The design and construction of a replacement bridge over Mordialloc Creek on the Nepean Highway is a clear example of Decmil’s ability to deliver quality structures in a high traffic environment.
Situated on the Nepean Highway, a major link between Melbourne and the Mornington Peninsula, this bridge replacement project required complex staging and traffic management to minimise the impact on the more than 41,000 vehicles that use it each day.
The initial stages of the project required the demolition and removal of the existing 37m long 4 span bridge.
A specific Demolition Management Plan was developed to address the manner in which these works would take place and ensure adequate controls were in place to manage the disruption. Through the deployment of turbidity curtains, the team was able to undertake the demolition works without compromising the creek environment below.
The new bridge provides wider access, doubling the number of traffic lanes to 4 and new road approaches. Along with removing what had been a traffic bottleneck through the addition of the new lanes, the bridge also provides upgraded facilities for both pedestrians and cyclists including pedestrian facilities on both sides of the bridge, shared pedestrian/bike paths, and wider kerb-side lanes.
The Project was completed with zero delays.
