(Image: Transport for NSW) The Warringah Freeway Upgrade Joint Venture partners, CPB Contractors and DT Infrastructure, have won the Collaboration for Project Excellence category at the 2025-26 Consult Australia Awards for Excellence. The annual awards acknowledge effective partnerships, shared goals and outcomes, innovation through collaboration and positive impact. Commencing in 2021, the Warringah Freeway Upgrade has upgraded the freeway from its original construction in the 1960s to add extra lane capacity for the new Western Harbour Tunnel entries and exits. Improvements to the freeway will also make it safer and easier to use, more efficient and reliable for the benefit of all road users, including public transport users. Regarded as one of Australia’s most complex road upgrades, the project team has optimised available nightly lane closures to reduce the impact of works for the 250,000 motorists who use the freeway each day.
