What this mod does

Washington EXTENDED is a map by Edward Elgar that expands ATS’s Washington state into the Olympic Peninsula, an area SCS doesn’t recreate in detail. The author says it’s compatible with any mod map.

New areas

  • Clallam Bay and Beaver Lake.
  • Pysht, Sekiu, Old Royal and Ozette (the last three since version 2.0).
  • A house you can buy as a garage near Beaver Lake (version 4.0).
  • Routes on the UI map and fixed road signs.

Requirements

It requires 13 map DLCs: Arizona, Colorado, Idaho, Nevada, New Mexico, Oregon, Utah, Washington, Wyoming, Montana, Texas, Oklahoma and Nebraska. The page doesn’t give a load order.

Version

Version 5.0, released September 27, 2025, is for ATS 1.56 and only changes the manifest. The mod started in November 2024 as “ED REZONE – Washington EXTENDED” and has been standalone since 2.0. The author warns that it may have bugs and asks you to report them on his forum or Discord. There’s no confirmed version for 1.61.

It’s free and has over 24,000 downloads on TruckyMods.
