From Stane Street to the A3
Clapham Road is now part of the A3 Portsmouth Road, entering Lambeth where Kennington Park Road becomes Clapham Road and Clapham High Street. It carries significant commuter traffic between the City of London and the south coast, threading through Clapham, Stockwell and Kennington as a congested urban artery.
Yet the road itself predates the modern motor age by nearly two millennia. No trace of the Roman surface has been found in Lambeth, but there can be little doubt that it ran along Kennington Park Road and Clapham Road. The former was part of Stane Street, which ran from the East Gate of Chichester through Pulborough, Dorking and Tooting to London. What began as a military highway has evolved, over centuries, into one of London’s busiest approach roads.
