Autobahns of Austria
Unlike German autobahns, on Austrian autobahns a general speed limit of 130 km/h (81 mph) is set, although as of August 25, 2018, the FPÖ government has been going on a trial for a possible speed limit increase to 140 km/h (87 mph) on the Autobahn 1 freeway. They may only be used by powered vehicles that are designed to achieve at least . While on the motorway voluntary stops, U-turns and backward driving are prohibited.
Bundesautobahn 24
On that road, there is a 150 km (93 mi) long section that has no speed limit at all (only a recommended speed of 130 km/h), which means that about 65% of that Autobahn can be driven at very high speed.
Planning for the autobahn began as far back as the 1930s; before World War II numerous bridges and sections of roadside shoulder were built between Hamburg and Berlin. The German divide, however, put a hold on further work and it was not until 1978 that construction was resumed, carried out by a GDR work force and paid for by West Germany. In 1982 the A 24 could finally be opened. Most pre-war bridges could not be used, however, and were replaced by new structures.
