MAR 2020Opening Warringah Road underpass to traffic

The opening of the underpass will occur over two weekends, weather permitting:

  • Saturday 28 March 2020 - open Warringah Road underpass eastbound and westbound lanes
  • Saturday 4 April 2020 - open Warringah Road underpass on ramp at Wakehurst Parkway

Warringah Road underpass

A number of construction activities can only take place after the underpass is open to traffic. This will take a few months to complete and we are on track to complete the project in mid‑2020, weather permitting.

When fully operational the 1.3 kilometre long underpass will enable through traffic on Warringah Road to bypass three sets of traffic lights at Forest Way, Hilmer Street and Wakehurst Parkway.

Saturday 28 March

From Saturday night 28 March, the underpass will open to eastbound traffic at the entrance near Fitzpatrick Avenue.

From Sunday morning 29 March, the underpass will open to westbound traffic at the entrance west of Allambie Road.

At this time:

  • the Warringah Road underpass on ramp at Wakehurst Parkway will be closed
  • Warringah Road westbound surface lanes on approach to Wakehurst Parkway will be reduced to two lanes
  • Warringah Road eastbound surface lanes on approach to Forest Way will be reduced to two lanes
  • motorists using the Forest Way slip lane to Warringah Road eastbound will enter Warringah Road in an added lane - no merge will be required at that point.
