Interstate 15 (I-15) is a north–south Interstate Highway in southern California and Nevada, central Utah, and eastern Idaho in American Truck Simulator. It runs from Interstate 8 in San Diego to US 20 in Idaho Falls.

Course[]

Interstate 15 in ATS begins at its junction with Interstate 8 just east of San Diego, and immediately climbs over the Peninsular Ranges to Interstate 10, the highway in this segment being six lanes wide. North of I-10, the highway continues climbing, this time over the Transverse Ranges, reaching its climax at Cajon Summit, which has an elevation of 4260 ft. This grade is rather steep, and features a slow vehicle lane for northbound traffic. North of the summit, the highway reaches CA 58 and Barstow, which offers services off the highway to the south of town. After leaving Barstow, the highway meets with Interstate 40 at its western terminus, passes the town of Baker (notable for having the world's tallest thermometer, which is visible from the road), and sets off through the desolate Mojave Desert in the south of the Great Basin.

Right after crossing into Nevada, the highway passes through the border town of Primm, and soon after moves through Las Vegas, where it intersects with US 95 and 93, the latter having a brief concurrency. Leaving Las Vegas, I-15 soon crosses into Arizona, where it runs a short but scenic stretch through the Virgin River Gorge. Leaving the gorge, the highway enters the Colorado Plateau and the state of Utah.

After crossing the state line, travelers are greeted by north and southbound Weigh Stations (which feature Rest Stops) before passing through the city of St. George. North of town, UT-9 is reached, and soon after the highway exits the Colorado Plateau, re-entering the Great Basin. It is here that the highway passes through Cedar City, and proceeds along the edge of the Colorado Plateau, which stands prominently to the east of the highway in the form of high, tree-covered plateaus. After traversing a summit, I-15 intersects with Interstate 70 at its western terminus at Cove Fort, the fort itself being accessible from the highway. After another summit, the highway encounters US 50 and the town of Scipio, and proceeds through the desert alongside the Wasatch Mountains. It soon passes Provo, and shortly afterward reaches Salt Lake City and Interstate 80, followed quickly by Ogden and Interstate 84, which begins a short concurrency. North of Ogden are north and southbound weigh stations, and further north is Brigham City, which offers travel services and access to Logan via US 89 and 91. At Tremonton, where there are more services, I-84 breaks away to the northwest while I-15 continues its northern trend into Idaho.

Soon after entering Idaho, the highway crosses the Bannock Range via Malad Summit (5574 ft) and descends into McCammon and Inkom, where notable cliffs rise over the road. After north and southbound weigh stations, Pocatello is reached, and with it, Interstate 86. The highway proceeds through the Snake River Plain and across a rather large lava field, which features north and southbound Rest Stops. Shortly afterwards the city of Idaho Falls is reached, and it is in the north of town where the highway currently ends, waiting to be extended to Montana.

History[]

18 Wheels of Steel[]

American Truck Simulator[]

  • In update 1.5, which changed the map scale from 1:35 to 1:20, several new sections were added to the existing route to accommodate the new map scale, including the truck stop south of Barstow and its accompanying exits, as well as the rest area between Barstow and Primm. The small town west of Barstow was moved to its current location, and the junction with SR 58 was changed from an at-grade three-way junction to the current trumpet interchange.
  • In update 1.38, the section of Interstate 15 from Interstate 84 and US 91 in Brigham City to SR-30 in Riverside was added. In Las Vegas, all interchanges were rebuilt. The diamond interchanges with Russell Road and Flamingo Road were changed to be reached via local lanes, and the former was rebuilt and the latter changed to a partial folded diamond interchange. The frontage road running parallel between the exits was removed. The trumpet interchange with US 95 was changed to a "Spaghetti Bowl" interchange with US 93 and US 95. The diamond interchange with US 93 on Cheyenne Avenue was separated into a single-point diamond interchange with the previous section of US 93 on Cheyenne Avenue and a diverging diamond interchange with US 93.
