Route

This is the A3 at Hindhead

Main Article: A3 route

A road with some history and strategic significance, as it connects London with its principal naval port. In the times of the Napoleonic Wars, when the Straits of Dover were vulnerable, this road became London's principal link with the Channel ports. Its history has also given it more than its fair share of reputations for highwaymen.

History

The A3 at Hook during the 1960's

Main Article: A3 history

The A3 like many roads was mainly S2 at Classification. Since then most of the road has been upgraded to Dual Carriageway, the section at Hindhead being the last truck section of single carriageway outside TfL control.
