Gawler East Link Road: Link to the Future

Enhancing Gawler East’s connectivity and sustainability, the Link Road Project promises reduced travel times and a robust utility network for a thriving community.

Project Overview

The Gawler East Link Road Project, valued at $59.97 million, was a pivotal development aimed at enhancing transport infrastructure in the Gawler East urban growth area. By constructing a new 5.5 km road and upgrading existing networks, this project facilitated residential development and improved local traffic flow. In parallel, Diona was commissioned by Bardavcol to significantly upgrade the sewer and water network, ensuring it meets the rising demands of the area

Project Need

Gawler East’s rapid development and population growth necessitated a dual focus on transport and utility infrastructure. The project addresses the need for improved road access to support the area’s urban growth, while the utility upgrades by Diona are crucial for providing the necessary capacity to sustain this development, highlighting a comprehensive approach to regional enhancement.

Project Solution

Diona’s scope included the construction of 4.3 km of DN375 sewer and PVC-M water mains, complete with all associated manholes, connections, fire plugs, and valves. This extended to integrating these new systems into the existing networks, involving testing and commissioning in coordination with SA Water. Notably, the project featured the innovative suspension of sewer and water pipelines from a bridge substructure, showcasing Diona’s technical expertise and adaptive engineering solutions.
