I-20 begins in western [[Reeves County, Texas|Reeves County]] at a fork with I-10. From there, the highway travels east-northeastward through [[Odessa, Texas|Odessa]], [[Midland, Texas|Midland]], and [[Abilene, Texas|Abilene]] before turning eastward toward the [[Dallas–Fort Worth metroplex]]. The [[La Entrada al Pacífico]] corridor runs along I-20 between [[U.S. Route 385|US Route&nbsp;385]] (US&nbsp;385) and [[Farm to Market Road 1788]] (FM&nbsp;1788). Between [[Monahans, Texas|Monahans]] and I-10, I-20 has an {{convert|80|mph|km/h|adj=on}} speed limit.

From the highway's opening in the 1960s through 1977, I-20 originally went through the heart of the metroplex via the [[Dallas–Fort Worth Turnpike]]. This old route is now signed [[Interstate 30|I-30]] (Dallas–Fort Worth Turnpike and from US&nbsp;80/I-30 intersection at Mesquite to [[Downtown Dallas]]), [[U.S. Route 80|US&nbsp;80]] (former stretch between I-635 and [[Terrell, Texas|Terrell]]), and [[Texas State Highway Spur 557|Spur&nbsp;557]] (bypass around Terrell). In 1977, I-20 was rerouted to go through the southern sections of Fort Worth, [[Arlington, Texas|Arlington]], [[Grand Prairie, Texas|Grand Prairie]], [[Dallas]], and [[Mesquite, Texas|Mesquite]]. It split off from the old route initially at I-820 in west Fort Worth the later on at its current junction near [[Aledo, Texas|Aledo]] in [[Parker County, Texas|Parker County]]. It rejoins the old route near Terrell. Part of I-20 in Dallas used to be signed as I-635 and shares the Lyndon B. Johnson Freeway name with the remainder of I-635. Parts on the south side of Fort Worth were originally signed as I-820.<ref>{{Cite map|url=http://dallasfreeways.com/dfwfreeways/old-highway-maps/1973_exxon_dfw_west_large.jpg|title=Dallas–Fort Worth metroplex|publisher=[[Exxon]]}}</ref>

I-20 continues eastward from Terrell, bypassing [[Tyler, Texas|Tyler]], [[Longview, Texas|Longview]], and [[Marshall, Texas|Marshall]] before crossing the Louisiana border near Waskom.
