The Port Bouvard Bridge

The Port Bouvard Bridge over the Dawesville Channel 100 km south of Perth was built by Thiess Contractors and opened to traffic in September 1993, two months ahead of schedule. The bridge was incrementally launched, and the design contained many features which facilitated meeting the weekly cycle which was achieved for all launches. It has a number of unusual design aspects which combined to produce an easily constructible and maintainable bridge. The most striking of these is the very large open cross-section, which utilises a pair of 3.1 metre deep I-beams to support a 19 metre wide deck. With a length of 360 metres, this is the largest bridge designed in Western Australia since the introduction of the AUSTROADS Bridge Code, which proved to have some unexpected influences on the design. The substructure columns are up to 19 metres high and the pilecaps were specially designed to resist vessel impact. The bridge also has special features for services access, maintenance, and pedestrian facilities.
