The Birkenhead Bridge is a bascule bridge in Adelaide, Australia that crosses the Port River.

In February 1938, the Government of South Australia awarded a contract to Adelaide Construction to build a bridge across the Port River from Birkenhead to Port Adelaide, with Perry Engineering contracted to supply the steelwork.[1] The bridge was opened on 14 December 1940 by Governor Malcolm Barclay-Harvey.[2][3] It was one of only four bascule bridges in the world adapted for use by trolleybuses.[4]

In 2014, two of the four road lanes were converted into pedestrian and bike paths.[5] In 2020, the timber road deck has been replaced with fibre reinforced polymer and the timber footpath with aluminium.[6]

The bridge is listed on the South Australian Heritage Register.[7]
