An 11-kilometre tunnel between Katoomba and Lithgow has been proposed, with investigations into what would be Australia’s longest connected tunnel beginning.
Deputy Premier John Barilaro said the Greater Western Highway upgrades would better connect the states Central West to the East Coast.
“This is an immensely complex and ambitious plan, but we’re working hard to make it happen because we know what a difference it will make to the lives of commuters,” Barilaro said.
“This corridor will enhance the state, significantly cutting travel times between the city and the bush,” he said.
Minister for Regional Transport and Roads Paul Toole said the proposal would link two planned tunnels at Blackheath and Mount Victoria.
“This would be a history-making project, delivering Australia’s longest road tunnel and allow motorists to avoid all the current pinch points from Blackheath,” Toole said.
“It will also mean less disruption for residents and businesses during construction and a smoother, safer journey.”
Construction on the highway upgrade is expected to start in 2022, with the full upgrade set to be completed by 2032.
