What this mod does

Grand Utopia of America is a map by MyGodness that adds a fictional archipelago, designed from scratch, to American Truck Simulator. It’s built at 1:1 scale, so distances are real rather than compressed like on the SCS map.

What you’ll find

  • Lochburn County, with towns such as Utopia, Aldmoor Point, Flatfields, Port Oxheller and Woodbridge.
  • Custom roads such as GU Route 66 and LB County Road 2.
  • Custom companies and, since recent updates, warehouses you can rent.

Requirements and add-ons

It requires the Arizona and Washington DLCs (the latter since version 1.1). The author releases separate add-ons: GUOA – Base Map Connection, to link it to the SCS map; a connection with Esterlon; and a satellite background for the UI map. The page doesn’t give a load order.

Version

Version 1.5a, released July 1, 2026, is for ATS 1.60. The map came out in June 2025 and has been updated with every game version. There’s no confirmed version for 1.61 yet.

It has over 25,000 downloads on TruckyMods and a showcase video from the author.
