[Guide] ATS 1.57 – 100% Explored map with all DLC (with Louisiana)
I explored 100% of Pelican State finally and in the video I’m sharing the guide how to do it on your side as well as tools and files. Text file with discovered items and fresh profile with opened map. Please note that these files are actual for current state of the game in January 2026 on ATS 1.57 and can be partially will work on later versions but always check if the new update available for this topic.
Obviously you need all map DLC and as always I would like to remind you to back up before doing anything with your profiles.

Hidden Roads Study – December, 28 2025
As you know I’m sharing found hidden secret roads in both American Truck Simulator and Euro Truck Simulator 2 periodically. While ATS hidden roads guide has been updated with 245 roads, in ETS2 1.57 we have a lot of new roads in refreshed Scandinavia and Nordic Horizon DLC, and I’m still discovering them. I hope I will update the guide in the beginning of 2026 but it can take more time.
Actual list of cities with hidden roads for Europe and America will be updated periodically here https://trucksim.top/y9t6. It is probably won’t help you with exact secrets locations but you can check if you missed any.
ETS2 (updated 04.25.2025, actual on 1.57 without Scandinavia Refresh and Nordic Horizon DLC, 80 roads so far)
ATS (updated 12.26.2025, actual on 1.57 with Louisiana DLC, 245 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Unfortunately, YouTube search results often prioritize older videos, so even though I’m updating descriptions, outdated guides still rank higher in search results.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.

100% discovered study 12.27.2025
It is so many map related news in our favorite truck simulator games, so on my side most previous guides and files are currently outdated. But I have some progress – ATS on 1.57 with new Louisiana DLC is almost done and the guide will be released in 2025, but in Europe I have only 92.75% with Nordic Horizons and Scandinavia refresh. So European update will take time and will be released in 2026. I concentrated on finding secret roads as well so while in US it is all shown in video, for Nordic Europe I found dozen of roads and discovery is still goes on.
If you’re still on 1.56 below you can find guides for both games. They will work on newer versions but undiscovered areas will remain grey.

100% Explored map with all DLC in ATS 1.56 * Full Map Discovered, Guide, Profile (September 2025, ATS 1.56, all map DLCs up to Iowa)
Since 2017 I discover whole map almost on every game versions including all expansions and reworks. Some map updates take a lot of time but some is pretty small and can be discovered in couple days. Nordic Horizons, refreshed Scandinavia and Louisiana will probably finished in 2026. And as soon as my progress will be finished I will share it on Youtube and here the blog.
245 Hidden Roads in ATS 1.57 (with Louisiana). Secret Roads, Towns and Easter eggs
The guide contains 245 hidden roads in 19 states (including Louisiana DLC) on American Truck Simulator. It is actual for January 2026, on ATS 1.57.
Some roads are periodically disappear during map reworks and some new are being added in new game versions. Mostly I added marked roads but also some easter eggs are available.
And we are waiting the new states in 2026 – announced Illinois and South Dakota, expansion to Canada in British Columbia.
I tried to avoid spoilers, mark only locations and removed hidden roads footages but if you prefer to to discover all hidden roads and secrets yourself better to skip the video.
Hidden and secret roads doesn’t affect percentage of map discovery.

Cruising Louisiana event is still goes on
As always with the new DLC for American Truck Simulator we get World of Trucks event and this time it’s #CruisingLouisiana – typical but still attractive since we can discover new state and get another trophy on ours Wotr page.
Rules and rewards are pretty equal as for other “Cruising” events so if if you played it once just apply to the new names or read details in SCS Blog.
Christmas 2025 World of Trucks Event
Traditionally in December we get a new event from SCS Software and as last couple years we will do deliveries to Winterland – fictional country with frosty roads, snowing and magic locations. #WovenWondersOfWinterland in 2025 getting a massive update – now in mystical area we have AI traffic so hauls will not look like we are the only truck in this area.
Details, rules and rewards as always explained on SCS Blog. As always I wish you happy trucking. Drive save on frosty roads.

It is all work in progress for now and not all details of new map DLC are clear but at least we know that following cities will be presented: Bloomington, Champaign, Chicago, Effingham, East St. Louis, Marion, Moline, Peoria, Rockford, Springfield, Quincy.
After Illinois we will see another state DLC – North Dakota and the next step hopefully will be in Canadian British Columbia expansion.
