The M80 Ring Road (also known as simply the Ring Road or by the name of its constituent parts: Western Ring Road and Metropolitan Ring Road) is a currently incomplete urban freeway ring road around Melbourne, Australia. This article will deal with the entire length of the corridor for sake of completion, as well to avoid confusion between declarations. The ring road connects Melbourne's western suburbs and northern suburbs to other Victorian urban and rural freeways (the West Gate and Princes Freeways, Western Freeway, Calder Freeway, Tullamarine Freeway and Hume Freeway), and also relieves freight traffic from Sydney Road, Pascoe Vale Road and Geelong Road. With connections to every major interstate and regional freeways, it has encouraged both industrial and residential growth in Melbourne's western suburbs. A series of major upgrades along the entire route commenced in 2009, including widening and a Freeway Management System; the most recent section between Sydney and Edgars Roads commenced construction in 2020 and was completed in 2022, one year ahead of schedule.
