History

Before the U.S. Highway 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
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
Future
In 2015, the Texas Department of Transportation (TxDOT) published the plans for the all new Loop 335 section that will encircle the city of Amarillo.[4] TxDOT has planned multiple multilevel interchanges that intersect with I-40. The first, on the eastside of Amarillo, is a multilevel interchange that will provide access to both directions of I-40 and Loop 335. The second interchange with I-40, however, will be a full stack interchange.[5][6] A new mainlane bridge that will accommodate up to six lanes is also in the works for I-40 near Helium Road, providing easier access to the new freeway.[7] Although construction started in 2016, the project is not expected to be complete until 2022.[8]

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 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 (c. 1952) has been cut by I-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, New Mexico, commissioners due to high maintenance costs and low traffic volumes. Old US 66 (current Bus. I-40-A) through Glenrio was bypassed in 1973 by I-40.[9]
- The short freeway until c. 1982.[10]
