Grubentalbrücke, Railway arch bridge in Goldisthal, Germany.

The Grubentalbrücke is a railway arch bridge in Goldisthal's valley that carries two tracks across a gorge. The structure features two separate concrete supporting legs with a deck that varies in width along its length.

The bridge belongs to the Ebensfeld–Erfurt high-speed line and lies between the Goldberg and Dunkeltal tunnels. Its lot, including the northern Bleßberg tunnel section and the Saubach bridge, was awarded in June 2008 for €138.8 million net; the shell was finished at the end of 2013. The design was revised in 2008 into a semi-integral structure, and in 2015 Schlaich Bergermann und Partner received the Ulrich-Finsterwalder engineering prize.

The engineering team from Schlaich Bergermann and Partner received the Ulrich-Finsterwalder Engineering Prize in 2015 for their work on this structure.

The bridge lies between the Goldberg and Dunkeltal tunnels on the Ebensfeld–Erfurt line, west of Goldisthal in South Thuringia. It is a rail structure with no public access on the deck; the arch and the 35 m drop to the valley floor are seen from the surrounding slopes and paths.

The arch is not a single rib but two massive concrete legs, slightly splayed apart, about 1.7 m thick at the springings and 3.3 m below the crown. The deck fuses with the arch over roughly 35 m at the apex, and the semi-integral design leaves bearings only at the abutments.
