History

The plans for a motorway between Mannheim and Heidelberg began already 1926. Starting from 1924, the Study Group was concerned for automotive road ( Stufa ) with plans for a national " highway network ". 1926 saw the establishment of the "Association for the construction of a road for motor vehicles in rapid transit from Hamburg via Frankfurt to Basel " (short HaFraBa ), who conducted the most comprehensive plans before 1933.

But even regional stakeholders planned roads for connecting individual cities: 1930 were in several summary articles with the subtitle " cities on the Hafrabastraßen " in " Hafraba Handout " the plans of the respective cities presented for connecting to the Hafraba. Among them were detailed article by Josef F. Amberger (Heidelberg ) and Adolf Elsaesser ( Director of Town Planning Mannheim, Germany) on the " highway Mannheim -Heidelberg ", which ( a motorway junction ) also described for the first time a " crossing-free distraction ".

On March 21, 1934, after the so-called " labor battle " was introduced for the Munich- Salzburg in Unterhaching near Munich, spade held at 22 construction sites for construction of imperial highway routes, including Heidelberg -Mannheim. As Reichsautobahn the route was opened in 1935 and originally extended from Mannheim -Mitte ( today Europe space with Planetarium Mannheim, Germany) to Heidelberg - Bergheim road. Builder was the North Badische roads Society.

A special feature of the autobahn was a rest stop was with a covered forecourt and petrol station, with its own entrance and exit, located between the junction Mannheim- Seckenheim and the triangle (now Cross) Mannheim ( see also the motorway junction Mannheim). After 1945, the area was seized by the U.S. Army and used as a service station for Americans. Between the two towns there was a lot of traffic because the European headquarters of the U.S. armed forces was set up here. On the opposite side then a new motorway service station was built. After the section of the A 6 between Mannheim and Walldorf Cross and A 5 were completed between Darmstadt and Heidelberg Cross, the long-distance traffic on the A656 subsided greatly, so that the rest area was closed. Today there is a rescue station, the entrance and exit ramps to the highway but were closed with guard rails.

1982 there was a tragic accident, as at the International Mannheimer aeronaut days with an parachutists fully occupied helicopter crashed on the highway and 46 people died.

With effect from 1 January 1988 the Mannheim end was downgraded to 1.2 km from the national road 37, 10 years later, with effect from 1 May 1998, Heidelberg end to almost 2 km, so now the only highway from junction Mannheim- Neckarau the motorway junction Heidelberg (inclusive) ranges. There is a speed monitoring system that monitors the speed of 70 km / h between the driveway Heidelberg Wieblingen and the end of the B 37 in Heidelberg.

The old bridges on the A656 between the motorway junction Heidelberg and Mannheim -Seckenheim which were still largely in its original condition, were demolished between circa 2004 and 2007. This space for emergency lane has been created in the area of the former bridges. The last original bridge over the A656 is now located on the B 37 nearing its end in Heidelberg.
