Nied Railway Bridge, Railway bridge in Frankfurt-Nied, Germany.

The Nied Railway Bridge is a 40-metre stone viaduct of three arches, each with a 10-metre span, carrying the Taunus Railway over the Nidda between Frankfurt Hauptbahnhof and Frankfurt-Höchst. The vaults, both river piers and the abutments are built of red sandstone blocks, and the piers rest on driven piles sunk into deeper soil layers.

The bridge was built in the 19th century as a major step forward for regional railway development and improved connections to the Taunus. This structure demonstrates how infrastructure modernization transformed commerce and people's ability to travel.

The bridge is listed as a Kulturdenkmal under the Hessian monument protection law and is part of the Route der Industriekultur Rhein-Main. Its three red sandstone arches, each 10 m wide, are best seen from the newer Nidda bridge a few metres away, which carries S-Bahn traffic.

The bridge carries the Taunus Railway over the Nidda between Frankfurt Hauptbahnhof and Frankfurt-Höchst station, in the Nied district. Since the 1928–1932 works it has had footbridges on its sides, so pedestrians can cross beside the tracks. S-Bahn trains use the newer Nidda bridge a few metres away, not this one.

The bridge was long considered Germany's oldest railway bridge still in use, but the Wurzen railway bridge on the Leipzig–Dresden line took that title: it entered regular service in September 1838, a year before the Taunus Railway. The Nied bridge has carried trains since 1839 without any change to its structural design.
