Fremantle Traffic Bridge, Road bridge in Fremantle, Australia

The Fremantle Traffic Bridge is a road bridge crossing the Swan River to link North Fremantle and Fremantle with four traffic lanes. The structure spans approximately 219 meters across the water.

The current bridge replaced an earlier 1866 structure when it opened in December 1939. It was built largely from timber, which meant it was always expected to have a limited lifespan.

The 1939 timber bridge was meant to be temporary because Fremantle Harbour was expected to extend further east. It ended up carrying about 30,000 cars a day by 2016, far more than it was designed for. Calls to keep it as an elevated park were rejected, and it closed on 1 February 2026.

The replacement bridge is being built at the same location, with its supports erected around the old structure so traffic could keep using it until it closed on 1 February 2026. The old bridge was then dismantled and the new deck built in its place, with opening scheduled for 1 November 2026. The new crossing keeps the same number of traffic lanes but has wider pedestrian paths and higher clearance for boats.

Calls to keep the 1939 timber bridge for heritage reasons, including a proposal to turn it into an elevated park, were rejected because the structure was judged beyond restoration. The old bridge closed on 1 February 2026 and was dismantled to make way for the replacement.
