Open Beta for the 1.57 is now available to try and test out!

1.57 is a big update which not only include a lot of game improvements and features but also a bridge to new maps DLCs for both ETS2 and ATS. Louisiana for ATS and Nordic Horizons for ETS2.

Update for Euro Truck Simulator is now available and the American one will probably will come soon as well. In Europe 1.57 brings the long-awaited refresh for the Scandinavia DLC with not only updated textures, vegetation, road assets rest stops and fuel stations but also major overhaul of the road network: custom-designed junctions replacing old prefabs and map additions, including the brand-new cities of Aarhus in Denmark and Karlstad in Sweden, along with a completely rebuilt Copenhagen featuring modern infrastructure and landmark recreations to enrich the network and scenery.

We still have no evidence of new hidden roads coming with this refresh but hope we will add some secrets to the guide.
