The M20 is a motorway in Kent, England. It follows on from the A20 at Swanley, meeting the M25, and continuing on to Folkestone, providing a link to the Channel Tunnel and the ports at Dover. It is 50.6 miles (81.4 km) long. Although not signposted in England, this road is part of the European route E15. It is also used as a holding area for goods traffic when traffic across the English Channel is disrupted, such as Operation Stack and Operation Brock.
