Haiger Bridge, Road girder bridge in Hesse, Germany.

The Dilltalbrücke Haiger is a composite girder bridge carrying the A45 motorway over the Dill river between Haiger and the Rodenbach district in Hesse. Its two separate superstructures of differing widths each consist of a single-cell composite hollow box girder with a cast-in-place concrete deck slab that is partly transversely prestressed. The current bridge has 13 spans ranging from 45 to 85 metres.

The first bridge at this site was built between 1965 and 1968 by Backhaus and Kögel GmbH as a 15-span plate-girder structure 801 metres long, with spans of 53.40 metres each. It carried the A45 until 2000, when it was replaced. The current bridge, built by Heilit-Woerner Bau-AG of Munich, opened to traffic in 2003.

The bridge carries the A45 motorway over the Dill between Haiger and the Rodenbach district. Its name comes from the Dill valley it crosses; the structure itself has no footpath or viewing point, so it is seen only in passing from the motorway.

The bridge is open to vehicle traffic year-round and provides a main crossing route through the valley. From the crossing, you can see the surrounding landscape and the valley floor beneath the structure.

The 1965–1968 predecessor was a 15-span plate-girder bridge 801 m long, with each span measuring 53.40 m; it was built by Backhaus and Kögel GmbH and demolished in 2000 for the replacement.
