Warsaw Bridges ( Polish mosty Warszawskie ) is a group of Oder and Oder Canal bridges in Wroclaw . The former Hindenburg Bridge from 1914 to 1916 was supplemented by a new parallel bridge from 2006 to 2008.
history
Predecessor bridges
Until 1870 Hundsfelder Chaussee bridged the Alte Oder with a wooden bridge. This was then replaced by a four- bay steel lattice girder bridge on masonry pillars, which was called the Hundsfelder Bridge . When the city canal was built to the left or southwest of the Alte Oder in the course of the construction work for the new city port facilities from 1892–1897, this was bridged in the extension of the Hundsfeld Bridge from 1870 by means of a steel truss bridge.
Old bridges
At the beginning of the 20th century, the city canal, built a few years ago, became a bottleneck for inland shipping , so that a new large shipping route was tackled. In the area of the eastern Hundsfelder Bridge, the mouth of the new Barthelner Canal was to be created to the right or northeast of the Alte Oder. Due to the required clearance and the old age, the old eastern Hundsfelder Bridge was replaced by a concrete arch bridge a few meters upstream. The new bridge, designed by Günther Trauer , was opened in 1916 and named the Hindenburg Bridge in honor of Paul von Hindenburg . In the years 1927–1928, the western bridge from 1897, which kept the name Hundsfelder Brücke until 1945 , was replaced by a significantly wider concrete slab bridge so that the road could be widened directly in front of the fork in Matthiasstrasse and Neue Adalbertstrasse.
The bridges survived the Second World War unscathed and were renamed in 1945 first in most Karłowicki (Karlowitz Bridge) and later in most Warszawski (Warsaw Bridge). The bridge was renovated in the early 1960s and 1987–1988.
New bridges
The eastern and central Warsaw bridges, which are only 7.5 m wide, led to one of the main arterial roads and two tram tracks. To expand the capacity and to protect the old bridges, a second bridge was built in parallel upstream in 2006-2008, which takes the tram tracks and the carriageway to the east, while the journey west continues through the old bridges. The load tests were carried out on May 6, 2008 and the new bridges were opened to traffic six days later. Finally, the old bridges were renovated again.
description
The old eastern bridge consists of six concrete arches and a pair of raised reinforced concrete arches with an attached roadway. The suspensions are made of concrete with cast iron inserts to transmit tensile forces ( Emperger system ) . The 2.25 m wide sidewalks on both sides of the 7.50 m wide carriageway are flanked by reinforced concrete parapets. While the southern pavement can no longer be used after the new bridges have been added, the north-facing pavement was separated from the roadway by means of a steel bar railing in accordance with Polish building regulations.
The new eastern bridge is a steel / reinforced concrete composite box bridge with an arched reinforcement of the pressure zone in the longest yoke.
