Tonkin Highway Grade Separations

Funding Required: $140,000,000

Funding Purpose: Initially fund grade separations for Mundijong Road and Thomas Road intersection.

There are a limited number of grade separations that have been included in the State & Federal budget at this time for the extension of Tonkin Highway. It has been envisaged that the roundabout type intersections be used where grade separations are not utilised. Current locations of grade separations includes Bishop Road which is catering for the Perth to Bunbury rail line and other future rail realignment upgrades.

The current scope does not make provisions for grade separations at Thomas Road, Orton Road, Mundijong Road and South Western Highway. The $140 million requested is to initially fund grade separations for Mundijong Road and Thomas Road intersections.​
