For current public versions of the ATS on version 1.57, we are good. But after release of open beta for 1.58 we have about 4% of undiscovered roads – result of massive Rout 66 Rework. So, on my side it’s 96,29% and not only in states on the Route 66 but almost in all US territories probably since garages has been updates in whole map of current game. Good news for those who like to explore new roads. Reworked roads in 1.58 by mileage are bigger that one of the smallest states (like whole Iowa). I’m planning to hit the road on this weekend but my 100% in 1.58 is far away, so the next guide will be after the final release of ATS 1.58 or even after the new DLC will be delivered (I remind you that Illinois is also will be released this spring).
