Seiterswegbrücke, bridge in Germany

The Seiterswegbrücke is a single-span segmental arch bridge carrying a paved path over the Odenwaldbahn railway in eastern Darmstadt. Built of sandstone with stone parapets on both sides, it has a span of roughly 10 metres and a deck now surfaced with paving stones after the asphalt was removed in the 2016–2017 restoration.

The bridge was built in 1872 and remains the oldest bridge still standing in Darmstadt. After decades of use, it was closed to motor vehicles in 2014 and underwent major repairs between 2016 and 2017.

The bridge connects Darmstadt's city center with the Mathildenhöhe and Rosenhöhe neighborhoods, used daily by residents walking and cycling between these areas. Its simple stone structure with railings from the 1870s continues to shape how people move through and perceive this part of the city.

Since June 2014 the bridge has been closed to cars and serves only pedestrians and cyclists. Drivers cross the Odenwaldbahn at a level crossing south of the bridge or via the Dieburger Straße bridge to the north. The deck was repaved with cobblestones after the 2016–2017 restoration.

The bridge's deck was once covered with about 30 cm of asphalt to widen the roadway; the 2016-2017 restoration removed it entirely and replaced it with paving stones, returning the surface to its original state. The parapet must reach 1.30 m for cyclists.
