Interstate 40 stretches 177.14 miles across the Texas Panhandle, joining the city of Amarillo with Adrian and Vega to the west and Groom, McLean and Shamrock to the east. Speed limits top out at 75 miles per hour outside Amarillo and at 60 mph across the city.
Approved by the Texas Bureau of Public Roads in 1959, IH 40 replaced historic U.S. 66 west to Barstow, California and east to Oklahoma City, Oklahoma. Seven business loops and spurs are posted for IH 40 in Texas, all along old sections of U.S. 66.
