Northern Beaches Hospital Connectivity and Network Enhancement Project
The Northern Beaches Hospital Connectivity and Network Enhancement Project, to be completed in two stages, will improve traffic flow to the Northern Beaches through the Frenchs Forest area and will also facilitate access to the new Northern Beaches hospital, once constructed.
Stage 1 of the project, the Hospital Connectivity stage, comprises roadwork associated with intersection upgrades, widening and improvements to accommodate changed traffic conditions expected to be generated by the new Northern Beaches Hospital on Forest Way, Frenchs Forest Road and Wakehurst Parkway.
Stage 2, the Network Enhancement portion of the works, will encompass the main works associated with improving traffic movements along Warringah Road including a lowered four lane motorway section for through traffic between Wakehurst Parkway and Forest Way. Stage 2 also involves the replacement of an existing pedestrian bridge and the construction of two new pedestrian bridge servicing the High School and shopping centre, and three post tensioned overpass bridges at major intersections along Warringah Road.
