Autobahns of Austria
The Austrian autobahns are controlled-access highways in Austria. They are officially called Bundesstraßen A (Bundesautobahnen) under the authority of the Federal Government according to the Austrian Federal Road Act (Bundesstraßengesetz), not to be confused with the former Bundesstraßen highways maintained by the Austrian states since 2002. The allowed topspeed is 130 km/h for cars up to 3500 kg.
