Work has begun installing 70 massive super-T girders on twin bridges, part of the Coffs Harbour Bypass project in NSW.
At 250 metres long and around 16.5 metres high, the bridges are the longest and the highest for the 14 km long project.
The piles, columns and headstocks are complete on the twin bridges that will span NSW’s north coast railway line.
More than half of the project’s 21 bridges on the bypass project are now complete, marking significant progress on the $2.2 billion infrastructure project whose construction commenced in 2023.
By the end of this year, only three bridges will remain under construction, with the final asphalt surfacing to be laid across all road bridges before the Coffs Harbour Bypass opens to traffic in late 2026.
Arcadis is the lead designer for the Ferrovial Gamuda Joint Venture (FGJV) comprising Ferrovial Construction (Australia) and Gamuda Australia that was awarded the $1.35 billion major works contract for client, TfNSW.
NSW Minister for Roads, Jenny Aitchison, said the project isn’t just about faster travel times.
“It’s also about protecting local waterways, flora and fauna, and maintaining local access for motorists and pedestrians.”
Ms Aitchison added that the completed bypass along with the M1 to Raymond Terrace extension, people traveling from Sydney to Brisbane will not pass a single set of traffic lights. She called this a ‘gamechanger for regional connectivity, freight operations and road safety’.
The entire project is expected to be complete by late 2027.
