Warringah Road underpass reaches new milestone

5 December 2019

Excavation of the new Warringah Road underpass will be completed by the end of this year, with the key link near the Northern Beaches Hospital reaching the road level.

Transport for NSW Senior Project Manager Scott Little said once complete, the new 1.3 kilometre long underpass will provide more capacity for the thousands of motorists who use Warringah Road each day.

"The underpass is a key part of the Northern Beaches Hospital road upgrade which will improve traffic flow and safety for motorists for years to come," Mr Little said.

"Since work started on the underpass in October last year, more than 130,000 cubic metres of soil, rock and other material has been removed, with excavation now 95 per cent complete.

"While the remainder of the material is removed from the underpass, crews will continue to form the support walls and the new roadway."

Mr Little said the large amount of spoil excavated from the underpass is continuing to be reused at the former Belrose landfill.

"Once all excavation is completed by the end of this year, work will ramp up at both ends of the underpass," Mr Little said.

"Work will involve rebuilding the road at the entry and exit points of the underpass, with excavation reaching up to one metre deep in places."

Mr Little said changed traffic conditions will be in place from early January while work is carried out.

"Temporary lane closures will be in place along Warringah Road during the January school holidays while traffic volumes are lower," Mr Little said.

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