The first phase of the $2.2 billion Coffs Harbour Bypass project is complete, with the project on track to open to traffic in late 2026.
The Coffs Harbour bypass tunnelling team working on either side of the 410-metre-long Gatelys Road Tunnel broke through the northbound tube on last week.
This week, they have broken through the southbound tube, completing the first major phase of the three tunnels to be built as part of the bypass.
A breakthrough at the 320-metre-long Shephards Lane tunnel is expected in mid-April next year.
Each of the three tunnels will have two tubes, with each tube capable of carrying two lanes of traffic, along with room to accommodate cyclists.
Workers will now start excavating the tunnel floor, carry out the permanent tunnel lining works, install drainage, build the pavement, and complete the fit-out of the mechanical, electrical, fire, safety and intelligent transport systems.
All the equipment will then be tested and commissioned before the bypass is opened to the public.
“During consultation ahead of the project in 2016, the people of Coffs Harbour were very clear they wanted tunnels instead of cuttings and it is great to see progress in bringing that to fruition,” said Federal Infrastructure, Transport, Regional Development and Local Government Minister Catherine King.
“Being able to pass through from one side of this large hill to the other is a major achievement, and I look forward to the work over the next two years as the tunnels start to take their final shape.”
Once complete, the project is expected to remove 12,000 vehicles from the CBD, along with reducing travel times.
The Australian Government is investing $1.76 billion towards the project, with the remaining $440 million provided by the New South Wales Government.
