Warringah Freeway is a 3.5-kilometre (2.2 mi) divided freeway in Sydney, New South Wales that is part of the Sydney Orbital Network. The primary function of the freeway is to provide an alternative high-grade route from the Sydney Harbour Tunnel and Bradfield Highway at Milsons Point to the A8 and Gore Hill Freeway. The freeway reduces traffic demands on Pacific Highway throughout Sydney's Lower North Shore, bypassing North Sydney and Crows Nest, and provides a vital link to access most of the suburbs in Sydney and is also a major route to the north, south, east and west of the central business district.

The A8 is a route designation of a major metropolitan arterial route through suburban north-eastern Sydney. This name covers a few consecutive roads and is widely known to most drivers, but the entire allocation is also known – and signposted – by the names of its constituent parts: Pittwater Road, Condamine Street, Burnt Bridge Creek Deviation, Manly Road, Spit Road and Military Road.
