The Havel Bridge Werder is a motorway bridge over the Potsdamer Havel in the urban area of Werder (Havel) . It is 704 meters long and leads the federal highway 10 over the river.
history
At the beginning of the 1930s there were plans to build a motorway bridge over the Zernsee of the Havel as part of the construction of the motorway around Berlin, today's A 10 . In 1935, the Potsdam District President Ministerialdirektor From announced preliminary planning specifications. The bridge over the Zernsee south of the village of Phöben should completely span the entire width of the water. In order to ensure safe passage for inland shipping, at that time mainly tow trains with several attachments, the main passage opening should be at least 75 meters. This was mainly due to the strong westerly winds that often prevailed here. If, for reasons of bridge construction, only a narrower passage width is possible, two bridge passages would have to be selected, one each separately for the downhill and uphill journey. The bridge was supposed to cross the Potsdam Havel at the height specified by both banks. It is worth mentioning that the opinion of the Imperial Yacht Club in Potsdam was obtained on the clearance height for hiking dinghies with a mast height of up to 6 meters. These should be able to pass the bridge without having to lay the mast. In 1936, the preparatory work began. The connecting embankments were filled and leveled. The construction of the pillars has started. Engineer Zühlke from Niesky was the responsible site manager . Zühlke later also managed the construction of the motorway bridge over the Teltow Canal in Dreilinden . For the population of the surrounding villages and also for the city of Werder , bridge building and the construction of the motorway were a welcome opportunity to earn income. The bridge was opened to traffic in the early 1940s. Due to the war, however, a section of the western Berlin ring remained unfinished, so that it was hardly used. The bridge survived the Second World War undamaged. The section between the Potsdam-Nord junction and the Havelland triangle was not completed until 1979.
A two-level continuous steel girder bridge with a length of 704 meters and eleven openings as well as spans of 55 meters in the two end fields and 66 meters in the inner fields was built. Four piers were founded with the caisson technique at a maximum depth of 28.65 meters below the water level on a stable layer of sand, as digested sludge is present up to 16 meters below the river bed. The reinforced concrete caissons with an area of 13.5 × 27.5 meters were made on the bank, floated in with barges to their final location and then lowered. From 1995 to 1997 the superstructure of the Nauen carriageway was replaced by a new steel structure. From 2002 to 2004 the superstructure for the Werder carriageway was replaced.
