A23 Road

The A23 road is a major road in the United Kingdom between London and Brighton, East Sussex, England. It became an arterial route following the construction of Westminster Bridge in 1750 and the consequent improvement of roads leading to the bridge south of the river by the Turnpike Trusts. The increase in population of Brighton in the late eighteenth century, which transformed it from a small fishing village to a large seaside resort, enhanced the importance of this road, as did the residence there of George IV, as Prince of Wales, who made Brighton a place of fashion. The original A23 has been bypassed around Croydon, and by the M23 motorway for the section between Hooley and Crawley.

The 53-mile (85 km) route from London to Brighton forms the basis of the route of the annual London to Brighton Veteran Car Run. This is featured in the film Genevieve, although most of the rural motoring scenes were shot in Buckinghamshire. The A23 is used for various other London to Brighton events.
