Project Overview

Located on the Monaro Highway between Canberra Avenue and Hindmarsh Drive, Bridge 3161 spans the Jerrabomberra Creek waterway, facilitating approximately 43,000 vehicle movements per day. As part of the Australian Government’s $300 million dollar “Bridges Renewal Programme” funding was allocated for strengthening of Bridge 3161 to improve public safety and provide greater capacity for commercial transport.

The scope of works included; jacking of the bridge superstructure to replace bridge bearings, carbon fibre strengthening of girders, stormwater drainage remediation and clearing of debris from the congested downstream waterway. Complex displayed a number of innovative approaches during construction, jacking the bridge superstructure using a unique incremental jacking/propping methodology, and drastically reducing environmental and financial impacts of the project by processing, blending and reusing materials from the waterway to restore the adjacent landscape.
