Interstate 20 in Texas

I-20 begins its eastward journey 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 mph (130 km/h) until mile marker 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.

I-20 in southern Fort Worth

I-20 interchanges with I-30 west of Fort Worth with I-30 heading east and I-20 to the southeast. I-20 heads back towards the east when it interchanges with Interstate 820. I-20 forms the southern arc of the complete loop around the city of Fort Worth, and serves as the southernmost west–east freeway in the Dallas-Fort Worth Metroplex. Interchanging with I-35W south of downtown Fort Worth, I-20 heads east towards Dallas passing through Arlington, where it is also known as the Ronald Reagan Memorial Highway.[4] From Arlington, I-20 passes into Dallas County at Grand Prairie and heads east in to Dallas, interchanging with I-35E south of downtown and I-45 shortly after. I-20 intersects with I-635 (where it completes a three-quarter loop around the city) on Dallas' southeast side before heading east towards East Texas. The interstate varies from 4 to 10 lanes from its I-30 junction near Weatherford to its US-80 junction near Terrell.
