The A206 road links Greenwich with Greenhithe following the line of the River Thames. Today it is approximately 15 miles (24 km) in length, although the final section is a relatively new road. Its primary purpose is to link into the London Orbital motorway at the Dartford Crossing and is heavily used by lorries.
