The middle works bridge is a private road bridge over the Main in the Höchst industrial park in western Frankfurt am Main .

It was built between 1958 and 1960 in order to develop the Hoechst AG research center on the south side of the Main . It is a two-lane road bridge in prestressed concrete construction. The entire bridge girder including the two pedestrian and bicycle paths is 12.35 m wide. The bridge can be used by vehicles with a gross vehicle weight of up to 30 t . The speed limit is how limited hours in the entire industrial park, 30 km /. Heavier vehicles, e.g. B. tanker trucks must use the west bridge.

The works bridges are owned by Infraserv Höchst , the operating company of the industrial park.

The bridge was designed by Ulrich Finsterwalder with architectural advice from Gerd Lohmer and built by a consortium of Dyckerhoff & Widmann , Siemens-Bauunion and Wayss & Freytag . It is one of the early cantilevered prestressed concrete bridges.

The 365 m long bridge consists of three construction sections: the 259 m long river bridge and the 40 m and 66 m long southern and northern ramp bridges.

The river bridge has a span of 130 m. It consists of a 12.35 m wide deck and a 10 m wide, three-cell, haunched box girder . The cantilever beams are monolithically connected to the pillars and connected in the middle of the field with a shear force joint. The hollow box is also used to accommodate supply lines (steam, cooling water, waste water, technical gases) and cables for the infrastructure of the southern plant, as most of the supply and disposal companies are in the north. The lines and cables were taken into account in the structural planning with a weight of 40 t / running meter. These lines are routed underground in pipe shafts that are 37.50 m beyond the two pillars. At the lower outer edges of the box girders there are service walkways for inspection and maintenance of the pipelines, which lead down over stairs next to the pipe shafts.

The current side cantilevers were built one after another, with a CFT cantilevering, while the land-based cantilevers with regard to the low height above ground on falsework were built.

The south-facing ramp bridge is a plate-beam bridge with 2 fields of 20 m length; the ramp bridge on the north side is a plate bridge with 2 fields of 18 m and 2 fields of 15 m.

The bridge was completed within 17 months of the order being placed.

In 2009 a new supply bridge was built immediately to the west of the central works bridge, as the existing capacities of the supply lines were no longer sufficient to connect new systems in the southern works.
