Massive tunnel boring machine taking shape

Back to Newsfeed

Assembly is underway on the first of the two massive tunnel boring machines (TBMs) that will build the West Gate Tunnel.

It will take around 75,000 working hours to assemble the TBM – Bella – with up to 30 people per shift working around the clock. The 15.6m diameter cutter head, one of the last pieces to be assembled, will be moved into place by a 500 tonne gantry crane, one of the largest of its kind in Australia.

To reduce disruption to local business traffic as works ramp up, a footbridge for workers is now in place over Somerville Road between the project’s two major Whitehall Road construction sites. The 11-tonne, 8m high footbridge is made from Australian structural steel and was fabricated by Melbourne company, Calbah.

With major tunnelling works set to start this year, legislation will also be introduced into parliament this week that will provide the framework for the management of the road when it opens in 2022.

The legislation also enables the Government to finally deal with the issue of trucks on roads in the inner west by enshrining enforceable truck bans in law, removing 9000 trucks from these roads for good.

Fines collected from truck ban offenders will be reinvested in local transport projects and programs that benefit local communities via the Better Freight Fund, with a focus on those who may be impacted by changes in the truck numbers.

The West Gate Tunnel Bill and amendments to the CityLink Concession Deed will provide a fairer tolling regime for all for Victorians and remove historical clauses that would see Transurban compensated for State projects that divert traffic off its network.

An exposure draft of the West Gate Tunnel Bill and CityLink Concession Deed was released in 2017 when contracts were signed for the West Gate Tunnel Project, as part of a range of documents released for the project.
