As part of the largest transport infrastructure project in northern Victoria, we’re building a second Murray River crossing to connect Echuca and Moama to make it quicker and easier for you to travel across the Campaspe and Murray rivers.
The new Echuca-Moama river crossing is made up of two new bridges over the Murray and Campaspe rivers, and two smaller flood relief bridges. We’ve designed the bridges over the Murray and Campaspe Rivers to integrate seamlessly with the surrounding natural environment. We’ll also install noise walls to help reduce traffic noise for nearby properties.
The new Murray River crossing will measure a whopping 622 metres across the floodplain and will sit 15 metres above the riverbanks. The bridge will consist of 14 separate spans, measuring up to 34 metres in length. The main span over the river will be 115 metres long. The new bridge across the Campaspe River will be 293 metres long and consists of eight spans. We've used a 45-metre-long steel box girder to build the main span over the river.
For the other seven spans, we've used precast concrete super-tee beams. The steel box girder has been selected for the main span across the Campaspe River as it’s 45-metre length is too long for conventional super-tee beams. We'll also build a new walking and cycling bridge, which will provide a safe and scenic journey between Echuca and Moama.
Flood relief bridges
As part of Stage 3, we’re also building two small flood relief bridges over the Murray River floodplain, one on either side of the river. These bridges will be constructed approximately 500m from each riverbank. They will provide additional hydraulic capacity during large floods, ensuring upstream flood levels are controlled.
Building the bridge across the Murray River.
Concrete piles are hammered into the ground at each riverbank, to depths of approximately 35 metres. The piles help to create a strong foundation for the bridge piers.
Form travellers are then positioned on top of the bridge piers. Form travellers are concrete moulds that move along rails to build the main span of the bridge.
The form travellers move along in five metre lengths, progressively building the bridge over the Murray River until the main span meets in the middle.
Building the bridge across the Campaspe River.
Concrete piles are hammered into the ground to depths of approximately 35 metres using a piling rig to create a strong foundation. Thick concrete slabs (known as pile caps) are then installed across the piles to link them.
The bridge piers are then built using specialised braced forms and steel reinforced cages. Concrete is then poured into the reinforced cages.
Concrete beams are then installed on top of the bridge piers. Once the beams are in place, a concrete slab is cast on top to create the bridge deck.
While the bridge deck is being built, we also install drainage, barriers, kerbing and lay asphalt to create the surface of the new road. The final touch involves marking the new road with lines to divide the traffic lanes.
