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. The M2 motorway has replaced part of the A2 as the strategic route.

Dover is a town and major ferry port in Kent, South East England.

The town is the administrative centre of the Dover District and home of the Port of Dover.
