en.Wedoany.com Reported - The New South Wales Government has appointed Seymour Whyte to deliver the new Mitchells Causeway crossing, paving the way for major construction to begin in July and the reopening of the Great Western Highway at Victoria Pass in the second quarter of 2027. The project is based on extensive geotechnical investigations, which confirmed stable bedrock beneath the existing causeway, enabling engineers to develop a long-term solution that expands rather than completely rebuilds the existing crossing.

The new structure will be supported by deep piles driven into bedrock, while the historic convict-built causeway will be reinforced during the works. The crossing is designed with provision for an additional lane in the future, aiming to enhance the route's long-term capacity and resilience. Construction will involve drilling, grouting, and piling operations to establish the foundation for the new bridge structure.

The NSW Government has also announced an additional A$20 million assistance package to support businesses affected by the road closure. The funding will increase business grants to up to A$25,000 for the hardest-hit communities and extend financial assistance to eligible businesses in Lithgow, Oberon, and Blackheath.

NSW Roads Minister Jenny Aitchison said the project would provide a permanent solution for this critical transport corridor. "The NSW Government is not taking temporary patch-up measures," Aitchison said. "We are building a new crossing designed to serve the local community and freight for the next 100 years, because this community deserves a permanent solution, not a temporary fix." During construction, Transport for NSW will continue to upgrade detour routes and maintain additional public transport services.
