Tonkin Highway – Collier Road to Dunreath Drive, including Guildford Road interchange

Under constructionUnder Construction

Upgrading the highway with additional lanes, new interchanges, bridges and a shared path between Collier Road and Dunreath Drive.

What's Happening 

 Great Eastern Highway new loop ramps

The next stage of the Great Eastern Highway upgrade is about to start. In mid-June we will be activating the new loop ramp from Great Eastern Highway to Tonkin Highway northbound. The existing northbound on-ramp will be temporarily closed. Traffic will also be reduced to two lanes in each direction between Lyall Street and Boulder Street.

Please plan ahead if you are using Great Eastern Highway in the area.

 Traffic changes in place between Dunreath Drive and Guildford Road

We have switched traffic from Great Eastern Highway to Tonkin Highway northbound onto the new Redcliffe Bridge. Until late-June, traffic on the Tonkin Highway main carriageway will not be able to exit at Guildford Road while we complete pavement works adjacent to the ramp.

We continue with asphalt works and will soon see all traffic travelling on Tonkin Highway northbound switched onto the new Redcliffe Bridge.

 Tonkin Highway between Collier Road and Benara Road

By late June Tonkin Highway between Collier Road and Benara Road will return to three lanes in each direction. The speed will remain 80 km/h as there are ongoing construction works for the Morley-Ellenbrook Line.

While it might appear that there are no works occurring, the speed limit remains at 80 km/h to allow trucks and workers to enter and exit the median work area safely.

You can find more information about these, and other upcoming works, in the latest construction update.
