Brenztalbrücke, Highway bridge in Giengen an der Brenz, Germany

The Brenztalbrücke is a 372 m long, four-lane girder bridge of the A7 motorway near Giengen an der Brenz, opened in 1981. It consists of two separate parallel prestressed concrete structures that cross the Brenz, the Brenzbahn railway, several roads and a 110-kV overhead power line at a height of 40 m, following a slight curve.

The Brenztalbrücke was opened in 1981 as part of the A7 motorway near Giengen an der Brenz. Its prestressed concrete deck cost 16 million Deutsche Marks, roughly 20 million euros in today's purchasing power. The bridge has carried four lanes of traffic since that opening.

The bridge carries the A7 over the Brenz, the Brenzbahn railway, several roads and a 110-kV power line at a height of 40 m. Its two parallel prestressed-concrete decks run side by side in a slight curve, so drivers cross the valley without noticing the railway and river beneath them.

The crossing over the valley is best viewed from surrounding roads or paths since traffic flows on the motorway itself. Those wishing to see the structure should use local viewpoints or parking areas nearby.

The bridge crosses the Brenz valley at a height of 40 metres, passing over the river Brenz, the Brenzbahn railway, several roads and a 110-kV overhead power line. Its two parallel decks follow a slight curve.
