86-463: Interstate 469 ( I-469 ) is an Interstate Highway in northeastern Indiana . It is an auxiliary route of parent I-69 that also carries portions of US Highway 24 (US 24), US 30 , and US 33 around the urban parts of Fort Wayne . It is 30.83 miles (49.62 km) in length. The Interstate was originally conceived as a bypass for US 24 around the south and east ends of Fort Wayne. Due to heavy traffic on US 30 through

172-535: A concurrency or overlap. For example, I‑75 and I‑85 share the same roadway in Atlanta ; this 7.4-mile (11.9 km) section, called the Downtown Connector , is labeled both I‑75 and I‑85. Concurrencies between Interstate and US Highway numbers are also allowed in accordance with AASHTO policy, as long as the length of the concurrency is reasonable. In rare instances, two highway designations sharing

258-651: A 28-year-old brevet lieutenant colonel, accompanied the trip "through darkest America with truck and tank," as he later described it. Some roads in the West were a "succession of dust, ruts, pits, and holes." As the landmark 1916 law expired, new legislation was passed—the Federal Aid Highway Act of 1921 (Phipps Act). This new road construction initiative once again provided for federal matching funds for road construction and improvement, $ 75 million allocated annually. Moreover, this new legislation for

344-476: A change in the numbering system as a result of a new policy adopted in 1973. Previously, letter-suffixed numbers were used for long spurs off primary routes; for example, western I‑84 was I‑80N, as it went north from I‑80 . The new policy stated, "No new divided numbers (such as I-35W and I-35E , etc.) shall be adopted." The new policy also recommended that existing divided numbers be eliminated as quickly as possible; however, an I-35W and I-35E still exist in

430-425: A mainly wooded area with some industrial properties. After the railroad tracks, SR 930 leaves Coliseum Boulevard at an interchange with Washington Boulevard. The highway heads east-southeast toward New Haven as a four-lane divided highway, passing through commercial properties. The road crosses over another set of Norfolk Southern railroad tracks and turns due east at New Haven Avenue. After New Haven Avenue,

516-428: A majority of sections between the termini of I-469. A 2007 traffic count along I-469 found that only one section of the highway, between Maplecrest Road and I-469's northern terminus, saw traffic numbers close to anywhere along I-69's route around the city, while other sections are much more lightly traveled. John Stafford, who formerly worked for Allen County Plan Commission during planning for I-469, stated in 2008 that

602-589: A numbering scheme in which primary Interstates are assigned one- or two-digit numbers, and shorter routes which branch off of longer ones are assigned three-digit numbers where the last two digits match the parent route. The Interstate Highway System is partially financed through the Highway Trust Fund , which itself is funded by a combination of a federal fuel tax and transfers from the Treasury's general fund. Though federal legislation initially banned

688-491: A proposal for an interstate highway system, eventually resulting in 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,

774-559: A report called Toll Roads and Free Roads , "the first formal description of what became the Interstate Highway System" and, in 1944, the similarly themed Interregional Highways . The Interstate Highway System gained a champion in President Dwight D. Eisenhower, who was influenced by his experiences as a young Army officer crossing the country in the 1919 Motor Transport Corps convoy that drove in part on

860-531: A route along the city's south and east edges. Fort Wayne mayor Ivan Lebamoff supported the east–west expressway, and the route was approved by the state. However, the estimated $ 110 million needed for the project could not be allocated, so the project was scrapped. When the state began looking for a solution to traffic issues on US 24 through Fort Wayne, plans for a bypass began. In large part due to heavy traffic on Coliseum Boulevard, which became known for its commercial properties and issues with bottlenecks ,

946-409: A single digit prefixed to the two-digit number of its parent Interstate Highway. Spur routes deviate from their parent and do not return; these are given an odd first digit. Circumferential and radial loop routes return to the parent, and are given an even first digit. Unlike primary Interstates, three-digit Interstates are signed as either east–west or north–south, depending on the general orientation of

1032-402: A single-track rail line. After the railroad crossing, the road widens to a six-lane undivided highway at Sherman Boulevard. The route then has an intersection with US 27 , and continues passing through commercial properties. After US 27, the highway passes by Glenbrook Square and beings to turns southeast at Clinton Street. After a stoplight at Parnell Avenue, the road passes by

1118-801: A speed limit of 45 mph (70 km/h) because it is a parkway that consists of only one lane per side of the highway. On the other hand, Interstates 15, 80, 84, and 215 in Utah have speed limits as high as 70 mph (115 km/h) within the Wasatch Front , Cedar City , and St. George areas, and I-25 in New Mexico within the Santa Fe and Las Vegas areas along with I-20 in Texas along Odessa and Midland and I-29 in North Dakota along

1204-460: A speed limit of 80 mph (130 km/h). Other Interstates in Idaho, Montana, Oklahoma, South Dakota and Wyoming also have the same high speed limits. In some areas, speed limits on Interstates can be significantly lower in areas where they traverse significantly hazardous areas. The maximum speed limit on I-90 is 50 mph (80 km/h) in downtown Cleveland because of two sharp curves with

1290-474: A suggested limit of 35 mph (55 km/h) in a heavily congested area; I-70 through Wheeling, West Virginia , has a maximum speed limit of 45 mph (70 km/h) through the Wheeling Tunnel and most of downtown Wheeling; and I-68 has a maximum speed limit of 40 mph (65 km/h) through Cumberland, Maryland , because of multiple hazards including sharp curves and narrow lanes through

1376-543: Is also commonly believed the Interstate Highway System was built for the sole purpose of evacuating cities in the event of nuclear warfare . While military motivations were present, the primary motivations were civilian. The numbering scheme for the Interstate Highway System was developed in 1957 by the American Association of State Highway and Transportation Officials (AASHTO). The association's present numbering policy dates back to August 10, 1973. Within

1462-454: Is at an interchange with I-69, US 24 , US 30, and US 33 . The highway heads southeast on Goshen Road from the interchange towards Coliseum Boulevard as a six-lane divided highway, passing between commercial properties and woodland. The route turns east onto Coliseum Boulevard as a four-lane undivided road with a center turn lane, passing through commercial and industrial properties. The highway has an at-grade railroad crossing with

1548-525: Is at the northern terminus of the southern section of State Road 1 (SR 1) and serves the airport via Bluffton Road. After curving northeasterly, I-469 has an interchange with Winchester Road and another with US 27 . At the interchange with US 27, US 33 leaves I-469 heading south concurrently with US 27. The freeway then curves northeasterly, with interchanges at Marion Center Road and Tillman Road. Then, I-469 passes southeast of New Haven , with an interchange at Minnich Road. After

1634-539: Is to have the highway route extend from Tamaulipas , Mexico to Ontario , Canada. The planned I-11 will then bridge the Interstate gap between Phoenix, Arizona and Las Vegas, Nevada , and thus form part of the CANAMEX Corridor (along with I-19 , and portions of I-10 and I-15 ) between Sonora , Mexico and Alberta , Canada. Political opposition from residents canceled many freeway projects around

1720-642: The Allen County War Memorial Coliseum . Then, the road crosses the St. Joseph River and has a traffic light at North Anthony Boulevard. The highway passes between the Purdue University Fort Wayne (PFW) and Ivy Tech Community College campuses, before coming to a traffic light at Crescent Avenue. East of Crescent Avenue, the road becomes a four-lane divided highway and enters mainly residential areas of town until

1806-474: The Dallas–Fort Worth metroplex in Texas, and an I-35W and I-35E that run through Minneapolis and Saint Paul , Minnesota, still exist. Additionally, due to Congressional requirements, three sections of I-69 in southern Texas will be divided into I-69W , I-69E , and I-69C (for Central). AASHTO policy allows dual numbering to provide continuity between major control points. This is referred to as

1892-552: The Federal Aid Highway Act of 1956 into law. Under the act, the federal government would pay for 90 percent of the cost of construction of Interstate Highways. Each Interstate Highway was required to be a freeway with at least four lanes and no at-grade crossings. The publication in 1955 of the General Location of National System of Interstate Highways , informally known as the Yellow Book , mapped out what became

1978-630: The Grand Forks area have higher speed limits of 75 mph (120 km/h). As one of the components of the National Highway System , Interstate Highways improve the mobility of military troops to and from airports, seaports, rail terminals, and other military bases. Interstate Highways also connect to other roads that are a part of the Strategic Highway Network , a system of roads identified as critical to

2064-573: The I-469 . The eastern terminus of SR 930 is at I-469, where US 30's concurrency with I-469 ends, and US 30 continues east along the same road where SR 930 ends. As of 2020, no part of SR 930 is included as a part of the NHS . SR 930 is maintained by the Indiana Department of Transportation (INDOT), like all other state roads in the state. The department tracks

2150-637: The Lincoln Highway was planned to pass through some of the areas that later became SR 930. These sections include the segment of Goshen Road in Fort Wayne now used by SR 930, and the section of what is now SR 930 between Maumee Road and Lincoln Highway in New Haven. The Lincoln Highway was opened in 1915 and passed through downtown Fort Wayne and New Haven. In 1917, Main Market route number 2

2236-465: The Lincoln Highway , the first road across America. He recalled that, "The old convoy had started me thinking about good two-lane highways... the wisdom of broader ribbons across our land." Eisenhower also gained an appreciation of the Reichsautobahn system, the first "national" implementation of modern Germany's Autobahn network, as a necessary component of a national defense system while he

2322-528: The Maumee River and begins to curve to the northwest, entering commercial areas. The next interchange is with the southern terminus of the northern section of SR 37 , after which the route enters residential areas with a small amount of farmland. The highway then curves further west to an interchange at Maplecrest Road. At I-469's northern terminus, it has an interchange with I-69 and an exit-only ramp to Auburn Road; US 24 and US 30 continue to

2408-673: The National Highway System in the United States . The system extends throughout the contiguous United States and has routes in Hawaii , Alaska , and Puerto Rico . In the 20th century, the United States Congress began funding roadways through the Federal Aid Road Act of 1916 , and started an effort to construct a national road grid with the passage of the Federal Aid Highway Act of 1921 . In 1926,

2494-506: The US Department of Defense . The system has also been used to facilitate evacuations in the face of hurricanes and other natural disasters. An option for maximizing traffic throughput on a highway is to reverse the flow of traffic on one side of a divider so that all lanes become outbound lanes. This procedure, known as contraflow lane reversal , has been employed several times for hurricane evacuations. After public outcry regarding

This numbering system usually holds true even if the local direction of the route does not match the compass directions. Numbers divisible by five are intended to be major arteries among the primary routes, carrying traffic long distances. Primary north–south Interstates increase in number from I-5 between Canada and Mexico along

2666-506: The United States Numbered Highway System was established, creating 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

2752-553: The West Coast to I‑95 between Canada and Miami, Florida along the East Coast . Major west–east arterial Interstates increase in number from I-10 between Santa Monica, California , and Jacksonville, Florida , to I-90 between Seattle, Washington , and Boston, Massachusetts , with two exceptions. There are no I-50 and I-60, as routes with those numbers would likely pass through states that currently have US Highways with

2838-454: The 1950s, Coliseum Boulevard was built as a "circumurban" highway, and US 30 was rerouted onto it to bypass the downtown area of Fort Wayne. I-69 was constructed in the 1960s around the west side of the city; its first section opened in October 1962. In 1970, Eli Samaan created a transportation plan for Fort Wayne, including north–south and east–west expressways through the city, along with

2924-576: The Congress Hotel in Chicago. In the plan, Mehren proposed a 50,000-mile (80,000 km) system, consisting of five east–west routes and 10 north–south routes. The system would include two percent of all roads and would pass through every state at a cost of $ 25,000 per mile ($ 16,000/km), providing commercial as well as military transport benefits. In 1919, the US Army sent an expedition across

3010-654: The I-469 designation. A temporary halt to construction occurred in 1991 when crews unearthed a lock that was once used in the Wabash and Erie Canal while constructing the interchange with US 24 east of New Haven. Upon the highway's completion in 1995, its construction was the most expensive in Allen County's history, with a cost of $ 207 million (equivalent to $ 378 million in 2023). In 1998, US 24 and US 30 were rerouted onto I-69 and I-469. In 2005, I-469

3096-515: The Interstate Highway System. Assisting in the planning was Charles Erwin Wilson , who was still head of General Motors when President Eisenhower selected him as Secretary of Defense in January 1953. Some sections of highways that became part of the Interstate Highway System actually began construction earlier. Three states have claimed the title of first Interstate Highway. Missouri claims that

3182-493: The Interstate Highway program. The Interstates of Alaska and Puerto Rico are numbered sequentially in order of funding without regard to the rules on odd and even numbers. They also carry the prefixes A and PR , respectively. However, these highways are signed according to their local designations, not their Interstate Highway numbers. Furthermore, these routes were neither planned according to nor constructed to

3268-577: The Minnich Road exit, the road begins to curve due north along the east side of New Haven. The freeway has an interchange with US 30 / SR 930 at SR 930's eastern terminus; US 30 begins running concurrently with I-469. After the interchange at US 30 is a bridge over Norfolk Southern railroad tracks and an interchange with US 24. This is the eastern end of the concurrency with US 24. I-469 proceeds north, concurrent with both US 24 and US 30. The freeway crosses

Leaving from the Ellipse near the White House on July 7, the Motor Transport Corps convoy needed 62 days to drive 3,200 miles (5,100 km) on the Lincoln Highway to the Presidio of San Francisco along the Golden Gate . The convoy suffered many setbacks and problems on the route, such as poor-quality bridges, broken crankshafts, and engines clogged with desert sand. Dwight Eisenhower , then

3440-778: The United States, including: In addition to cancellations, removals of freeways are planned: The American Association of State Highway and Transportation Officials (AASHTO) has defined a set of standards that all new Interstates must meet unless a waiver from the Federal Highway Administration (FHWA) is obtained. One almost absolute standard is the controlled access nature of the roads. With few exceptions , traffic lights (and cross traffic in general) are limited to toll booths and ramp meters (metered flow control for lane merging during rush hour ). Being freeways , Interstate Highways usually have

3526-481: The act was signed, and paving started September 26, 1956. The state marked its portion of I-70 as the first project in the United States completed under the provisions of the new Federal-Aid Highway Act of 1956. The Pennsylvania Turnpike could also be considered one of the first Interstate Highways, and is nicknamed "Grandfather of the Interstate System". On October 1, 1940, 162 miles (261 km) of

3612-456: The bypass was planned to interchange with I-69. According to Samaan, this helped to accelerate construction when the state decided it would be beneficial to the new employer in the area, stating "I never have seen anything move that fast in my whole life." Construction began in 1988, with the first section built between I-69 and Lafayette Center Road. In June 1989, the US ;24 bypass received

3698-684: The cancellation of the Somerset Freeway . This situation was remedied when the construction of the Pennsylvania Turnpike/Interstate 95 Interchange Project started in 2010 and partially opened on September 22, 2018, which was already enough to fill the gap. However, I-70 remains discontinuous in Pennsylvania , because of the lack of a direct interchange with the Pennsylvania Turnpike at

3784-406: The choice of routing destroyed many well-established neighborhoods, often intentionally as part of a program of " urban renewal ". In the two decades following the 1956 Highway Act, the construction of the freeways displaced one million people, and as a result of the many freeway revolts during this era, several planned Interstates were abandoned or re-routed to avoid urban cores. Construction of

3870-400: The city, support was gained to connect the bypass to I-69 on the city's north end. I-469 was given the name Ronald Reagan Expressway in 2005. I-469 was the most expensive civic project in the history of Allen County , costing over $ 207 million (equivalent to $ 378 million in 2023). As a bypass route, I-469 has been ineffective at helping with north–south traffic along I-69. However,

3956-617: The city. 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

4042-401: 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,

4128-507: 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

4214-407: 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

4300-623: 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

4386-448: 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

4472-496: 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

4558-450: 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

4644-492: 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

4730-426: 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

4816-515: 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

4902-614: 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

4988-556: 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,

5074-553: 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

5160-415: The highway enters the commercial area of New Haven as a four-lane highway with a center turn lane. The route has a traffic light at Lincoln Highway, and SR 930 heads southeast, bypassing downtown New Haven. Southeast of Lincoln Highway, SR 930 is a two-lane highway passing through a mix of commercial and residential properties. The road becomes a four-lane divided highway at Minnich Road, just west of

5246-617: 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

5332-483: The highway was relatively new and would eventually spur growth. Since its construction, I-469 has been ineffective as a north–south bypass around Fort Wayne, in part because its length is 12 miles (19 km) longer than I-69's route around the city. However, officials have stated that heavy truck traffic along Coliseum Boulevard (currently SR 930 ) has almost entirely disappeared, and some have stated that I-469 functions better as an east–west bypass around Fort Wayne. In

5418-490: The idea gained support. The original plans for the bypass were to connect I-69 to US 24 east of Fort Wayne. By 1981, these plans were expanded to connect to I-69 on the city's north side. Samaan stated that he had to convince Governor Otis Bowen in 1978 to expedite construction of the bypass. An additional factor appeared as contracts for the project were being awarded, when General Motors announced construction of an automotive plant in 1984 on Lafayette Center Road, where

5504-459: 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

5590-431: 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

5676-454: 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

5762-753: 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

5848-404: 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

5934-442: 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. Indiana State Road 930 SR 930's western terminus

6020-561: The original Interstate Highway System was proclaimed complete in 1992, despite deviations from 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

6106-656: 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 ),

6192-411: 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

6278-505: The route begins to curve due south toward an intersection with Vance Avenue. After this turn, the route becomes a six-lane divided highway and passes through mainly commercial properties with some woodland. The highway has a traffic light at East State Boulevard and Lake Avenue, before narrowing back to a four-lane divided highway. The road crosses over the Maumee River and the Norfolk Southern Railroad tracks, in

6364-581: The route has served effectively as an east–west bypass around the city, removing heavy truck traffic from passing through Fort Wayne. I-469 begins at I-69 exit 296 and Lafayette Center Road in southwestern Allen County . The freeway heads east as a four-lane freeway, running concurrently with US 33. The highway begins to turn southeast, passing through farmland. The route has a diamond interchange at Lafayette Center Road East and at Indianapolis Road, before turning due east and passing just south of Fort Wayne International Airport . The next interchange

6450-537: 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

6536-419: 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

6622-503: 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

6708-506: The south along I-69. I-469 is maintained by the Indiana Department of Transportation (INDOT). As of 2017, I-469's traffic count was 46,161 vehicles per day, on average between Maplecrest Road and I-469's northern terminus, 34,651 near its interchange with US 30, 14,821 near its interchange with Marion Center Road, and 22,142 between the highway's southern terminus and its interchange with Lafayette Center Road East. By comparison, in 2017, I-69 saw over 60,000 vehicles per day in

6794-488: The traffic volumes along all state highways as a part of its maintenance responsibilities using a metric called average annual daily traffic (AADT), a calculation of the traffic level along a segment of roadway for any average day of the year. In 2024, the lowest traffic levels were 11,078 total vehicles between Green Road and Minnich Road in New Haven. The peak traffic volumes were 47,671 total vehicles between Parnell Avenue and Anthony Boulevard in Fort Wayne. In 1913,

6880-495: 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

6966-481: Was completed by 1956. In 1957, Coliseum Boulevard received the US 30 designation. In 1998, US 24 and US 30 were rerouted onto I-69 and I-469 and the route that became SR 930, including Coliseum Boulevard, was to be decommissioned. INDOT tried to give the route to local control, but Allen County, the city of Fort Wayne, and the City of New Haven did not have funds for the roadway. This led INDOT to commission

7052-551: 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

7138-627: Was given the name Ronald Reagan Expressway, in honor of the former US president. The entire route is in Allen County . Interstate Highway [REDACTED] The Dwight D. Eisenhower National System of Interstate and Defense Highways , commonly known as the Interstate Highway System , or the Eisenhower Interstate System , is a network of controlled-access highways that forms part of

7224-422: 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

7310-494: 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

7396-604: Was the given number to the Lincoln Highway in Indiana. In 1926, US 30 was commissioned to follow SR 2 through Fort Wayne and New Haven. In addition, US 24 was concurrent with US 30 from Washington Boulevard in Fort Wayne and Lincoln Highway in New Haven. In 1948, sections of what would become Coliseum Boulevard were built between US 30/33 (Goshen Road) and Indiana SR 1/427 (Clinton Street) and certified as Indiana SR 324. The rest of Coliseum Boulevard
