Wikipedia:<br><br>First suspension bridge from 1925<br><br>in 1909, the construction of a suspension bridge was decided the first world war interrupted the execution, which could be resumed again until 1920 however. The bridge was 376 m long and had a wingspan of 272 m. Their 62/68 m high pylons were made of masonry and were themselves connected by a wall of masonry. The bridge deck was stabilized by lateral steel truss frame. The bridge had a clearance height of 38 m.<br>The suspension bridge was opened on December 13, 1925. She had the largest span of all European suspension bridges at the time.[2]<br>On August 24, 1944, the bridge was blown up by the retreating German troops.<br><br>Second bridge 1951<br><br>After the war, built a new bridge in the same place with the same mass. However slim pylons made of reinforced concrete were built on the existing foundation of the pillar. Growing traffic with increasing vehicles the disadvantage of bridge built between steep slopes showed cross over the River: the ends of the bridge had to turn the road almost at a right angle. That slowed traffic considerably. In the encounter of semi-trailers, one had to wait until the other was passed. Also, damage to the concrete pylons was determined by an alkali-silica reaction. The bridge is therefore since 1992 under precise observation. She should be canceled 2013.
