Cars and trucks will enter the citybound tunnel from the West Gate Freeway just west of Williamstown Road and exit near the Maribyrnong River. To travel west, cars and trucks will enter the tunnel near the Maribyrnong River and exit at the West Gate Freeway just east of Millers Road.
The tunnels are being built using 2 tunnel boring machines (TBMs), with minimal impact to the community and businesses, while work happens below ground.
The project will deliver:
Tunnel safety features for smooth operation of the tunnel, including automatic detection for over-height trucks, fire systems and emergency access and exits.
The start and end of each tunnel is being built using the ‘cut and cover’ method. This involves excavating a trench then covering it with a concrete deck to form a roof. This is where the tunnel boring machines (TBMs) start and end their journey.
The Aboriginal culture and heritage of Melbourne’s west is reflected in the design of the tunnel portals, which has been inspired by the form of traditional nets and traps used to catch eels.
Work has started on a purpose-built facility at Hi-Quality Group’s Sunbury Eco-Hub that will manage and dispose of soil excavated by the tunnel boring machines on the West Gate Tunnel Project. Learn how we manage rock and soil from this project on our Tunnelling and soil management webpage.
