West Gate Tunnel

Witney Jimenez — Mon, 15 Dec 2025 06:32:49 +0000

A Full-Circle Moment on One of Victoria’s Biggest Projects

More than 26 years ago, Colin Calder, Pushpa Nadanapatham, Michael Eager and Van Bardzamian worked together in Melbourne on the original Western Link (CityLink) project; the last major corridor linking Melbourne’s west to the CBD and north. Two decades later, the team has reunited at CJC, returning once again to the very same transport spine they helped shape in the 1990s.

Now, Colin and team members across CJC, have delivered the next generation of that network: the West Gate Tunnel project, one of the most complex infrastructure undertakings in Victoria’s history.

Strengthening a City-Shaping Project

The West Gate Tunnel will transform how Melbourne moves, providing a vital second river crossing, easing pressure on the West Gate Bridge, and removing 9,000 trucks a day from inner-west streets. With twin tunnels, major freeway upgrades, and a new elevated roadway above Footscray Road, it is a once-in-a-generation upgrade to the state’s transport network.

CJC was deeply embedded across the project, delivering a blend of project leadership, commercial strength, and construction oversight on behalf of Transurban. Our team managed key interfaces, supported milestone delivery, led contract and commercial processes, and provided on-the-ground supervision across complex surface works and bridge packages.

This included coordinating construction on Melbourne’s busiest traffic corridors, overseeing major steel erection activities, managing stakeholder engagement, and driving the Completion Obligations process across a multi-party PPP environment.

6.8 km twin tunnels beneath Yarraville.
9,000 trucks removed from residential streets every day.
46,000 tonnes of steel used across the bridges and elevated structures.
450 tonnes this individual girder was the project’s heaviest lift. The largest girder was 95 m.
17 km of continuous upgraded transport corridors.

Easing Sydney’s Congestion M4 Smart Motorway Stage 3

Jaweria Saeed — Fri, 21 Aug 2020 06:25:00 +0000

Scope

The NSW Government is investing $470 million to build the M4 Smart Motorway project which includes a 35km upgrade along the M4 Motorway from Lapstone to Mays Hill. When complete, the project will provide a tailored technology solution to create a better travelling experience for motorists and a more consistent journey.

Smart Motorways use complementary technologies to monitor traffic conditions, manage congestion and respond to incidents in real-time. The M4 Smart Motorway will introduce a smarter way of travelling by using real-time information, communication and traffic management tools to provide motorists with a safer, smoother and more reliable journey.

The M4 Smart Motorway will be the first Smart Motorway in NSW and brings together intelligent traffic technologies to maximise the performance of the motorway.

CJC role

CJC was engaged by RMS (now TfNSW) in the role of Project Manager. Our role was responsible for managing the construction, commissioning and integration of the Intelligent Transport System (ITS) network for the Smart Motorway. Tasks included construction management of site activities, assessment of claims and variations and liaison with stakeholders on the testing and commissioning of the ITS network.
