Melbourne
mega-project

The numerous bridge structures of the once-in-a-generation West Gate Tunnel project in Melbourne are being equipped with more than a thousand mageba bridge bearings and over a thousand meters of our expansion joint.

The West Gate Tunnel Project in Melbourne is currently one of Australia’s largest infrastructure projects, centered on the construction of a pair of three-lane road tunnels, each 6.8 kilometers long. The project also includes the widening and strengthening of many existing bridges and the construction of numerous new structures – involving a remarkable 22 kilometers of bridge structures in total. Many of these bridges and elevated highways are being constructed with mageba bearings and expansion joints, with our local team having already designed and supplied 750 LASTO®BLOCK elastomeric bearings and 329 RESTON®POT bearings of the HP (high-performance) variety, with 1070 linear meters of TENSA®SEAL expansion joint also supplied. The required testing of the bearings was performed in mageba’s NATA-accredited lab in Sydney and in the company’s NATA ILAC MRA facility in Asia, confirming the quality and performance that is to be expected from mageba bearings at any time – and is always demanded by an extraordinary project such as this.

The West Gate Tunnel project in Melbourne is an enormous undertaking centered on the construction of two three-lane road tunnels, each 6.8 km long

The project also involves the construction of numerous bridges and long stretches of elevated highway which require over a thousand bearings to support their superstructures

For this project, mageba designed and manufactured 750 LASTO®BLOCK elastomeric bridge bearings and 329 RESTON®POT bearings of the HP (“high performance”) type

Testing of the bridge bearings was performed in mageba’s NATA lab in Sydney (for loads of up to 33,000 kN) and in the company’s NATA ILAC MRA facility in Asia (for loads of up to 60,000 kN)

The RESTON®POT bearings were designed for vertical loads of up to 33,000 kN and horizontal forces of up to 4,500 kN
