History Edit
18 Wheels of SteelEdit
The highway first appeared in SCS Software's first trucking game, Hard Truck: 18 Wheels of Steel, where it connected the cities of Los Angeles and Las Vegas on the West Coast map, as well as Salt Lake City and Helena on the Rockies map.
I-15 can also be found in several later 18 Wheels of Steel games: In Across America it connects Interstate 40 with Salt Lake City and Great Falls and in Pedal to the Metal, Convoy, Haulin' and American Long Haul it also passes Las Vegas.
American Truck SimulatorEdit
In the initial version of American Truck Simulator, Interstate 15 began at a trumpet interchange with Interstate 10 east of Los Angeles and headed north to Las Vegas. The small town currently on SR 58 west of Barstow near which exists a Coastline Mining quarry was situated on Interstate 15.
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 1.29, the section of Interstate 15 from Los Angeles to San Diego was added, along with the current four-level stack interchange with Interstate 10 and the cloverstack interchange with Interstate 8.
In the initial version of the Utah map expansion DLC, the section of Interstate 15 from US 93 in Las Vegas to Interstate 84 and US 91 in Brigham City was added.
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 Rusell 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.
In the initial version of the Idaho map expansion DLC, the section of Interstate 15 from SR-30 in Riverside to US 20 in Idaho Falls was added.
