Tonkin Gap Project and Associated Works

Overview

As part of the Tonkin Gap Alliance, BMD in alliance with Main Roads Western Australia, Public Transport Authority, Georgiou Group, WA Limestone, BG&E and GHD – is delivering the $400 million Tonkin Gap project.

As one of the most significant infrastructure projects in Western Australia’s history, the Perth Tonkin Gap Project has already generated significant buzz and anticipation. Commenced in 2020, the project will reduce congestion, improve transport efficiency, and create new opportunities for commuters when complete.

The project is a game-changer, setting out to transform the way people move in and around the bustling city of Perth, and provide a blueprint for other cities looking to modernise their transport systems.

The Tonkin Gap Project will address the current bottleneck where Tonkin Highway reduces from three lanes to two lanes in Bayswater and Redcliffe, significantly reducing travel times and improving safety. We will also be making improvements to access and connectivity for road users, pedestrians and cyclists in the project area. 

The Associated Works will provide rail-enabling works for the METRONET Morley-Ellenbrook Line along Tonkin Highway, including underpasses and dive structures, to enable trains to enter and travel along the median of Tonkin Highway then exit in Malaga. Road and bus bridges will be built at Broun Avenue to provide access to the future Morley Station.

Scope

Scope of works for the project include:

• additional traffic lanes on Tonkin Highway in each direction between Collier Road and Dunreath Drive
• new bridges over the Swan River, Guildford Road, Railway Parade, the Midland Line railway and Dunstone Road
• upgrades to the Guildford Road and Great Eastern Highway interchanges
• a Principal Shared Path with bridges, underpasses and local connections for cyclists and pedestrians
• noise walls, lighting and amenity improvements
• New underpasses and dive structures for trains to enter and exit Tonkin Highway median at Bayswater and Malaga
• Remove and rebuild Broun Avenue bridge as an integrated road and bus bridge, which will provide access to the new Morley Station
• New rail bridges at Morley Drive
