The X-ray Bridge is the third bridge with this name in the Berlin-Charlottenburg district and dates from 1960. It replaces an iron arch bridge for road traffic that was completed in 1908 and which was built in place of a wooden footpath laid out in 1897. This construction was destroyed at the end of the Second World War. The pedestrian bridge was named Röntgenbrücke in 1902 in honor of the German physicist Wilhelm Conrad Röntgen .
history
The gas works in Charlottenburg near Berlin , built in the early 1890s, supplied all the surrounding houses and factories with town gas. In 1897, the supply pipes were fitted with a wooden footbridge that could also be used by pedestrians to safely transfer the gas pipelines across the Spree. With the increase in traffic, the expansion of Charlottenburg as an industrial location and the competition with the nearby city of Berlin , the councilors had a fixed road connection planned over the Spree. From 1906 to 1908, the companies assembled a steel bridge with a truss-like arch on top. It spanned the Spree in one piece and had a span of 71 meters. The abutments were based on massive granite blocks that had been embedded in poured and rammed concrete on the north and south banks of the river. The maximum construction height was 7.11 meters. The bridge did not receive any special jewelry. This crossing of the Spree was also blown up by Wehrmacht troops in World War II shortly before the German surrender . The damage was so severe that rebuilding was out of the question, only the iron parts were removed from the river bed. Between 1954 and 1960 the Berlin Senate had a completely new bridge built. Now a prestressed concrete bridge was placed on the stable foundations that were still in place. A flat frame with a width of 12.3 m serves as a support for the bridge deck, which contains two lanes and two sidewalks.
From 1994 to 1997 the Berlin engineering office Jagels carried out a renovation of the bridge structure on behalf of the Senate Department for Urban Development.
In the neighborhood
The current operator of the power station Charlottenburg, the company Vattenfall , has returned a shoreline of their land to the city of Berlin, on the between the Caprivi bridge and the X bridge the promenade ( "On Spreebord") was reinvested in the year of 2007.
