S-Bahn-Brücke Hanau-Steinheim, Railway bridge in Hanau, Germany

The S-Bahn-Brücke Hanau-Steinheim is the westernmost of three parallel Main crossings at kilometre 56.370, carrying the single-track Frankfurt Schlachthof–Hanau line. Its 160.2-metre steel arch span weighs 1,450 tonnes; the two arches lean 8° from vertical and merge over a 62-metre central section. A three-field prestressed concrete approach bridge (spans 25.175, 25.175 and 27.319 metres) stands on the left bank.

A bridge has crossed the Main at this location since 1873, making it the first permanent passage after a gap of over 1000 years. The current S-Bahn bridge was built in the 1990s as a modern addition designed specifically for rail traffic.

The S-Bahn bridge carries the S8 and S9 lines, whose Steinheim stop at the southwest end replaced the former Steinheim (Main) station. From 1909 to 1933 the Hanau tram line 3 also ran over the older road bridge here, from the Markt to Steinheim Obertor.

The S-Bahn bridge carries only the single-track line to Hanau Hauptbahnhof, so it cannot be walked; the parallel road bridge of the B 43/B 45 has foot and cycle paths on both sides and gives the closest view. The S8 and S9 stop at Steinheim (Main) on the southwest bank.

Workers discovered a Neolithic dugout canoe during construction in the 1990s near the riverbank at this site. The finding shows that people have been crossing at this location for thousands of years.
