Project Details

Alder Constructions was awarded the contract to construct a 45m long, 3-span new road bridge and associated civil infrastructure for the Hope Island community. The bridge, canal excavations and road works were part of the final piece of flood mitigation works in the Hope Island canal.

Significant changes made to the design during the construction phase, providing a challenge for our team as they navigated the changes on an operational site. When the project was completed, it was hailed as a success by our client and the local community.

Scope of Works

45m long bridge comprising three spans.
Three traffic lanes, two cycle lanes and two footpaths.
New and relocated services included:
- underground and overhead power lines
- underground gas lines
- water (potable and recycled)
- sewer (vacuum and gravity)
Dredging of the canal removed over 20,000m³ of material.
Supported by 40 pre-cast concrete piles 30m long driven into the rock beneath the canal floor.
Traffic management and diversions via temporary side tracks to allow for construction to proceed with minimal disruptions.
Demolition of an existing roundabout and construction of two new signalised intersections.
