Cumberland Highway is a 34-kilometre (21 mi) long urban highway located in Sydney, New South Wales, Australia. The highway links Pacific Highway and Pacific Motorway (M1) at Pearces Corner, Wahroonga in the northeast with Hume Highway at Liverpool in the southwest. 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: Pennant Hills Road, James Ruse Drive, Briens Road, Old Windsor Road, Hart Drive, Freame Street, Emert Street, Jersey Road, Betts Road, Warren Road, Smithfield Road, Palmerston Road, (New) Cambridge Street, Joseph Street and Orange Grove Road. The entire length of Cumberland Highway is designated part of route A28.

Pacific Highway is a 790-kilometre-long (491 mi) national highway and major transport route along the central east coast of Australia, with the majority of it being part of Australia's Highway 1. The highway and its adjoining Pacific Motorway between Brisbane and Brunswick Heads and Pacific Motorway between Sydney and Newcastle links the state capitals of Sydney in New South Wales with Brisbane in Queensland, approximately paralleling the Tasman Sea and the Coral Sea of the South Pacific Ocean coast, via regional cities and towns like Gosford, Newcastle, Taree, Port Macquarie, Kempsey, Coffs Harbour, Grafton, Ballina, Byron Bay, Tweed Heads and the Gold Coast, which is part of Queensland. Additionally, between Brunswick Heads and Port Macquarie, the road is also signed as Pacific Motorway, but has not been legally gazetted as such.
