Lingenauer Hochbrücke, Arch bridge in Bregenz Forest, Austria
The Lingenauer Hochbrücke is a concrete arch bridge that spans across a deep valley in the Bregenzer Ach region. The structure uses a central arching design with a hollow box system that allows it to cross the landscape without requiring supporting columns in the valley below.
The bridge was completed in 1969 as a major engineering project for the region. Its construction marked an important moment in Austrian infrastructure development, demonstrating how modern concrete design could solve the challenge of crossing deep mountain valleys.
The bridge connects two separate communities that would otherwise be difficult to reach, making travel between the villages of Lingenau and Müselbach much simpler. It has become part of everyday life for people living in the surrounding areas of the Bregenzer Ach valley.
The bridge carries road traffic and is open to both cars and bicycles traveling through the region. The crossing itself is brief, though the height and surroundings may feel striking when you look down or pause at the viewpoints along the structure.
The bridge was designed with a hollow box system that allowed engineers to span the entire valley without needing support columns in the ravine below. This approach was relatively new at the time of construction and influenced how similar mountain crossings were built afterward.
