West Gate Tunnel Project

Melbourne, VIC

Project Description

Massive West Gate Tunnel Project in VIC reaches new milestone

The West Gate Tunnel Project, which commenced construction in 2020, is a major infrastructure initiative designed to improve Melbourne’s road network by easing congestion and enhancing connectivity. The project features a 6.5-kilometer toll road, including 2.8 kilometers of twin tunnels running beneath the Yarra River. These tunnels will provide an alternative to the heavily congested West Gate Bridge, reducing reliance on the existing structure and offering a more efficient route for commuters and freight transport.

In addition to the tunnels, the project includes widening the West Gate Freeway, constructing new bridges, and creating improved access to key industrial and commercial hubs. A key objective is to improve freight efficiency, particularly for trucks traveling to and from the Port of Melbourne, by reducing travel times and minimising bottlenecks. The upgraded road network is expected to enhance overall road safety, support economic growth, and provide new cycling and pedestrian paths, contributing to a more sustainable transport system.

With a total project value of $11 billion, the West Gate Tunnel Project is a significant investment in Melbourne’s future transport infrastructure. The construction is being carried out by CPB Contractors and John Holland, with CPB Contractors responsible for the $3.3 billion tunnel section. Once completed, the project is expected to significantly cut travel times, ease congestion on local roads, and improve air quality by reducing traffic-related pollution in residential areas.
