Delivering Oversize Concrete Components for One of Melbourne’s Largest Infrastructure Builds
Ares Group played a major role in the West Gate Tunnel Project (WGTP) by transporting thousands of oversized precast concrete components from regional manufacturing sites into Melbourne. Over four years, the team moved around 2,000 units, including crossheads, matchcast segments, planks, capitals, and Super Tees.

Key Statistics

72
Crossheads

These massive concrete elements sit on top of columns and support the bridge deck above.

1400
Match Cast

Coming in sets of 17, each segment had to be installed by a specialised launching gantry crane over Footscray Rd.

220
Planks

The only components not coming from Benalla, the bridge planks measured up to 25m in length and were transported from Echuca.

128
Super Tees

These precast bridge beams weighed in at 80 tons and are designed to carry the concrete road deck above.

Project Challenges

Four precast component types, four very different heavy haulage problems to solve.

Colossal crossheads

Transporting 72 bridge crossheads, each weighing over 140 tonnes, required a fully engineered logistics solution. Ares designed custom transport frames and modified heavy haul trailer configurations to lower the centre of gravity and evenly distribute the load. Night-time convoys, supported by accredited pilot vehicles, VMS boards and controlled speeds as low as 5 km/h over bridges and culverts, ensured the safe and efficient delivery of the heaviest oversized loads Ares has transported.

The Super Tee bridge beams combined serious weight with awkward length, up to 80 tonnes and 24 metres. No standard trailer could handle both at once. We ran a four-axle low loader at the front and a jinker trailer at the rear, which solved the weight and the dimensions in one configuration.
We delivered the transport and offloading solution for 17 match cast segments, each weighing up to 80 tonnes (1,400+ tonnes total).
Bespoke standing frame and offloading systems eliminated the need for cranes, minimised weather delays and downtime, and maximised turnaround efficiency through safe, streamlined storage and handling operations.
The bridge planks were the only components not coming from Benalla. Made in Echuca and up to 25 metres long, they took a winding route through Shepparton and Seymour into Melbourne, without a direct Hume Highway link. Our extendable trailers handled them easily. They are built to carry 70-metre wind turbine blades, so 25-metre planks were never going to be a stretch.
Results

Over four years, Ares delivered close to 2,000 oversize components for the West Gate Tunnel Project, now forming the elevated road over Footscray Road plus new ramps, bridges and flyovers across the site.

 
Every load was delivered safely, including the heaviest and most awkward in Ares’ history, and CPB John Holland’s logistics lead called the team innovative and highly professional, singling out the safe execution of every task.
