Interstate 20 or I -20 is an Interstate Highway in the US state of Texas. The highway is one of the state’s major east-west connections, running from Interstate 10 just east of Kent through Midland-Odessa, Abilene, Fort Worth, and Dallas to Waskom on the Louisiana border. I-20 is 1,024 kilometers long in Texas.

The starting point of I-20 in West Texas.
In a remote area, I-20 branches off from Interstate 10, which runs from El Paso to San Antonio. One passes through desolate and uninhabited area. Along the way are Frontage Roads. The first town is Pecos, which has 9,500 inhabitants. Here one crosses US 285, which runs from Fort Stockton to Carlsbad in New Mexico. A lot of oil and gas is found in this area, and there are thousands of pumpjacks. Especially around Monahans there are endless fields of it.
The first larger place is Odessa, a city of 94,000 inhabitants. This is followed by Midland, a city of 102,000 inhabitants. Both cities form a small agglomeration, and are the center of the oil industry in this region. At the town of Big Spring, one crosses US 87, which runs from San Angelo to Lubbock, and is a major main road with 2×2 lanes. The landscape is becoming a bit greener, but it is mainly the oil industry that dominates the landscape here. The distances are quite large in this area. At Roscoe one crosses the US 84, which leads to Lubbock, and is the main connection between Dallas and Lubbock, and is therefore well developed.
This is followed by Abilene, a larger city of 115,000 inhabitants, and an important hub in the region. The first exit is US 84, which leads toward Waco. Then you cross US 83, the Winters Freeway, which is part of the ring of Abilene. US 83 runs from Childress to Junction, and is a north-south connection that serves few major towns in Texas. The small town of Baird crosses US 283, which runs from Vernon on the Oklahoma border to Coleman in central Texas. The highway runs through slightly hilly area, but there are no really big differences in height. At Cisco one crosses the US 183, which runs north from Breckenridge to Austin, the capital of Texas. This part of Texas is a bit more overgrown. South of Mineral Wells, it crosses US 281, which runs north from Wichita Falls to San Antonio. At Weatherford, US 180 joins, which until then has run more or less parallel to I-20.

The interchange between I-20 and I-35W in Fort Worth.
One then approaches the largest conurbation in Texas, Dallas and Fort Worth, which form one large conurbation through which I-20 runs for the next 110 miles. First, Interstate 30 branches off toward downtown Fort Worth and Dallas, providing an alternative to I-20. Eventually, I-30 runs more northeast toward Texarkana and Little Rock in Arkansas. Then one crosses the Interstate 820, Fort Worth’s ring road that is 77 kilometers long. Fort Worth is the 5th largest city in Texas and has a population of 653,000. The total agglomeration has no less than 6 million inhabitants. In the suburb of Benbrook you cross the US 377, which runs from Fort Worth to Stephenville. Here the I-20 has 2×3 lanes. A few miles away, SR-183 merges, and from here the road is called the Southwest Loop.
From here you pass through a much denser built-up area, and the highway has 2×4 lanes. On the south side of Fort Worth, one intersects with Interstate 35 West, one of the two branches of I-35 through the metropolitan area. On the southeast side of Fort Worth, Interstate 820 turns north to form the ring of Fort Worth. From here, 2×6 lanes run briefly, until a few miles away, where US 287 exits toward Waxahachie.
They are now entering the enormous suburb of Arlington, which has 367,000 inhabitants and is one of the largest suburbs in North America. It is the 49th largest city in the United States. Here the I-20 has 2×4 lanes. An exactly symmetrical stack junction crosses the SR-360, a north-south highway that runs through the central part of the conurbation. This is followed by Grand Prairie, a suburb of 127,000 inhabitants. There are a number of larger lakes in this suburb.
After 45 kilometers from the city you reach the city of Dallas. The first interchange is with SR-408, Walton Walker Boulevard, which can be seen as part of the Dallas ring road. Dallas has 1.2 million inhabitants and is the largest city in the vast metropolitan area. A Stack interchange crosses US 67, which runs from Dallas toward Cleburne, and is a major arterial road to the city. The highway still has 2×4 lanes here. Via yet another stack one crosses the Interstate 35 East, the eastern branch of I-35, which runs north-south through the metropolitan area. A few miles further on, there’s another stack interchange, crossing Interstate 45, which runs to Houston. Stack interchanges come and go here, because at the suburb of Balch Springs, another one follows, with US 175, the southeastern arterial road. Shortly thereafter, I-20 turns east, and Interstate 635 turns north, forming the Dallas ring road. One passes through the last suburb of Mesquite which has 137,000 inhabitants. At Terrell, US 80 merges, the last interchange in the metropolitan area.
I-20 in East Texas.
The I-20 has the normal 2×2 lanes here again. You pass through a sloping area with an alternation of forests and meadows. One passes north of the town of Tyler, which has a population of 106,000. Here one crosses US 69, which runs from Greenville to Lufkin. In this area the forests take over. The next larger town is Longview, with a population of 77,000, where it crosses US 259, which runs from Mount Pleasant to Nacogdoches. The last major town in Texas is Marshall, where US 59 runs from Texarkana to Houston. At Waskom, I-20 crosses the Louisiana border, and Interstate 20 continues in Louisiana toward Shreveport and Jackson.
