Interstate 20 marker

Interstate 20 in Texas (abbreviated I-20 or IH-20) is a major east–west Interstate Highway in the Southern United States, running east from a junction with Interstate 10 east of Kent, Texas, through the Dallas-Fort Worth Metroplex to the border with Louisiana near Waskom, Texas. The original distance of Interstate 20 was 647 miles (1,041 km) from I-10 to the Louisiana border, reduced to the current distance of 636 miles (1,024 km) with the rerouting of I-20 in the 1980s and 1990s. I-20 is known as the Ronald Reagan Memorial Highway within the Dallas-Fort Worth Metroplex.

Interstate 20 in Texas was designated in 1959, and was to replace or run parallel to U.S. Route 80. Initial construction began from east to west and as bypass loops around larger cities. By 1967, the highway was complete from the Louisiana border to the western side of Fort Worth on a route to the south of US 80, with slower construction in the lesser populated areas of West Texas concurrent with US 80. In 1971, I-20 was rerouted across the southern side of the Dallas/Fort Worth Metroplex, with the old section through downtown Dallas and Fort Worth being redesignated as Interstate 30. In 1991, the entire concurrent designation of US 80 was removed from the I-10 interchange to Dallas.

I-20 begins at a junction with I-10 in a desolate region of West Texas about 6 miles (10 km) east of the town of Kent. I-20 leaves the interchange with I-10 with a speed limit of 80 until Milemarker 89. Interstate 20 also generally heads to the east-northeast passing by the cities of Odessa and Midland while transitioning from the West Texas desert to the prairie. I-20 runs concurrently with the La Entrada al Pacífico corridor from its junction with US 385 in Odessa to its junction with FM 1788 near Midland International Airport. Near Sweetwater, I-20 begins to head east as it heads towards the city of Abilene. In Abilene, I-20 curves towards the north and transverses the northern part of the city while also forming the northern arc of the loop around the city. I-20 continues heading east from Abilene until the town of Eastland when I-20 takes a more northeasterly route towards Weatherford while transitioning from the West Texas prairie to the central plains of North Texas as the terrain grows hilly. In Weatherford, I-20 again heads back towards the east as it heads towards the Dallas-Fort Worth Metroplex.
