Sevenoaks is located at the junction of two ancient roads heading south from London and Dartford to the Weald. In 1710 part of one of the roads – from Sevenoaks through Tonbridge and Pembury to Tunbridge Wells – was the first in Kent to be turnpiked, and others followed within the century. It became the A21 road in the 1920s; the road now bypasses the town, and also takes traffic to the M25 London Orbital motorway at Junction 5. The Dartford road is now the A225. The cross-country A25 road passes through the north of the town along the Vale of Holmesdale.
