Girder Bridge Crossing the Agger River

Timber-Stone Hybrid Bridge in Lohmar

Description

The three-span bridge girder is attached laterally on the side of an existing bridge. It is supported by steel brackets, which are attached to the existing abutments. The two main beams are made of glulam timber, GL32c and laterally covered with larch. To adapt the bicycle and pedestrian extension to the existing concrete bridge, it has an identical steel railing. A grey glaze was applied to the lateral cladding. A special feature is the bridge decking, which is made of large slabs of natural stone (Grauwacke), and is protecting the main structure from above. Below the gaps gutters are arranged to ensure an optimal drainage of water.
