Project Overview

The Project involves the construction of a Cycle and Pedestrian overpass over the western Freeway linking Mt Coot-tha Road to the Western Freeway Cycleway. The overpass consisted of a fifteen span composite bridge with a concrete substructure and steel superstructure with a cast insitu deck and kerbs.  It also included approaches which involved block retaining walls, embankment, drainage, fencing and concrete paths.

Project Characteristics

• Traffic management involving Multi Staging of works including Night works on the Western Freeway intersection with a traffic count in excess of 75,000 vehicle per day
• The two longer spans over the Western Freeway required dual lifts. To maintain traffic flow during these operations, temporary crossovers were constructed and traffic in contra-flow was required.
• Cohesive interaction and communication with project Partners to deliver a successful project within extremely tight timeframes.
• Innovation and development of working at heights barrier system to enable works at heights to progress whilst ensuring the safety of the passing vehicles and workers below.
• 3 metre suspended concrete slab over the Western Freeway  using sacrificial Bondek Formwork System

Key Project Outcomes

• This project evolved with significant Early Contractor Involvement and ensured that consultation with the client stretching from the design stages through to the completion of construction was delivered using a “best for Project” approach.
