An innovative bridge solution saw us secure the design and delivery of the recently completed Echuca Moama Bridge project for the Victorian and NSW state governments.
To win the project our tender team 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.
