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.

The M8 Motorway is a 15.2-kilometre (9.4 mi) tolled dual carriageway motorway in Sydney that is designated the M8 route marker. It consists predominantly of tunnels and includes tunnel connections to the future Western Harbour Tunnel and the M6 Motorway.
