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
380-476: 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

In 1926, 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
665-589: 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
760-491: 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,
855-626: A proposed routing around the US ;50 corridor in Illinois when the Interstates were first planned. Local pressure pushed the routing closer to the US ;460 corridor because of the cheaper cost and shorter mileage compared to the original routing, but not before construction was started on a short section that is now US 50 between Vincennes, Indiana , and Lawrenceville, Illinois . It

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
1045-734: A short section near I-55/I-70, opened on December 23, 1975. The section from US 460 (later IL 142 ) to US 45 opened on August 7, 1975. I-64 crosses the Wabash River and enters the state of Indiana. It passes Griffin ( State Road 69 , or SR 69; exit 4) and Poseyville ( SR 165 ; exit 12) and also passes under nearby SR 68 (no direct interchange serves SR 68, though one can access said route from either SR 165 or SR 65 ). The Interstate then passes three officially marked exits for Evansville (SR 65, US 41 , and I-69 [formerly designated as I-164 ]) then proceeds through part of

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
1235-801: 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
1330-460: 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
1425-424: A state-retained engineering consultant was for the northern route, but, due in large part to the efforts of a Virginia Senator Mosby Perrow Jr. from Lynchburg, the state changed the location to the southern route in 1959. Despite assurances from the federal government that the route would be decided by the state, Virginia's 1959 decision was overturned in favor of the northern route through Charlottesville. I-64 had

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
1805-501: Is also worth noting that the apparent route of I-64 would have taken it through the southern end of Carlyle Lake which was also under construction at this time. I-64 signs started going up in August 1987 on the US 40 freeway in St. Louis. This change was made in part due to truck drivers deliberately using US 40 to avoid mandatory fines for overweight trucks. On September 9, 2011,

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
2375-756: The Eastern Time Zone (ET; Dubois County ). Between mileposts 60 and 80, I-64 crosses the CT–ET zone boundary five times. With most timezone changes on highways maintained by the Indiana Department of Transportation (INDOT), changes in timezone are not usually marked with any roadside signage. The final crossing into the ET zone at the Perry – Crawford county border, however, is marked with road signage. Between Evansville and New Albany , I-64 intersects

I-64 has concurrencies with I-55 , I-57 , I-75 , I-77 , I-81 , and I-95 . I-64 does not maintain exit number continuity for any of the overlaps, as each of the six north–south routes maintain their exit numbering on their respective overlaps with I-64. Of all the overlaps, I-64 only goes northeast and southwest with I-55 and I-81, while going southeast and northwest with

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

6650-402: 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
6745-431: 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
6840-454: 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
6935-753: 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
7030-404: 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
7125-433: 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. Jefferson County, Illinois Jefferson County
7220-561: 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
7315-662: The other Interstates. In Missouri, the stretch was originally labeled as the Daniel Boone Expressway then only as US 40, and, as such, is still known to some locals in Greater St. Louis as Highway 40, even though the road has been designated as both I-64 and US 40 since 1988. This road is also the southernmost portion of the Avenue of the Saints . An interchange at Highway N in O'Fallon opened on December 13, 2004. This interchange also accommodates
7410-656: 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 ),
7505-428: The population. In terms of ancestry, 24.3% were German , 15.8% were Irish , 13.6% were English , and 10.2% were American . Of the 15,365 households, 30.1% had children under the age of 18 living with them, 50.0% were married couples living together, 11.4% had a female householder with no husband present, 34.0% were non-families, and 29.1% of all households were made up of individuals. The average household size
7600-411: 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
7695-500: The rest of suburban St. Clair County , the freeway heads southeast through rural Southern Illinois . Shortly after passing MidAmerica St. Louis Airport at exit 23, I-64 enters Clinton County and then Washington County . After providing access to towns such as Carlyle , Breese , Nashville , and Centralia , the freeway overlaps I-57 through the Mount Vernon area for approximately five miles (8.0 km). East of Mount Vernon in Illinois, services along I-64 are slim to none. It
7790-620: The route forms a fishhook around Norfolk. I-264 intersects the beltway, providing access to other parts of Norfolk and Chesapeake and extending east to the Oceanfront. Access to the Oceanfront area is accomplished from I-64 via a portion of I-264, a roadway originally built as the Virginia Beach Expressway , funded by tolls to retire revenue bonds . Elements of I-64, such as the Sherman Minton bridge over
7885-657: The route is the nine-mile (14 km) stretch from the SR ;65 exit to mikemarker 26, one mile (1.6 km) east of US 41. There are many points along the route where the two halves of the highway are nearly 500 feet (150 m) apart, especially around the Hoosier National Forest and points to the east. In addition, there are several points, especially in the very sharp valleys along its route in Dubois, Perry, Crawford, and Harrison counties, where
7980-537: 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
8075-419: 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
8170-503: 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
8265-483: The scenic Hoosier National Forest , with exits leading to Dale and Huntingburg ( US 231 ; exit 57); Santa Claus and Ferdinand ( SR 162 ; exit 63); French Lick and Tell City ( SR 37 ; exit 79); and Indiana's first state capital, Corydon ( SR 135 ; exit 105). Near milepost 61, there is a time change from the Central Time Zone (CT; Spencer County ) to
8360-441: The state near Ashland at Catlettsburg . It overlaps I-75 as it makes an arc around the northeast of Lexington's urban core, with the exit numbers for I-75 used for the concurrent portion. The two Interstates separate a few miles east of downtown Lexington. I-64 travels for 188.75 miles (303.76 km) within the state of West Virginia , passing by the major cities of Huntington , Beckley , and Lewisburg and directly through
8455-509: The tie-in of the Route ;364 freeway to I-64. In April 2007, construction started to rebuild 10.5 miles (16.9 km) of I-64 in St. Louis from Spoede Road to Kingshighway. This project included repaving the entire road, rebuilding the overpasses and interchanges , adding a fourth lane between Spoede Road and I-170 , and connecting I-64 to I-170 in all directions. Construction resulted in
8550-495: 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
8645-470: Was 2.38 and the average family size was 2.92. The median age was 40.6 years. The median income for a household in the county was $ 41,161 and the median income for a family was $ 51,262. Males had a median income of $ 41,193 versus $ 29,645 for females. The per capita income for the county was $ 21,370. About 12.4% of families and 17.1% of the population were below the poverty line , including 24.8% of those under age 18 and 10.7% of those age 65 or over. In 2015
8740-551: 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
8835-422: 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
8930-547: 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
9025-533: Was therefore retrograde, from the west toward the interior of the State. In 1814, Andrew Moore departed with his eight-year-old son for Jordan's settlement, a journey from which he never returned. A skull that was believed to have been Moore's was found several years later about two miles from his cabin. Jordan's Settlement, also called Jordan's Fort, was southeast of modern Thompsonville , Illinois , about twenty miles south of Moore's cabin. This episode occurred during
