The Gore Hill Freeway is a 4-kilometre (2.5 mi) divided freeway located in Sydney, New South Wales, Australia. The freeway forms part of the M1, the Sydney Orbital Network, and the Highway 1 network. Construction of the freeway commenced in August 1988 as part of the Bicentennial Roads Program and opened to traffic on 26 August 1992. The primary function of the freeway is to provide an alternative high-grade route from Artarmon to Lane Cove and to reduce traffic demands on the Pacific Highway throughout Sydney's lower north shore, bypassing St Leonards and Gore Hill.
