location

The Werksbrücke West is a private road and rail bridge over the Main in Frankfurt am Main . It is located on the western border of the Höchst industrial park at Mainkilometer 22,030.

Its only pylon standing on the left bank of the Main has two vertical stems made of reinforced concrete, which stand with a pillar spacing of only 8 m on both sides of the central axis of the 30.95 m wide bridge deck. This cross-section is based on the division into a central area with a railroad track and pipelines and, separately from this, the two outer sides, each with a two-lane carriageway and a sidewalk.

It was from 1970 to 1972 for the former Hoechst as a cable-stayed bridge with a prestressed concrete superstructure in cantilever built. The bridge planned by Ulrich Finsterwalder and Herbert Schambeck together with the architect Gerd Lohmer and built by Dyckerhoff & Widmann was the first concrete bridge designed as a cable-stayed bridge for rail and road traffic. It was also the first harp-shaped cable-stayed bridge in which numerous stay cables were arranged close together. Your carriageway girder consists of a continuous prestressed concrete box girder that is stiffened every 3 m by cross girders.

The river field has a span of 148.23 m. The client had requested that the pipeline in the south should leave the bridge after around 95 m and that the bridge itself should end shortly thereafter. That is why there was only a short anchoring area available, so that not the entire main opening above the Main was attached to the pylon. Instead, so-called concrete sails were placed on the north bank pier , two pairs of cantilever beams made of prestressed concrete that protrude around 30 m over the river and over the bank area.

Most of the in-house truck traffic between the north and south works is carried on the eastern lane facing the plant. It also serves to develop the Rhine-Main container port, which was inaugurated in 2004 . On its west side it carries a publicly accessible private road. It leads as an elevated road on the factory wall to the Sindlinger roundabout at Tor West . Another ramp is located in the old town center of Sindlingen . This private road has been closed to motorized traffic for several years.
