Changes on the way at intersection of Warringah Road and Forest Way

7 January 2019

Work on the Northern Beaches Hospital road upgrade at Frenchs Forest is moving ahead, with work progressing on the new underpass and road bridges.

A Roads and Maritime Services spokesperson said road users should prepare for a major change to how they travel through Frenchs Forest, as work continues on the important project to upgrade roads around the new hospital.

“Work is now being carried out on the 1.3 kilometre long underpass on Warringah Road which includes building three new road bridges at the intersections of Forest Way, Hilmer Street and Wakehurst Parkway,” the spokesperson said.

“To allow for the next stage of work on the new road bridge at Forest Way, the intersection will be reconfigured.

“The existing merge lane for motorists turning right out of Forest Way will be removed and a red traffic light and stop line will be introduced for motorists on Warringah Road travelling towards Chatswood.

“This means citybound motorists on Warringah Road will need to stop at a red traffic light while the motorists on Forest Way turn right onto Warringah Road.”

The spokesperson said this will be a significant change for motorists who are used to continuing through the intersection.

“Motorists are advised to drive carefully and be ready to stop on approach to the Forest Way intersection,” the spokesperson said.

“Heavy traffic and delays are expected in the area after the changes are implemented, especially in peak times.

“Motorists are advised to plan ahead, allow extra travel time and avoid driving in the morning and afternoon peaks where possible. Motorists can also download a real-time road app to find the best route using live traffic data.”

The spokesperson said these changes will be implemented between 7pm Saturday 12 and 8am Sunday 13 January, weather permitting.

“Work will be carried out to move barriers and traffic lights as well as carry out line marking,” the spokesperson said.

“NSW Police will be onsite to control traffic while the traffic lights are being turned on.

“Motorists are reminded to follow the direction of NSW Police, traffic control and all signs while work is being carried out.”

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

Work will continue to be carried out during standard construction hours, weather permitting.
