The Warringah Freeway Upgrade includes the construction and modification of twelve structures, including bridges, ramps and underpasses, some of which were built over 50 years ago. These structures are being built or modified as part of the Warringah Freeway Upgrade, connecting communities across the freeway from east to west and streamlining traffic movement onto the freeway northbound and southbound. This dedicated page will be updated regularly so motorists are notified of upcoming permeant traffic changes.
