Coast to Coast – ATS Expansion Connections for American Truck Simulator

What this mod does

Coast to Coast – ATS Expansion Connections is a patch by JacobKazias that links two big US maps with roads: ATS Expansion (by Sineptorro) and Coast to Coast. That way you can use both in the same save with no gaps between them.

The page thanks MarianGMC and Geno, from the EMMN team, for letting him take over this connection.

Requirements

• ATS Expansion and Coast to Coast (both have mod pages on Holymod).
• All SCS map DLCs; the page lists 20 states, from Arizona to South Dakota.

Load order

The author gives this order, from top to bottom:

• Coast to Coast + ATS Expansion Connections
• ATS Expansion
• Coast To Coast

Version

Version 1.1.2, released October 5, 2026, is for ATS 1.61. Earlier versions came out for 1.57, 1.58, 1.59 and 1.60, so it’s updated with every game version.

It’s especially useful in big map combos, where ATS Expansion and Coast to Coast touch the same parts of the country. Bugs are reported on the author’s Discord. It has almost 10,000 downloads on TruckyMods.
