An innovative bridge solution saw McConnell Dowell secure the design and delivery of this important new river crossing for the Victorian and NSW state governments.
To secure the project McConnell Dowell challenged the design (an extradosed bridge) and developed an alternate main bridge solution which included a number of enhancements to streamline construction and reduce costs, including:
A cantilevered 115m main span box-girder bridge solution that avoided temporary or permanent marine-based structures. This solution also reduces maintenance, minimising the need to access the waterway and waterflows.
The Murray River bridge cross-section and vertical alignment was re-engineered to maximise longitudinal fall - optimising drainage performance thereby reducing drainage infrastructure.
The gradient of the road was increased while maintaining river span clearances. This has enabled the removal of redundant clearances at abutments and reduced earthworks volumes.
The McConnell Dowell team have also explored ways to benefit the local community during construction. For example:
The team has strengthened bonds with local schools located near the project, holding regular information sessions, site tours and even hosting a jobs workshop to promote construction as a career.
During the pre-COVID-19 period, the team was able to connect with residents through door-knocking and small community meetings. As a very personalised approach, in a tight-knit community, it enabled the communications and engagement team to produce a comprehensive contact list of residents and businesses that could potentially be affected by works. This streamlined the communications once the pandemic hit.
- From a social inclusion perspective, the team is engaging a local disability services provider for site maintenance, caretaker duties and cleaning. A total of 14 indigenous owned businesses have also been engaged on the project.
