Vasse Bypass Road Construction

The purpose of the new Vasse Bypass project was to divert regional traffic around the new Vasse town site development. Constructed as a dual carriageway (with the ability to upgrade to four lanes) the Bypass has improved safety and amenity by removing large volumes of traffic from the town. The $12.8 million Bypass project was also completed on time and opened by Transport Minster Dean Nalder on 29 January 2016.

The Bypass begins at the intersection of the Busselton Bypass and Bussell Highway, and proceeds west around the nearby Vasse town site development, before reconnecting to the existing Bussell Highway, south west of the development.

One key reason Leeuwin Civil was selected for this project was their in-house capability to crush and screen all subbase and the basecourse materials required. This provided the Client surety in the overall delivery of the project.

Scope of Works:

• construction of 4km of new road, including 400m of dual carriageway;
• supply of all subgrade, subbase and basecourse for the 4km of new road and 400m of dual carriageway;
• reconstruction of the sections of the old highway and Vasse Yallingup Road that tie into the new road;
• construction of five new intersections with street lighting;
• construction of a new 25m-long concrete bridge over the Buayanyup Drain; and
• construction of a concrete underpass just east of the drain to facilitate safe movements under the highway for pedestrians and cyclists.

Leeuwin Civil was selected as a subcontractor to the JV for its ability to provide:

• complete wet hire package from an extensive fleet of equipment and skilled operators (e.g. scrapers, all-terrain water trucks);
• materials crushing and screening facilities and haulage including the importation and supply of 80,000t of gravel from its gravel pits.
