Mount Henry Bridge, Railway and road bridge system in Perth, Australia
Mount Henry Bridge is a pair of parallel bridges carrying the Kwinana Freeway and Mandurah line across the Canning River. The original 1982 bridge is a nine-span post-tensioned concrete box girder, 660 metres long and 28.8 metres wide, with shared paths cantilevered underneath. The 2006 bridge overlaps it without touching, so the two appear as one structure.
The first bridge, built by Clough and Sons for A$13.5 million, opened on 9 May 1982 as part of a 6.5-kilometre Kwinana Freeway extension. A second bridge, built by Leighton Contractors for $23 million, opened on 22–23 January 2006; the Mandurah line began running on 23 December 2007. The bridge was added to the State Register of Heritage Places in 2026.
The bridge shows how the river divides and connects the city. People use the pathways alongside it to cross from one shore to the other while enjoying views of the water.
Visitors can use the pedestrian and bicycle paths on either side to cross the river and explore the area. The best time to visit is early morning or late afternoon when light is optimal and traffic is lighter.
The second bridge was built by Leighton Contractors, whose alternative proposal to build a separate span west of the existing bridge instead of widening it saved $17 million and reduced traffic disruption. Because the 76-metre spans were too long for incremental launching, temporary piers were placed between the permanent ones during construction.
