The A2 is a major road in south-east England, connecting London with the English Channel port of Dover in Kent. This route has always been of importance as a connection between London and sea trade routes to Continental Europe. It was originally known as the Dover Road.^[1] The M2 motorway has replaced part of the A2 as the strategic route.

Unlike the other single digit A-roads in Great Britain, the A2 does not form a zone boundary. The boundary between Zones 1 and 2 is the River Thames.
