Interstate 20 Texas
Interstate 20 begins 10 miles east of Kent at the intersection with Interstate 10. From there, the highway travels east northeastward through Odessa, Midland and Abilene before turning eastward towards the Dallas/Fort Worth Metroplex. The La Entrada al Pacifico corridor runs along I-20 between U.S. 385 and FM 1788. Between Monahans and I-10, I-20 has an 80 mph (130 km/h) speed limit, the highest in the United States.

From the highway's opening in the 1960s through 1971, I-20 originally went through the heart of the Metroplex via the Dallas-Fort Worth Turnpike. At that time, I-20 was routed to the southeast west of Fort Worth through the southern sections of Tarrant and Dallas counties. At Mesquite, the highway turned northward, then eastward through Terrell and eastern Texas. This route took the highway over the southern areas of what was once Interstate 820 in Fort Worth and Interstate 635 in Dallas, though I-20 was co-signed with I-635.

That routing of I-20 through the Dallas/Fort Worth area continued until 1987. That year, the highway was rerouted once again, this time from the eastern loop of I-635 and onto a new alignment between Balch Springs and Terrell.

Today I-20 turns to the southeast west of Fort Worth and goes through the southern sections of that city, Arlington, Grand Prairie, Dallas and Mesquite before rejoining its original route at Terrell. Part of I-20 in Dallas is named the Lyndon B. Johnson Freeway.

The original route of I-20 through the heart of the area is now signed Interstate 30 (Dallas-Fort Worth Turnpike), U.S. 80 (former stretch between I-635 and Terrell) and Texas Spur 557 (bypass around Terrell).

Interstate 20 continues eastward from Terrell, bypassing Tyler, Marshall and Longview before crossing the Louisiana border near Waskom.
