Loop 20 (Texas)
State Highway Loop 20 (Loop 20), also known as the Bob Bullock Loop, is a state highway loop that partially encircles the northern part of Laredo, Texas in American Truck Simulator. It runs from FM 1472 to US 59, partially concurrent with Interstate 69W and entirely with US 59.
In real life, Loop 20 encircles the northern and eastern parts of Laredo, Texas, from the Mexican border northwest of the city to Mangana-Hein Road southeast of the city, spanning a total length of 14.869 miles (23.929 km). The featured section of the loop is roughly 21 miles (34 km) longer than in real life.
Course
Loop 20 begins at Mines Road (FM 1472), as well as the southern terminus of Interstate 69W and US 59, in the northwestern part of Laredo and travels east towards the partially completed stack interchange with Interstate 35 and US 83 north of the city; here, I-69W simply ends here, while US 59 continues to overlap with the loop across the northern side of the city. The loop passes over McPherson Road and begins to turn towards the south until ending at Saunders Street (US 59) northeast of the city, which also provides access to SH 359 via frontage roads.

Trivia
- Just south of SH 359 in American Truck Simulator, an unfinished section of Loop 20 can be found in the southeastern part of Laredo, along with a short section of Mangana-Hein Road between the loop and US 83. This indicates that this section was originally planned to be added during development of the Texas DLC; ultimately, that section was left unfinished with the initial release of the map expansion, leaving the full route of Loop 20 in ATS incomplete.
