Western Ring Route

The Western Ring Route is a motorway system in Auckland, New Zealand. It runs along the entire Southwestern Motorway, most of the Northwestern Motorway, the entire Upper Harbour Motorway, and the entire Upper Harbour Highway. When the Upper Harbour Highway is upgraded to motorway status, the route will surpass the Southern Motorway to become the longest motorway in New Zealand at 48 kilometres in length. It runs through Manukau, West Auckland, and the North Shore, bypassing the Auckland city centre and thus providing a second motorway route through the Auckland isthmus.
