Faller-Klamm-Brücke, Road bridge in Lenggries, Germany

The Faller-Klamm-Brücke, also called the Sylvensteinsee Bridge, is a 329-metre road bridge on the Bundesstraße 307 between the dam and Neu-Fall in the Lenggries municipality. Its steel girder deck with asphalt surface runs on eight equal spans over seven slender concrete piers that rise about 20 metres above the average water level. The bridge is 7.5 metres wide, with one lane per direction, and its S-shaped course follows the best rock for the pile foundations.

The bridge opened in 1957 to improve traffic connections in the mountain region and allow faster access between communities on both sides of the lake. The project was part of post-war infrastructure development that supported growing mobility needs.

The B307 over the bridge is part of the Deutsche Alpenstraße, the German Alpine Road route into the Karwendel mountains, and carries heavy tourist traffic. The bridge is known locally as the "Sylvensteinsee Brücke" after the reservoir it crosses between the dam and Neu-Fall.

The bridge carries the B307 between the dam and Neu-Fall, with one lane per direction and a 7.5-metre width, so expect narrow crossing space. It lies on the Deutsche Alpenstraße route toward the Karwendel mountains and is heavily used by tourists, so time crossings outside peak holiday traffic. The S-shaped course follows the bedrock chosen for the pile foundations.

The bridge's S-shaped plan was dictated by the rock best suited for the pile foundations, and its seven slender concrete piers rise about 20 metres above the average water level. Construction began in September 1955 and was completed in October 1957 at a cost equivalent to about 2.25 million euros.
