The Kochertalbrücke at Geislingen am Kocher, in the municipality of Braunbach is, with a maximum height of 185 m above ground, the highest viaduct in Germany. Your 178 m high bridge piers are the highest of all beam bridges worldwide.

Go over the bridge crossing on the route between Heilbronn and Nuremberg, the Federal Highway 6, near the four-lane Geislingen Kochertal.

Bridge construction

The building spans over a length of 1128 m the valley. The prestressed concrete superstructure is a nine -span continuous beam in the longitudinal direction in a static view. The two outer fields have a span of 81 m, the seven inner boxes of 138 m each. In cross section, the superstructure is a single, rectangular hollow box of 8.6 m in width and with a constant height of 6.5 m. The deck slab is 31 m wide and everywhere at least 26 cm thick, the web of the box girder (his side wall ) is 45 cm thick. Inclined struts support all 7.67 m on both sides 11.2 m cantilevered deck slab.

The central pillar three to six are clamped into the superstructure and work with him as a frame-like structure. Together with the two columns and seven, which are equipped with fixed Punktkipplagern, they stabilize the structure in the longitudinal direction and form the fixed point. On the abutments and the piers one and eight of the superstructure is mounted for longitudinal displacement.

The eight pillars are between 40 m and 178 m high. Your hollow cross-section is tapered on all sides, single-celled and rectangular, it is above 8.6 m wide and 5.0 m thick and extends downward to the base to a maximum of 15.0 m × 9.5 m. The wall has a thickness of at least 50 cm, in the foot and head areas it reaches 90 cm. The slope pillars two and seven are established with 45 m deep shafts in the landslide-prone slopes.

The bridge superstructure was made ​​in the cantilever of hollow box cross-section. The cantilevered deck slab parts were subsequently concreted with a Nachläuferwagen. A consortium of companies Ed. Züblin AG, DYWIDAG and Wayss & Freytag AG built according to a special draft proposal of Wayss & Freytag under the advice of Fritz Leonhardt the bridge from 1976 to 1979 with reduced costs by 40%.

Repair

Since July 2013, the bridge for a total value of 14.49 million euros will be renovated and strengthened to allow in the future use with three lanes in each direction. Wherein the hollow box is amplified by the bridge abutments of the bridge and the base plate. Furthermore, additional tensioning cables are installed. On the bridge, the bridge caps, the underlying seal, the climb-over protection and safety devices to be replaced. The entire bridge drainage is replaced. At the ends of the bridge the transition structures are replaced with noise-reducing. The pot bearings on the pier heads or abutments are also exchanged. The complete renovation is expected to be completed by 2015.

Museum

To bridge the bridge and its architectural history museum was established in Geislingen. Open by appointment, it offers the visitor to know to build the bridge.
