Interstate 40, Transcontinental highway in southern United States
Interstate 40 extends 2,555 miles from Barstow, California to Wilmington, North Carolina, crossing eight states through diverse geographical regions.
Construction of Interstate 40 began in 1957 as part of the Federal-Aid Highway Act, connecting major urban centers across the southern United States.
The roadway follows traditional Native American paths and incorporates segments of Beale's Wagon Road, a significant 19th-century trade route.
The highway functions as a primary transportation artery for commercial trucks and travelers, requiring 43 hours of continuous driving to complete the journey.
The busiest section of Interstate 40 runs through Knoxville, Tennessee, where more than 210,000 vehicles traverse the road each day.
