is an autobahn in southwestern Germany. It connects the Mainz area to Kaiserslautern and the A 6 and is therefore an important connection between the Rhine/Main and the Saar areas. It was constructed during the 1980/90s and finished in : last section Sembach to Kaiserslautern.
Historically an uninterrupted Autobahn, one final 10km (10miles) section was added between Sembach and Kaiserslautern at the current site of the Dreieck Kaiserslautern/KL-Zentrum Ausfahrt. This relieved the heavy traffic on the two lane Bundesstraße 40.
