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
336-476: 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

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
672-491: 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,

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

Taking advantage of the federal Homestead Acts , pioneer families obtained land claims and began farming and ranching in the Edgewood area during the late 19th and early 20th centuries. Edgewood was founded by a group of southern Santa Fe County residents and landowners. After the incorporation of the town in 1999, large areas of land were annexed. Efforts by the town government to avoid annexing properties whose owners did not wish to be brought within

Both Alaska and Puerto Rico also have public highways that receive 90 percent of their funding from
5964-423: The route from the Arizona border diverts to the south while the freeway turns east by northeast toward Albuquerque . The route departs the Laguna Pueblo, briefly transits the Tohajiilee Indian Reservation (a chapter of the Navajo Nation ), crosses the Rio Puerco , and begins a steep climb to the top of a mesa marked by several small cinder cones overlooking the Rio Grande rift and Albuquerque. From Laguna to
6048-537: 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
6132-419: 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
6216-503: 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
6300-505: The state with the largest exception being a 40-mile (64 km) stretch east of Tucumcari to the Texas border at Glenrio, where traffic was diverted to the old US 66. That section of highway, by this time, became locally and nationally known as "Slaughter Lane" due to tremendous amounts of traffic for a two-lane highway along with rough and narrow paving which led to numerous injury and fatal traffic accidents that reached epidemic numbers in 1968 and 1969. Construction on this section of I-40
6384-454: The town boundaries resulted in a checkerboard pattern of incorporated and unincorporated properties, one of the issues to be resolved in the town's Comprehensive Plan. One controversial annexation greatly enlarged the municipal boundaries and was the source of vigorous public debate. Despite two appeals and one lawsuit, the annexation was upheld. Edgewood is located 33 miles (53 km) east of Albuquerque along Interstate 40 . According to
6468-401: The town was 86.53% White , 0.32% African American , 2.17% Native American , 0.21% Asian , 0.16% Pacific Islander , 8.24% from other races , and 2.38% from two or more races. Hispanic or Latino of any race were 20.34% of the population. There were 676 households, out of which 44.1% had children under the age of 18 living with them, 63.9% were married couples living together, 10.1% had
6552-495: 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
6636-626: The west, no major bypasses had been entirely completed in New Mexico, so traffic was still diverted over the US ;66 routes through each of those cities. In 1970, I-40 was entirely completed through the city of Albuquerque. Other bypasses were completed around various cities through the state, including San Jon (1976) and Tucumcari (1981), Santa Rosa (1972), Moriarty (1973), Grants (1974), and Gallup (1980). Interstate Highway System [REDACTED] The Dwight D. Eisenhower National System of Interstate and Defense Highways , commonly known as
6720-407: Was 36 years. For every 100 females, there were 98.4 males. For every 100 females age 18 and over, there were 94.3 males. The median income for a household in the town was $ 42,500, and the median income for a family was $ 45,952. Males had a median income of $ 33,365 versus $ 24,135 for females. The per capita income for the town was $ 18,146. About 8.4% of families and 10.9% of the population were below
6804-551: 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
6888-501: Was held up by a dispute at San Jon concerning a proposed routing of I-40 bypassing that city to the north by some five miles (8.0 km), which was resolved in November ;1969 when federal and state officials agreed to bring the bypass closer to the city along its northern limits. However, aside from a few small villages, such as Montoya, Newkirk, and Cuervo in the eastern portion of the state and Laguna, Budville, and Cubero to
6972-422: 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
7056-494: 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
