Bundesautobahn 656


is an autobahn in Germany. It leads from Mannheim-Neckarau to Autobahnkreuz Heidelberg.

History

The planning for an Autobahn between Mannheim and Heidelberg began as early as 1926. It was taken into account in the planning for the HaFraBa. It originally stretched from the eastern end of Mannheim to Heidelberg, Bergheimer Strasse. The end sections of the autobahn became part of State Highway B 37 in the 1990s, thus shortening the autobahn from its original to. At the same time most of the crossing bridges were torn down and rebuilt with enough space to make room for an emergency lane on both sides. Until the mid-90s there was no speed limit on the A 656; today the speed limit is 120 km/h.
