The Gore Hill Freeway is a 4-kilometre (2.5 mi) divided freeway located in Sydney, New South Wales that is part of the Sydney Orbital Network and the Highway 1. 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.
