North Sydney to Northern Beaches capacity improvements
Residents of the Northern Beaches rely heavily on private vehicles and public buses for travel. Public transport travel times can be long and unreliable.
The 2019 Australian Infrastructure Audit ranks the North Sydney–Northern Beaches Corridor as the fourth most congested corridor in Sydney’s evening peak periods during 2016, and forecast seventh most congested in 2031, as measured by total vehicle delays.
Sydney’s population of is forecast to grow from five million to eight million people over the next forty years. Travel demand across Sydney Harbour and onto the Northern Beaches is projected to increase, further exacerbating the already high levels of congestion.
Potential options for addressing the identified problems focus on a motorway connection from the Warringah Freeway and the Gore Hill Freeway at Artarmon to Balgowlah and Killarney Heights, and an upgrade of the Wakehurst Parkway.
The proposal includes an access road connection at Balgowlah and complementary intersection modifications.
This proposal is expected to benefit freight, public transport and private vehicle users.
Together with the Western Harbour Tunnel and Warringah Freeway Upgrade Investment read proposal (Stage 3), this proposal captures the previous Western Harbour Tunnel and Beaches Link Priority Initiative on the Infrastructure Priority List.
The Northern Beaches (A8) corridor capacity Early-stage proposal (Stage 1) is separately included on the Infrastructure Priority List to address the part of the congestion problem in the Northern Beaches from Seaforth to Mona Vale.
