Warringah Freeway Upgrade is a critical component to the Western Harbour Tunnel and Beaches Link (WHTBL) Program. The Incentivised Target Cost style contract has a total value of $1.18 billion. It will enable the connection of the new WHTBL motorways into the existing motorway network, ensuring the WHTBL Program delivers its connectivity and safety benefits for public transport, freight, and private vehicle customers, while improving the journey experience for existing Warringah Freeway users.
The project is designed to boost transport capacity around the Harbour CBD and improve connectivity to and from the Northern Beaches. Once complete, the upgraded corridor will optimise traffic flow across Sydney Harbour Tunnel, Sydney Harbour Bridge and Western Harbour Tunnel.
The Warringah Freeway Upgrade consists of surface road upgrades, structural and bridge works, and ancillary works of an approximate four-kilometre section of the freeway corridor. The upgrade is focused on the simplification of traffic flows and wayfinding, as well as enabling works for the new WHTBL and Northern Beaches Link.
