In the U.S. state of Texas, Interstate 40 (abbreviated I-40) runs west–east through the panhandle in the northwest part of the state. The only large city it passes through is Amarillo, where it meets the north end of Interstate 27.

History

Before the U.S. Route system, this system of interconnected highway from New Mexico to Oklahoma was part of the Texas highway system and a portion of the Ozark Trails which closely paralleled the Chicago, Rock Island and Pacific Railway. When the United States Numbered Highway system was introduced in 1926, Route 66 across the Texas Panhandle was designated along existing roads in the Texas highway network. The entire route was paved by 1938. There have been various realignments, including one in 1959 to allow expansion of the Amarillo Air Force Base.

In 1956, the Interstate Highway Act designated US 66 through Texas as a section of highway eligible for limited access upgrades.

During the next 20 years, most of the highway was upgraded in place, to keep construction costs low. With the limited access of the Interstates, towns on the highway had to be bypassed. Most towns requested to remain as close to the new highway as possible to minimize tourism losses. Bypassed towns included Glenrio, Adrian, Vega, Conway, Groom, Jericho, Alanreed, McLean, and Shamrock. A new routing along the south end of downtown Amarillo was also built, connecting with the already-built expressway leading south from downtown toward Canyon. In 1985, the entire designation of U.S. Route 66 was removed as the entire route had been displaced by Interstate 40.

Route description

At grade intersection on Interstate 40 near mile marker 8 in far west Texas.

I-40 in Texas is one of a few Interstate Highways with at-grade intersections. The westernmost part of I-40 in Texas, near the New Mexico border, lacks the frontage roads typical to Texas freeways, and several driveways for ranches directly intersect the main lanes of I-40, in violation of Interstate standards.

Business routes and old alignments

I-40 has seven business routes in Texas, all of which are old alignments of US 66. A number of other old alignments of US 66 are also present; most are marked on guide signs on I-40.

Business Interstate Highway 40-A (formerly Spur 504) is a Business Spur that runs from I-40 at Glenrio, just east of the New Mexico state line, southwest to the border. In New Mexico, the road forks - the later paved alignment (ca. 1952) has been cut by Interstate 40, and the earlier alignment west to San Jon is now a dirt road that had been paved when it was US 66 prior to 1952 but the paving was later removed by Quay County, NM commissioners due to high maintenance costs and low traffic volumes. The old US 66/I-40 Business Loop through Glenrio was bypassed in 1973 by I-40.[2]

Business Interstate Highway 40-B (formerly Loop 550) is a Business Loop through Adrian. The road was bypassed ca. 1969 by I-40,[3] and carried US 66 until its 1985 decommissioning.[4]

Business Interstate Highway 40-C (formerly Loop 551) is a Business Loop through Vega. The road was bypassed ca. 1973 by I-40,[3] and carried US 66 until its 1985 decommissioning.[5]

Business Interstate Highway 40-D (formerly Loop 552) is a long Business Loop through Amarillo. An older alignment - Loop 279 - carried Business U.S. Highway 66. East of Amarillo, Farm to Market Road 2575 is old US 66, rerouted to today's Business I-40 in 1958[6] by the construction of Amarillo International Airport. Present Business I-40 was bypassed in 1968 by I-40,[3] and carried US 66 until its 1985 decommissioning.[7]

Farm to Market Road 2161 and State Highway 207 carry old US 66 through Conway. The road was bypassed ca. 1966 by I-40,[3] and carried US 66 until its 1985 decommissioning.[8]

Business Interstate Highway 40-F (formerly Loop 554) is a Business Loop through Groom. The road was bypassed ca. 1980 by I-40,[3] and carried US 66 until its 1985 decommissioning.[9]

The short Loop 271, in addition to providing access to Farm to Market Road 291, is old US 66 through Alanreed. The road was bypassed in 1953 by US 66,[10] but the bypass was not upgraded to a freeway until ca. 1982.[3]

Business Interstate Highway 40-H (formerly Loop 555) is a Business Loop through McLean. The road was bypassed ca. 1984 by I-40,[3] and carried US 66 until its 1985 decommissioning.[11]

Business Interstate Highway 40-J (formerly Loop 556) is a Business Loop through Shamrock. The road was bypassed ca. 1973 by I-40,[3] and carried US 66 until its 1985 decommissioning.[12]

Spur 30 is a short route from I-40 just west of the Oklahoma state line southeast to the border. In Oklahoma, the road is unnumbered though Texola, though it picks up Interstate 40 Business at exit 5 to run through Erick. The road was bypassed ca. 1972 by I-40,[3] and carried US 66 until 1976, when it was moved onto I-40 in the area.[13]
