The Western Ring Route is a motorway system being constructed in Auckland, New Zealand. It runs along three existing state highways: the Southwestern Motorway (SH20), the Northwestern Motorway (part of SH16) and the Upper Harbour Highway (SH18). When finished it will surpass the Southern Motorway to become the longest motorway in New Zealand at 48 kilometers in length. It will run through Manukau, Waitakere, and the North Shore, bypassing the Auckland city centre and thus providing a second motorway route through the Auckland isthmus.
