Dorenbachviadukt, Reinforced concrete road bridge in Basel-Stadt, Switzerland

The Dorenbachviadukt is a reinforced concrete road bridge linking the Gundeldingen and Bachletten districts of Basel, just south of the zoo near the Binningen border. It is one of three large viaducts crossing the Birsig valley in the city. The Dorenbach stream, which gives the bridge its name, flows into the Birsig just south of the structure.

The Dorenbachviadukt was built between 1932 and 1934 to plans by Robert Gsell-Heldt and opened on 4 August 1934. In 1985 it was renovated, and tram service to Binningen was suspended for the whole of that year; it resumed afterwards.

The bridge serves as a daily crossing point for residents moving between two residential districts. You will see pedestrians and cyclists using it as part of their everyday routes through the city.

The best way to experience this bridge is on foot or by bicycle, as you will see its structure and surroundings most clearly from the top. The areas beneath the bridge are also accessible if you prefer a different viewpoint.

The bridge opened on 4 August 1934. In 1985 it was renovated, and for that whole year tram service to Binningen was suspended; trams resumed once the work was finished. The Dorenbach stream, which gives the bridge its name, joins the Birsig just south of the bridge.
