Motorway A 4 passes north of the Thuringian Forest, while A 71, intersecting the former south of Erfurt, crosses the range from the northeast to the southwest, passes under the ridge in the Rennsteig Tunnel near Oberhof, and is joined near Suhl by A 73. Two more long-distance roads, Bundesstraßen 19 and 84, pass over the western parts of the range, while Bundesstraße 88 skirts the northern foothills between Eisenach and Geraberg.
