The Mandurah Estuary Bridge carries Mandurah Road over the Peel Inlet in Mandurah, Western Australia.
The Mandurah Estuary Bridge was opened on 18 October 1986 as a two lane structure with provision made for duplication in the future. In October 2023 the Georgiou Group was awarded a contract to build a parallel bridge to increase the number of lanes to four. The new bridge opened on 4 February 2026.
