Viadukt Chemnitz, Railway bridge in Zentrum district, Chemnitz, Germany.

Viadukt Chemnitz is a steel railway bridge in the Zentrum district of Chemnitz that crosses Annaberger Street and Beckerstrasse using both truss and arch construction. It runs for roughly 275 meters and stands about 20 meters above street level.

The viaduct was built between 1901 or 1903 and 1909 for the Dresden–Werdau railway, with steel supplied by the Königin Marienhütte in Cainsdorf near Zwickau. Construction cost 1,050,999 marks, shared by the city of Chemnitz and the Royal Saxon State Railways. It originally carried four tracks; two were closed after about 20 years and more were dismantled after World War II. A planned replacement and demolition was rejected by the Eisenbahn-Bundesamt after public protests, and a full restoration was completed in September 2024.

The bridge is known locally as Viadukt Beckerbrücke, after the Beckerstraße it crosses with its seventh opening. Its riveted steelwork came from the Königin Marienhütte in Cainsdorf near Zwickau, and the city and the Royal Saxon State Railways shared the 1,050,999 Mark cost. Residents and heritage experts successfully opposed demolition, and since 2022 the 275-metre structure has been restored with sandblasted and recoated historic girders.

The viaduct carries the Dresden–Werdau line over Annaberger Straße (B 95), the Chemnitz river and Beckerstraße, so it is seen from below rather than walked across. The 275-metre structure has twelve openings; the seventh, a steel arch, spans Beckerstraße. Restoration finished in September 2024, and Chemnitz announced a new, better-integrated access to the Stadtpark with improved foot and cycle paths.

The riveted structure has twelve openings, with two arch segments and several plate-girder spans. Plans to demolish it were rejected by the Federal Railway Office after protests, and restoration finished in September 2024.
