Project Details

Gold Coast City Council engaged Alder Constructions to construct a new road bridge and associated civil infrastructure for the Hope Island community. The bridge is located adjacent to Village Square Market near the centre of Hope Island.

The bridge, canal excavations and road works were part of the final piece of flood mitigation works in the Hope Island canal. It has greatly improved the infrastructure and access to the area and has reinvigorated development within the area.

This new bridge is the last piece of infrastructure that will allow the vacant land in the area to be better utilised and developed. Construction of the bridge and associated civil infrastructure presented various challenges that were overcome by our dedicated construction team.

Ground improvements behind the embankments on both sides of the bridge were completed comprising of 300 piles. Significant changes were made to the design by the Gold Coast City Council during the construction and this added to the complicated construction that Alder Constructions undertook. However when the project was completed it was applauded and appreciated by the Council and residents alike.
