The M56 motorway serves the Cheshire and Greater Manchester areas of England. It runs east to west from junction 4 of the M60 at Gatley, south of Manchester, to Dunkirk, approximately four miles north of Chester. With a length of 33.3 miles (53.6 km), it connects North Wales and the Wirral peninsula with much of the rest of North West England, serves business and commuter traffic heading towards Manchester, particularly that from the wider Cheshire area, and provides the main road access to Manchester Airport from the national motorway network.

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 which is served by the M56.
