PDF Lon We st Germany - Transportation Research Board The speed limits on the GDR autobahns were rigorously enforced by the Volkspolizei, whose patrol cars were frequently found hiding under camouflage tarpaulins waiting for speeders. MS-1 Thickness Design-Highways & Streets. [32] In rare cases, sections may have limits of 40km/h (25mph),[33] or on one ramp 30km/h (19mph). about 80 mph per hour. The toll is calculated depending on the toll route, as well as based on the pollution class of the vehicle, its weight and the number of axles on the vehicles. Extremely fast.

All autobahns are named by using the capital letter A, which simply stands for "Autobahn" followed by a blank and a number (for example A8). By building the bridge to traffic planes over the Autobahn allows two systems to coexist in the same space and therefore maximizes the amount of use that area of land has.
