M80 Ring Road

The M80 Ring Road (also known simply as the Ring Road or by the names of its constituent parts; the Western Ring Road and the Metropolitan Ring Road) is a partially complete urban freewayring road around Melbourne, Australia.

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 freeway, 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.

The North East Link is currently under construction between the Greensborough Bypass, the north-eastern end of the Ring Road, and the Eastern Freeway. Expected to open in 2028, this will create a freeway-standard ring road encircling Melbourne, from Laverton North in the western suburbs to Frankston in the south-eastern suburbs.
