Bundesautobahn 6

Bundesautobahn 6 (translates from German as Federal Motorway 6, short form Autobahn 6, abbreviated as BAB 6 or A 6), also known as Via Carolina (between Nürnberg and the Czech border continuing to Prague) is a 477 km (296.4 mi) long German autobahn. It starts at the French border near Saarbrücken in the west and end at the Czech border near Waidhaus in the east.

The first plans for the A 6 were laid out in 1935, construction on several parts began in 1938. In 1940, construction near Mannheim was stopped when the bridge across the Rhine collapsed, killing many workers. A new bridge, the Theodor Heuss Bridge (Frankenthal), was opened in 1953. Other parts of the A 6 were completed in 1941. A part near Kaiserslautern was used as an airstrip by the Luftwaffe during World War II. After the war, it was taken over by US forces and became the Ramstein Air Base, while the A 6 was re-built south of the air base.

In the 1960s, construction was continued. One new section cut through the Hockenheimring, requiring a major redesign of the race track which resulted in the construction of the Motodrom stadium.
