I’m sharing found hidden secret roads in both American Truck Simulator and Euro Truck Simulator 2 periodically. While in Europe we don’t have new marked roads since the Greece release (2024) in US we go to state after state and in latest Iowa have plenty of nice secrets. I believe in ETS2 with Nordic Horizon and Louisiana in ATS which will be released later this year SCS will show us new hidden paths and easter eggs.
It is a list of cities by states https://trucksim.top/y9t6 which won’t help you to find the roads but at least check if you missed any.

ETS2 (updated 04.25.2025, actual on 1.56, 80 roads so far)

ATS (updated 08.23.2025, actual on 1.56, 235 roads so far)

Unfortunately, YouTube search results often prioritize older videos, so even though I’m updating descriptions, outdated guides still rank higher in search results. Please always check if a more recent and updated guide is available.
