The Hardbrücke is a road bridge and important north-south connection in the Swiss city of Zürich. The bridge is 1,350 metres (4,430 ft) long, and crosses the river Limmat, the Zürich–Baden railway, and several streets. In crossing the river, the Hardbrücke forms an upper level to the lower level Wipkingerbrücke road bridge. Between the river and rail crossings, several exit and entrance ramps link the bridge to the streets below.
Construction of the bridge commenced in 1969 and it was opened in 1972. The bridge underwent a major refurbishment between 2009 and 2011.
At the point at which the bridge crosses the railway tracks, it provides access to Zürich Hardbrücke railway station below on the Zürich S-Bahn. Zürich trolleybus routes 33, 72 and Zürich bus route 83, and tram route 8 serve the adjacent stop on the bridge.
