7159 Bridge Construction


The project is an upgrade of an existing through access trail in a former defence site, involving the demolition of an existing bridge and pipework, replacing this with a new 125 metre precast bridge, retaining walls and culverts.

The site is bordered by the Regional Park so management of fauna fencing delineation during works is a key focus for the contract. This bridge was constructed during multiple wet weather event which exceeded the 1 in 50 year flood levels.
