Birkenhead Bridge

Birkenhead Bridge is a bascule bridge crossing the Port River with a double-leaf mechanism that raises to let ships pass underneath. The structure stretches across the waterway and links the suburbs of Birkenhead and Port Adelaide by road.

The bridge opened in 1940, replacing ferry services that had transported people across the river since the 1840s. This project became a turning point for connecting the growing communities on both sides of the waterway.

The structure stands as an example of early Australian industrial engineering, demonstrating the advancement of transportation infrastructure in South Australia.

The bridge carries regular traffic between the two suburbs and has separate paths for pedestrians and cyclists to use safely. The roadway lifts periodically to allow water traffic to pass, so check for any raised-bridge notices before planning your crossing.

The structure was originally designed with dedicated lanes for trolleybuses, making it one of only a handful of bascule bridges worldwide built for this specific transit mode. This unusual feature shows how engineers planned for diverse transportation needs in that era.
