Mangfall Bridge

Destroyed at the end of World War II, this bridge was replaced with a temporary structure in 1948; the current bridge consists of a replacement built in 1958–60 to a design by Gerd Lohmer and Ulrich Finsterwalder and a second span for traffic in one direction which was added in the late 1970s when the autobahn was widened to six lanes.

[1] Hitler selected German Bestelmeyer's design;[2] with a single deck and only two massive support pylons, in concrete rather than steel, it was preferred on aesthetic grounds, and a model of one of the pylons dominated the Reichsautobahn section of the Gibt mir vier Jahre Zeit (Give me four years) exhibition of Nazi achievements in 1937.

A temporary steel truss bridge of the type designed by Gottwalt Schaper and used on the Reichsbahn was used on the rebuilt pylons, carrying one lane of traffic in each direction, and in 1958 this was moved to one side and beside it to the south, a supplemental pillar was erected beside each pylon.

When the new replacement roadbed was complete, the temporary bridge was disassembled and the supplemental pillars demolished.

In 1957, Dyckerhoff & Widmann (Dywidag) won the contract to build a permanent replacement bridge to a design by Gerd Lohmer and Ulrich Finsterwalder.
