Project overview

Located on State Highway 8 near Lawrence, the new 195-metre-long two-lane bridge crosses the Clutha River (Mata-Au) and replaces the original 1887 single-lane bridge. After more than a century of service, the historic bridge had become unsuitable for modern traffic demands. It will now enjoy a second life, forming part of the Clutha Gold Cycle Trail as a walking and cycling link.

The project, led by HEB Construction, has been a significant undertaking for the region. Allied Concrete’s Balclutha and Alexandra branches worked together to ensure a reliable and consistent concrete supply across the project’s duration. With the site presenting logistical challenges, careful coordination was crucial.

Concrete Supply

In total, Allied Concrete supplied 1,914m³ of concrete, with a variety of mixes tailored to the bridge’s unique technical requirements, including self-compacting concrete and mixes designed for freeze-thaw durability. The project also involved extensive on-site and plant testing to ensure compliance with stringent standards.

Work throughout 2023 included daily barrier pours using 50MPa self-compacting concrete, expansion joint pours, and the construction of connecting cycleway paths to link with the Millennium Track and Beaumont Hotel. Approximately 200m³ of concrete has been poured into the cycleways, helping enhance the region’s recreational infrastructure.

Allied Concrete is proud to support infrastructure projects that serve local communities and future generations. We acknowledge the incredible teamwork between our branches and thank HEB Construction for the opportunity to be part of this important project.
