New bridge takes shape along Warringah Road at Frenchs Forest

20 December 2018

Work is in full swing at the intersection of Warringah Road and Hilmer Street at Frenchs Forest, with a new road bridge now being built as part of the Northern Beaches Hospital road upgrade project.

 A Roads and Maritime Services spokesperson said this work is being delivered as part of the 1.3 kilometre long underpass on Warringah Road which will provide more capacity for motorists once complete.

“Crews were out in force last weekend to continuously pour around 500 cubic metres of concrete across eight hours to get the new bridge deck just right,” the spokesperson said.

“As part of the project, three road bridges are being built along Warringah Road at the intersections of Forest Way, Hilmer Street and Wakehurst Parkway, and will cross over the new underpass.

“Around 70 truckloads of concrete was transported to site from a concrete batching plant, placing concrete simultaneously using two concrete pumps.

“The work carried out during the weekend was a great visual of what it takes to form new roads on existing infrastructure.”

The spokesperson said once all three bridges and the underpass are completed, motorists will enjoy smoother trips along Warringah Road.

“Thousands of vehicles use Warringah Road each day but this number is expected to increase as the Northern Beaches community grows,” the spokesperson said.

“A lot of planning has gone into this exciting milestone, with dozens of engineers planning for around 20 workers to carry out the continuous concrete pour.

“Now the Hilmer Street bridge deck has been poured, Roads and Maritime Services will install bridge barriers and screens, lay asphalt as well as install new traffic signals and line marking in the coming months.”

The spokesperson said when the upgrade along Warringah Road is complete, motorists will enjoy a better travel experience and increase road capacity around the hospital precinct.

“Motorists are already enjoying improved access to key intersections along Frenchs Forest and Naree roads including Wakehurst Parkway, Rabbett Street and the entrance to the new hospital, but crews are continuing to work hard on the second stage of the upgrade,” the spokesperson said.

“In the coming months, the community will see work ramping up on the underpass, which will be carried out in stages to minimise the impact to motorists.

“Building the underpass will be a complex task but once complete, it will provide motorists with improved traffic flow and safety for years to come.

“The community and motorists are thanked for their continued patience and will continue to be kept updated.”
