Kaiserlei Bridge, Steel arch bridge in Offenbach am Main, Germany.

The Kaiserlei Bridge is a steel arch bridge spanning the Main River and carries the Bundesautobahn 661 across it. The structure extends roughly 220 meters and connects areas on both sides of the waterway.

Completed in 1964, this bridge was an important improvement to post-war transportation infrastructure between Frankfurt and Offenbach. The structure provided a more direct connection across the river between the two cities.

The bridge represents mid-20th century German engineering principles through its structural design, connecting communities on both sides of the Main River.

You can best view this structure from below or along the adjacent riverside paths, since the bridge is reserved for vehicle traffic. Access points on both riverbanks allow you to see the construction from different angles.

The bridge is part of the Route der Industriekultur Rhein-Main, a project that marks industrial heritage sites in the region. Its abutments rest on 172 piles, and the two steel tubes of each arch measure two metres in diameter with walls twenty millimetres thick.
