American Truck Simulator's South Dakota Is Out: 13 Cities, Mount Rushmore and About 3,000 Miles of Road

The Mount Rushmore State is finally on the American Truck Simulator map. SCS Software released the South Dakota DLC on Sept. 24 at the end of a launch livestream that included CEO Pavel Šebor, three weeks after it set the date with a trailer on Sept. 2. Traxion notes the state was first announced in June 2025, so this one has been a long haul.

SCS says the expansion recreates around 3,000 miles of real-world roads. There are 13 cities, including Sioux Falls, Rapid City and Pierre, plus 21 towns and settlements such as Hot Springs, Wall and Sturgis. The road network connects to Montana, Wyoming, Nebraska and Iowa, and Traxion points to Interstate 90 and Interstate 29 as the main arteries.

What you can see from the cab

The landmark list is what most players will chase first. SCS calls out Mount Rushmore, the Corn Palace, the falls in Sioux Falls and the Dignity of Earth and Sky sculpture above the Missouri River, along with the Black Hills, the Badlands and the landscapes around Reva. Traxion adds the Crazy Horse Memorial, underground mining tunnels and red-brick town streets to the list.

The terrain is the point. South Dakota goes from the flat farm country of the Great Plains to the rock formations and tight forest roads of the Black Hills, which is exactly the kind of variety that makes a long haul in a truck sim feel like a road trip instead of a commute.

New industries and 10 custom depots

SCS built 10 custom depots for the state and added new industries, including trailer manufacturing, residential housing and a food production facility in Sioux Falls. Traxion also points to agricultural businesses on the map.

A World of Trucks event to go with it

SCS launched a World of Trucks event called Cruising South Dakota alongside the release. The personal goal is to complete deliveries to or from all 13 South Dakota cities, which earns a World of Trucks achievement and a Call of the Badlands paint job for ATS trucks. There is also a community goal of 150,000,000 miles driven on South Dakota deliveries, and players who finish their personal goal get a Ring-necked Pheasant item. Run External Contracts or External Market jobs to or from Rapid City and you can earn a Quartz Triceratops to hang in the cab.

SCS did not list a price in its release post. Ahead of launch, Traxion noted that recent ATS map DLCs had sold for £9.99 and that the previous one, Illinois, came out in May.

For anyone who builds trucks in real life and drives them in a sim at night, South Dakota is a big one. The I-90 run from Sioux Falls to Rapid City, a climb into the Black Hills and a stop in Sturgis are now a few clicks away. SCS put it simply in its launch post: "We can't wait for you to start explorin'!"
