Symmons Plains to south of Perth

Symmons Plains to south of Perth

The works

This project will improve the safety of the section of road between Symmons Plains and south of Perth by implementing a range of safety measures including a flexible safety barrier, curve improvements, safe turning facilities, and improvements to accessibility.

To reduce impact on the hawthorn hedged landscape to the west, the highway will be widened on the eastern side. Trees and other vegetation will be planted in collaboration with landowners to replace those removed as part of the works.

Current situation

The contract for the works was awarded to Andrew Walter Constructions.
