The M60 motorway, Manchester Ring Motorway or Manchester Outer Ring Road is an orbital motorway in North West England. Built over a 40-year period, it passes through most of Greater Manchester's metropolitan boroughs except for Wigan and Bolton. Most of Manchester is encompassed within the motorway, except for the southernmost part of the city (Wythenshawe and Manchester Airport) which is served by the M56. The M60 is 36.1 miles (58.1 km) long and was renamed the M60 in 1998, with parts of the M62, M66 and all of the M63 being amalgamated into the new route, and the circle completed in 2000. The road forms part of the unsigned Euroroutes E20 and E22 from junctions 12 to 18. In 2008, the M60 was proposed as a cordon for congestion charging in Greater Manchester, although this was rejected in a referendum relating to the Greater Manchester Transport Innovation Fund.
