Changes you need to know about at Reid and Tonkin highways

​On 12 August, the first new Reid Highway bridges over Tonkin Highway opened to traffic, as part of the $1.02 billion NorthLink WA initiative.

Traffic signals at the intersection were replaced with a temporary roundabout, approx. 500 m north-west of the traffic signals until mid-2019, eliminating one of WA’s most dangerous intersections.

The new temporary roundabout will minimise inconvenience to motorists and is expected to deliver an improvement in intersection performance.

As construction continues, new ramps in the free-flowing Reid and Tonkin Highway interchange will open progressively. This means fewer vehicles will need to use the temporary roundabout until it’s removed when NorthLink WA is finished in mid-2019.

Once complete, WA’s biggest free-flowing, freeway-to-freeway interchange will carry traffic at an average speed of 80 km/h and allow for free-flowing traffic in all directions, significantly reduce travel times and improve both safety and the driving experience for motorists.

Please travel carefully through the new roundabout.
