The University Bridge (n) ( Polish mosty Uniwersyteckie ) is a two-part bridge train that spans the city ​​or in Wroclaw across from the main university building . It connects the old town with the Odervorstadt (Polish Nadodrze ).

history

Old Oder Bridge

Under the name Pons Viadri the oldest known forerunner of the Oder bridge in 1397 was mentioned (or bridge). The wooden bridge lay downriver from today's bridge, with the left, southern bridgehead west of the former Kaiserburg, opposite the confluence of the prison lane and the right, northern bridgehead a few meters west of the current location. The bridge was rebuilt several times, in particular a branch bridge had existed since the early modern times, which connected it with the Bürgerwerder (now Polish: Kępa Mieszczańska) , a larger island in the Oder.

University bridge from 1867 to 1869

After part of the eastern Oder bridge in Wroclaw was replaced by a wrought iron construction with the sand bridge in 1861, the magistrate decided on a large-scale renovation and expansion program for the bridges. In the course of this, new bridges were planned and built above and below the existing ones (the later Königs- and Wilhelmsbrücke as well as the Lessingbrücke ) and the still existing dilapidated wooden bridges were replaced by bridges made of wrought iron. For the technical planning of all these bridges, the responsible city building officer Ferdinand Alexander Kaumann hired the famous bridge builder Johann Wilhelm Schwedler . The first two parts of the Oder Bridge were tackled in 1867. The decision was made to go to a more convenient location directly opposite the gateway to the university building. A dam was built up from the Bürgerwerder to connect it to the new bridge.

The constructive analysis has shown that a two-bay short bridge in the southern section (in front of the university building) and a three-bay long bridge in the northern section are the best solution. The three river piers and the bridgeheads were built on concrete and made of granite blocks and sandstone in the upper area . The bridge yokes, each constructed as a Schwedler girder, were moveable on the river pillars, while the bridge heads were rigidly supported. The 6.28 m (20  foot ) wide carriageway between the Schwedler girders was paved on cast iron slabs, the 2.20 m (7 foot) wide pavements made of natural stone with sand bedding on both sides on cantilever cross girders. Neat gas lanterns were set up over the bearing points of the carriers. The Oder bridges, which were completed after two years of construction in 1869, were now called the University Bridge, as the old name was too undifferentiated with regard to the other newly built bridges over the Oder.

In the 1880s, tram tracks were laid on the University Bridge.

University bridge from 1933 to 1934

The carriageway, which was still generously dimensioned at the time of construction, turned out to be too narrow in the early 20th century. To remedy this, another bridge was built in two lots, the Werder Bridge approx. 200 m downstream, in 1905 and 1930. Then a decision was made to modernize the university bridge, which is now over 60 years old. Since no tram tracks had yet been laid in the Werder Bridge, a temporary wooden bridge was built above the University Bridge for the renovation period, which carried a tram track and a sidewalk that could be used in alternating traffic. The pillars from the old university bridge could continue to be used, now with new, laterally cantilevered and much wider flat superstructures.

The bridge was severely damaged in World War II, so that it was not opened to traffic again until 1947 under the name translated into Polish.

description

The university bridge , which consists of two sections, is a bridge on riveted multi-span steel beams, which rest on granite-walled river pillars (two in the case of the northern bridge and one in the southern) and bridgeheads. The river pillars are not oriented at right angles to the bridge axis, but correspond in their inclined position to the direction of the two river arms. The four-lane roadway made of asphalt concrete accommodates two grooved tram tracks in the middle . The sidewalks on both sides with cycle paths marked by the change of pavement are covered with steel bar railings. The terrace on the eastern tip of the island of Bürgerwerder in the middle of the bridge is bordered by a similar railing. The Fürst-Vitold-Straße (ulica Księcia Witolda) opens opposite the terrace .

Remarks

  1. Since these are two separate and spatially separated constructions, bridges in the plural form ( mosty ) are used in official language . In everyday life is a bridge ( most spoken) even if the entire bridge section is meant.
