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 was replaced with fibre reinforced polymer and the timber footpath with aluminium. [6] [7]
The bridge is listed on the South Australian Heritage Register. [8]
