed coming from speakers of American English . In British received pronunciation , the preferred variant is / m ɪ ˈ z ʊər i / , with / m ɪ ˈ s ʊər i / being a possible alternative. Donald M. Lance, a professor of English at the University of Missouri , stated that no pronunciation could be declared correct, nor could any be clearly defined as native or outsider, rural or urban, southern or northern, educated or otherwise. Politicians often employ multiple pronunciations, even during
19008-402: The two most common being / m ɪ ˈ z ɜːr i / mih- ZUR -ee and / m ɪ ˈ z ɜːr ə / mih- ZUR -ə . Further pronunciations also exist in Missouri or elsewhere in the United States, involving the realization of the medial consonant as either / z / or / s / ; the vowel in the second syllable as either / ɜːr / or / ʊər / ; and
19152-472: The war, and they are a favorite theme in Branson's self-image . The Progressive Era (1890s to 1920s) saw numerous prominent leaders from Missouri trying to end corruption and modernize politics, government, and society. Joseph "Holy Joe" Folk was a key leader who made a strong appeal to the middle class and rural evangelical Protestants. Folk was elected governor as a progressive reformer and Democrat in
19296-533: The war, both Greater St. Louis and the Kansas City metropolitan area became large centers of industrialization and business. Today the state is divided into 114 counties and the independent city of St. Louis. Missouri has been called the "Mother of the West", the "Cave State", and the "Show Me State". Its culture blends elements of the Midwestern and Southern United States . It is the birthplace of
19440-495: The war, complied by submitting a detailed network of 20,000 miles (32,000 km) of interconnected primary highways—the so-called Pershing Map . A boom in road construction followed throughout the decade of the 1920s, with such projects as the New York parkway system constructed as part of a new national highway system. As automobile traffic increased, planners saw a need for such an interconnected national system to supplement
19584-519: Was a diphtheria epidemic in the area around Springfield, which killed approximately 100 people. Serum was rushed to the area, and medical personnel stopped the epidemic. During the mid-1950s and 1960s, St. Louis and Kansas City suffered deindustrialization and loss of jobs in railroads and manufacturing, as did other Midwestern industrial cities. St. Charles claims to be the site of the first interstate highway project in 1956. Such highway construction made it easy for middle-class residents to leave
19728-438: Was a low-priority project and was shelved. The Missouri Department of Transportation (MoDOT) committed to constructing the four-lane highway as an at-grade expressway only if the five counties served by US 36 east of Macon would contribute half of the $ 100 million (equivalent to $ 136 million in 2023) cost. Road construction to complete the 52.4 miles (84.3 km) between Hannibal and Macon began in 2007. In August 2010,
19872-551: Was employed ahead of Hurricane Charley in the Tampa, Florida area and on the Gulf Coast before the landfall of Hurricane Ivan ; however, evacuation times there were no better than previous evacuation operations. Engineers began to apply lessons learned from the analysis of prior contraflow operations, including limiting exits, removing troopers (to keep traffic flowing instead of having drivers stop for directions), and improving
20016-610: Was mostly uninhabited, something of a no man's land that kept peace between the Illinois on the east bank of the Mississippi River and to the North, and the Osage and Missouri Indians of the lower Missouri Valley. In the early 1700s, French traders and missionaries explored the whole of the Mississippi Valley, and named the region "Louisiana". Around the same time, a different group of French Canadians established five villages on
20160-422: Was proclaimed complete in 1992, but two of the original Interstates— I-95 and I-70 —were not continuous: both of these discontinuities were due to local opposition, which blocked efforts to build the necessary connections to fully complete the system. I-95 was made a continuous freeway in 2018, and thus I-70 remains the only original Interstate with a discontinuity. I-95 was discontinuous in New Jersey because of
20304-494: Was serving as Supreme Commander of Allied Forces in Europe during World War II . In 1954, Eisenhower appointed General Lucius D. Clay to head a committee charged with proposing an interstate highway system plan. Summing up motivations for the construction of such a system, Clay stated, It was evident we needed better highways. We needed them for safety, to accommodate more automobiles. We needed them for defense purposes, if that should ever be necessary. And we needed them for
20448-601: Was the center of a regional trading network that reached from the Great Lakes to the Gulf of Mexico . The civilization declined by 1400 CE, and most descendants left the area long before the arrival of Europeans. St. Louis was at one time known as Mound City by the European Americans because of the numerous surviving prehistoric mounds since lost to urban development. The Mississippian culture left mounds throughout
20592-523: Was the epicenter of the four New Madrid Earthquakes of 1811 and 1812 . Missouri generally has a humid continental climate with cool, sometimes cold, winters and hot, humid, and wet summers. In the southern part of the state, particularly in the Bootheel , the climate becomes humid subtropical . Located in the interior United States, Missouri often experiences extreme temperatures. Without high mountains or oceans nearby to moderate temperature, its climate
20736-541: Was upgraded to a four-lane expressway between US 61 and US 24 at the Rocket Junction (seven miles (11 km)). There are three exits along this expressway: Veterans Road, Shinn Lane (Hannibal Regional Hospital), and US 24 east at the Rocket Junction. Also, an interchange with Route 15 was installed in Shelbina . Due to funding priorities, upgrading US 36 between Macon and Hannibal
