Behind the scenes tour of the West Gate Tunnel Project’s westbound exit tunnel portal

Building Description

If you’ve travelled out west on the West Gate Freeway, you may be wondering what’s happening behind the screens near Brooklyn as you pass over the Newport Rail Line.

You may be surprised to know that crews have dug a massive hole 30-metres deep next to the hustle and bustle of 200,000+ daily motorists travelling on the Freeway. The hole is in fact one of three West Gate Tunnel portal sites!

Known as the westbound exit portal, crews have worked through some very complex construction challenges to get this impressive site ready to receive a 15.6 metre tall tunnel boring machine (TBM) after it completes its 4-kilometre journey.

Importantly, the westbound exit portal – complete with world-class architecture – will ultimately provide motorists a quicker and more direct trip to Melbourne’s west via the West Gate Tunnel.

Join West Gate Tunnel Project engineers, Desi and Tobias, to learn about the engineering, machinery, technology and people building what will be an iconic and historic piece of infrastructure for Melbourne.

What's On
