Füllbachtalbrücke, Railway bridge in Bavaria, Germany

The Füllbachtalbrücke is a 1012 m long, double-track railway bridge on the Nuremberg–Erfurt high-speed line, located south of Coburg between Roth am Forst and Niederfüllbach in Bavaria. Its deck is a chain of three continuous prestressed concrete box girders, 390 m, 406 m and 216 m long, carried by 17 piers up to 40 m high. It crosses the Füllbach valley, the B 303 road and the Coburg–Lichtenfels railway.

The bridge was tendered in spring 2008, with work on site starting in spring 2009. The last span of the superstructure was concreted on 4 April 2011 at the southern abutment, and remaining work ran until 2012. The contract sum was about 26.5 million euros.

The bridge crosses the Füllbach valley between Roth am Forst and Niederfüllbach, south of Coburg in Bavaria. Its 63 m main spans over the B 303 and the Füllbach were widened for road sight lines, while the neighbouring 53 m spans were shortened for design reasons. An information point once stood at the Rennbergweg near the northern end.

The structure is part of an active railway line with regular train traffic and should only be viewed from a safe distance. The best view of the bridge can be had from surrounding paths or observation points in the valley.

The launching girder used to build the deck was developed specifically for this bridge: 138.6 m long and about 900 t, with two 4 m deep box girders and a 33.6 m nose. A tower crane was mounted on its side, and the deck advanced north to south in three-week cycles.
