The Eddersheim Main Bridge is a 324 m long double-track railway overpass on the high-speed Cologne – Rhine / Main line .

The building is located in Hesse near Eddersheim , a district of Hattersheim am Main , north of the parallel Autobahn 3 . It spans the Main at Main km 14.260 at a maximum height of 20 m. At 130 m, the bridge has the largest span of all bridges on the high-speed line and, after the Main Valley Bridge in Gemünden, the second largest span of a prestressed concrete girder bridge for railway overpasses in Germany.

The overpass was built from 1997 to 2000. The construction costs were around 21 million D-Marks (around 11 million euros).

The maximum permissible speed on the structure is 220 km / h.

Foundation and substructures

The abutments and pillars have a flat foundation . The excavation pits for the pier foundations were made with the help of a 15 m long sheet pile wall . To minimize settlement, the concrete foundation was connected to the sheet pile wall using headed bolts . Due to the load case of a ship impact, the two main pillars on the Main have a massive cross-section 14.0 m wide and 6.0 m thick. The two foreland supports have a circular cross-section with a diameter of 3.0 m and are connected to each other at the head by a cross member.

superstructure

Cross section of the superstructure

The superstructure consists of a 324 m long continuous beam with four fields. The cross-sectional shape is a single-cell prestressed concrete box with inclined webs. In addition to the longitudinal direction, the deck slab is also prestressed in the transverse direction . With a deck width of 13.5 m, the spans are 40.0 m + 77.0 m + 130.0 m + 77.0 m. The construction height is variable and is 8.5 m above the main pillars, 5.5 m in the middle of the main opening and 3.5 m at the abutments. The fixed point of the bridge is the western river pillar, which in particular transfers the longitudinal forces from braking into the subsoil. Rail extensions are available at the ends of the bridge .

execution

At the end of 1995, the planned length of the structure was 324 m.

Construction work began in May 1997. On February 5, 1998, the first pillar foundation was concreted.

The bridge was built in sections. First, with falsework the bridge parts concreted over foothills. This was followed by cantilevered cantilever construction , stabilized by the approach bridges, with cycle lengths of around 4.5 m, the cantilever arms being constructed over the Main from both pillars .

In January 2000 the then Hessian Transport Minister Dieter Posch symbolically completed the construction of the bridge in the middle with a trowel and cement.

A total of around 12,600 cubic meters of concrete, 1,450 t of steel and 380 t of prestressing steel were processed.
