Mount Henry Bridge

About

The Mount Henry Bridge is a pair of parallel bridges which carry the Kwinana Freeway and Mandurah line across the Canning River in Perth, Western Australia. At 660 metres (2, 170 ft) long, the Mount Henry Bridge is the longest bridge in Western Australia. The first bridge opened in 1982 and carries the southbound freeway carriageway and both tracks for the Mandurah line. The second bridge opened in 2006 and carries the northbound freeway carriageway. The first Mount Henry Bridge was built as part of an extension of the Kwinana Freeway from Canning Highway to South Street. Construction started in June 1979 and it opened to traffic on 9 May 1982. It was built by Clough and Sons for A$13.5 million. The second Mount Henry Bridge was built as part of the construction of the Mandurah line. It was originally planned for extra lanes to be added to both sides of the bridge and for the railway to go in the middle of the bridge, but this was changed so that a new bridge would be built on the western side of the existing bridge, and that the Mandurah line would go on the original bridge, reducing costs. Construction began in May 2004 and the new bridge opened to traffic on 22–23 January 2006. The Mandurah line opened on 23 December 2007. The new bridge was constructed by Leighton Contractors for $23 million. In 2026, the Mount Henry Bridge was added to the State Register of Heritage Places.
