WEST GATE TUNNEL, AUSTRALIA<br />
CONNECTING<br />
TWO HALVES<br />
More than 200,000 vehicles cross the Westgate Freeway each day.<br />
Two gigantic EPB Shields (Ø 15.5 m) are creating a new chapter<br />
for Melbourne as they excavate 6 km of tunnel to link the West Gate<br />
Freeway with the Port of Melbourne and CityLink. The new<br />
West Gate Tunnel will ease traffic for 5 million Melbourne citizens.<br />
TBM Vida finished its journey in February 2023, marking the<br />
completion of the first of two tunnels.<br />
