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.

History

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 redeisgnated as Interstate 30. In 1991, the entire concurrent designation of US 80 was removed from the I-10 interchange to Dallas.

Route description

West Texas

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 and 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 Pacifico 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 due 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 the terrain grows hilly. In Weatherford, I-20 again heads back towards the east as it heads towards the Dallas-Fort Worth Metroplex.

Dallas-Fort Worth Metroplex

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, I-20 heads east towards Dallas passing through Arlington, where it is also known as the Ronald Reagan Memorial Highway.^[2] 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.

East Texas

I-20 leaves the Dallas-Fort Worth Metroplex and heads generally to the east-southeast through East Texas. I-20 begins heading to the east as it passes to the north of the city of Tyler going through pine belt region of East Texas. I-20 leaves the state of Texas near Waskom and just west of Shreveport, Louisiana.

Auxiliary route

Interstate 20 has one auxiliary route in Texas.

- Interstate 820 is a 35.2-mile (56.6 km) loop around the city of Fort Worth. It once completely circumnavigated the city prior to I-20 absorbing the southern section as part of its relocation to the south and I-30 being extended westward over the old alignment of I-20 through the center of town.^[3]
