Wilhelm-Heinrich-Brücke, Road bridge in Saarbrücken, Germany.

The Wilhelm-Heinrich-Brücke is a road bridge over the Saar in Saarbrücken, linking St. Johann with Alt-Saarbrücken. Since its 2018 renovation it carries one bicycle lane per direction, partly in the middle of the roadway, and one motor-vehicle lane was removed in each direction for them.

The present bridge, dedicated to William Henry of Nassau-Saarbrücken, was inaugurated in 1961 by Franz-Josef Röder. Its predecessor, the Kaiser-Friedrich-Brücke, a steel arch built in 1910, was blown up in 1945 after war damage. During the interim, pedestrians used the Kummersteg, a 4-metre-wide steel arch footbridge; after the new bridge opened, it was dismantled in early 1962 and later re-erected as the Freundschaftsbrücke between Kleinblittersdorf and Grosbliederstroff.

The bridge is named after Wilhelm Heinrich, Count of Nassau-Saarbrücken, who ruled in the 18th century. His name also appears on the nearby Wilhelm-Heinrich-Straße, and the dedication ties the crossing to the principality that once governed Saarbrücken.

The bridge underwent major renovations in 2018 that included new bicycle paths alongside the roadway. The dedicated walking and cycling infrastructure makes it easy to cross as a pedestrian or cyclist.
