West Texas I-20 begins its eastward journey at a junction with
I-10 in a desolate region of West Texas about east of the town of
Kent. I-20 leaves the interchange with I-10 with a speed limit of until milemarker 89. I-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
Farm to Market Road 1788 (FM 1788) near
Midland International Airport. Near
Sweetwater, I-20 begins to head east as it heads toward the city of
Abilene. In Abilene, I-20 curves toward 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 toward
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 toward the east as it heads toward the
Dallas–Fort Worth metroplex.
Dallas–Fort Worth area 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 toward the east when it interchanges with
I-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 toward
Dallas passing through
Arlington, where it is also known as the
Ronald Reagan Memorial Highway. 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 toward East Texas. The Interstate varies from 4 to 10 lanes from its I-30 junction near Aledo to its US 80 junction near Terrell.
East Texas located at I-20 exit 635 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
Canton. The intersection of I-20 at
US 69 in
Lindale just north of
Tyler is the highest traffic count intersection on I-20 east of Terrell to the Louisiana state line. From Lindale, I-20 continues east, going through the piney woods region of East Texas intersecting
US 259 with
Kilgore to the south and
Longview to the north and
US 59 future
I-369 with
Marshall just to the north and
Texarkana further north along US 59 future I-369. I-20 leaves the state of Texas near
Waskom and just west of
the Shreveport,
Bossier City, Louisiana area. ==Exit list==
