The Schenkendorf Bridge is a bridge for trams as well as for cyclists and pedestrians over Schenkendorfstraße in Munich .
It was built for tram line 23, which opened in 2009 , which first ran from Münchner Freiheit via Leopoldstraße , then on the route of a former industrial track northwards via Schenkendorfstraße, i. H. drive over the middle ring to the so-called Parkstadt Schwabing .
At the place of the Schenkendorf Bridge there was a railway bridge until 1990, on which the branch line from the Munich Nordring to the Munich-Schwabing freight yard crossed Schenkendorfstrasse.
description
Over a length of 84 m, the Schenkendorf Bridge crosses the enclosure of four lanes coming from the Petuel Tunnel and Leopoldstrasse, the open four lanes of Schenkendorfstrasse leading into the tunnel and to Leopoldstrasse, the wide sidewalks and cycle paths on both sides and from not visible from the outside - a tunnel tube of the Petuel tunnel on the southern side.
The cable-stayed bridge has two separate, slightly upwardly arched bridge decks, both of which hang from a sloping, approx. 34 m high mast. The floor plan of the tram bridge with two tracks and narrow service routes on both sides runs right under the inclined mast, the cyclists and pedestrian bridges form a slight curve around the other side of the mast. Both bridges are only connected by three cross members. On both sides of the tram bridge, these cross girders are attached to the mast head with six inclined, 10 cm thick ropes. The pedestrian bridge rests on the cross members outside of the stay cables. The mast is anchored with four ropes to the south next to the tram tracks and two ropes to the west next to the housing.
Long green ramps lead up the grass tracks and the footpath and bike path to the bridge's abutments. The bridge can also be reached via stairs from both sides of Schenkendorfstrasse. On the south side, the Am Münchner Tor stop, named after the neighboring skyscraper , is located directly in front of the bridge, but not exactly along its longitudinal axis, so that a slight curve adds to the variety. On the northern side, the route only describes a slight curve at the lower end of the long ramp, the footpath and bike path already depart from it at the upper end.
Technical details
The 69 t mast stands on a side tunnel (exit to the Munich - Nuremberg motorway ) of the Petuel tunnel , the ceiling of which was therefore reinforced from the normal 70 cm to 150 cm during the construction. The ceiling has to carry a load of 2200 tons at this point. The western anchoring is also integrated into the tunnel block. The anchor block of the four southern guy ropes directly at the stop is part of the concrete abutment that has been extended to that point.
The 7.40 m wide girder of the tramway bridge consists of a girder grid, which is formed by two box-shaped main side girders and four side girders in the axis of the rails as well as the box-shaped main cross girders and other, smaller cross girders. The girder grid has a construction height of 1 m. The tracks are laid on the bridge as slab track . Outside the abutments, the tracks have long rail extension devices to compensate for changes in length of the bridge due to temperature fluctuations.
The footbridge and cycle path bridge is 4.50 m wide on the inside and consists of a torsion-resistant box with an orthotropic plate and cantilevered cross beams at a distance of approx. 3 m. For rescue and service purposes, it is also designed for a 16 t vehicle.
The client was the state capital Munich, whose building department was in charge of the project and site management. The project planning and design was done by Mayr Ludescher Partner, consulting engineers with Auer + Weber + Assoziierte, Free Architects BDA, the structural planning also comes from Mayr Ludescher Partner. The steel bridge was built by Maurer Söhne .
