Concrete ServicesCivil Construction & Road Maintenance
The City of Kalgoorlie Boulder engaged Dowsing Group to construct a new single-lane, four-leg roundabout at the intersection of Wilson Street and Macdonald Street, Kalgoorlie. The project was funded under the State Government Black Spot Program, targeting safety improvements at a known hazardous intersection within the Kalgoorlie community.

The intersection serves as a key traffic corridor following development of the nearby Coles complex and shopping precinct and is used daily by a wide range of road users.

Works were delivered by Dowsing’s local Kalgoorlie team, with civil engineering support from our Perth office, ensuring local knowledge and responsiveness throughout the construction program.
