Key Facts

Southern Gateway Alliance (SGA) was formed in September 2006 to design, construct and deliver the NPBH, which is one of Western Australia’s most significant infrastructure projects.

To meet this challenge, three of the industry’s leading companies - Leighton Contractors, WA Limestone and GHD have come together with Main Roads Western Australia (Main Roads), our State road agency.

Construction commenced in December 2006 and the full length of the New Perth Bunbury Highway is scheduled to open to traffic several months before the 31 December 2009 contract end date. To achieve this timeframe, construction is occurring on several sections of the alignment concurrently.

To date, the project team has worked more than 3.5 million man hours without a lost time injury.

At our peak, the haulage operations have involved a fleet of some 200 trucks, hauling some 50,000 tonnes per day and travelling a combined distance of 50,000 kilometres per day (or 1.2 times the distance around the equator).

At the project’s peak, there were approximately 800 pieces of plant and machinery approved to operate on site.

Since the project commenced SGA has awarded 328 contracts with 36% to local companies representing a $92 million injection into the local econamy.
