Morley Drive and Bath Road Roundabout Construction

Project Overview

Main Roads WA engaged Ertech to construct a new dual-lane roundabout at the intersection of Morley Drive and Bath Road. This important upgrade eases congestion, improves safety and enhances traffic flow for the 26,000 commuters who use this section of the road network daily.

As part of the works, access for cyclists and pedestrians will also be improved through the realignment of the existing shared path and the construction of median refuges on all three legs of the intersection.

This dual-lane roundabout construction includes vegetation clearing, earthworks, drainage, granular sub-base, FDA, seal, asphalt, signage, and line marking.
