Overview

This ATS technical tour offers a rare behind-the-scenes look at the Western Harbour Tunnel segment yard. Attendees will gain insights into precast segment design, production logistics, and site operations. The visit includes a short technical presentation, a guided site tour, and networking opportunities. Ideal for engineers, designers, and tunnelling professionals seeking practical knowledge and industry connection.

The Western Harbour Tunnel is a major infrastructure project aimed at reducing traffic congestion on key Sydney routes, including the Anzac Bridge, Sydney Harbour Bridge and Sydney Harbour Tunnel. It features 6.5 kilometres of dual three-lane tunnels extending from the Warringah Freeway in Cammeray to the WestConnex interchange at Rozelle. Stage 2 includes the construction of approximately 4.5 kilometres of tunnel from Birchgrove under Sydney Harbour to North Sydney.

Parking available: Numbers are limited. Please only register for the event if you plan on attending, no-shows will take the opportunity away from others
