Tonkin Gap Project and Associated Works
Tonkin Highway – Collier Road to Dunreath Drive, including Guildford Road interchange
Tonkin Highway will be transformed to deliver a high standard, north-south transport link from Muchea to Mundijong.
The Tonkin Gap Project will address the current bottleneck where the 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.
The preliminary concept includes:
- Widening Tonkin Highway to provide new lanes in each direction from Dunreath Drive to Collier Road, as well as new roads linking Guildford Road and Great Eastern Highway
- New bridges over the Swan River, Dunstone Road, Guildford Road, Railway Parade
- New fully grade-separated Principal Shared Path (PSP) on the western side of Tonkin Highway from north of Guildford Road interchange to approximately Stanton Road with local connections
- Noise walls
- Upgraded lighting and intelligent transport systems (ITS) infrastructure
