Schlossbachgraben Bridge
The Mittenwald Railway (also known as the Karwendel Railway) was built between 1907 and 1912. under the direction of engineer Josef Riehl – and was never going to be an easy project. The steep rock face of the Martinswand dropping sharply into the Inn valley and the rugged Schlossbachgraben presented the greatest construction challenges. In the Schlossbachgraben, the solution was a reverse loop and several viaducts – among them the Schlossbachgrabenbrücke, a steel trussed arch bridge, 66 metres long, some 60 metres above the water.
The Mittenwald Railway (Karwendel Railway) was the first fully electrified railway in Austria, opened in 1912. Over 32 kilometres, the line runs through 16 tunnels and across 18 bridges and viaducts. For its length, it was one of the most expensive railway projects of its time – one look explains why.
The Schlossbachgraben bridge is the most iconic structure on the line. It spans the Schlossbachklamm near Reith bei Seefeld as if it had always been there – since 1912, it has.
