Route
The A23 is the number of the London to Brighton road. Starting at Westminster Bridge, it passes the various South London suburbs like Brixton, Stratham and Croydon before becoming non-primary at Hooley. It then goes though Redhill, passes Gatwick Airport and Crawley before resuming Trunk status at Pease Pottage Interchange before the run to Brighton where it ends on the Seafront on a roundabout with the A259. Part of the road is also in the South Downs National Park.
History
Unlike many of the First 99 that start in London, the A23's northern end hasn't really changed since Classification. The southern end on the other hand has seen much more work. Today mostly D3 south of the M23 and an bypass of Crawley.
Future
Handcross - Warninglid
Main Article: A23/Handcross - Warninglid
Plans to widen the poor quality D2 section to modern D3, with improvements to the junctions at Handcross, Slaugham and Warninglid. Plans in the 1990s included a fourth lane up the hill northbound, though this is not in the current plan. Preparatory works started in October 2011. Main works currently expected to start in spring 2012 and last for two and a quarter years.
Notable locations and improvements
Hooley Interchange
The Hooley Interchange is where the A23 finally loses trunk status to the M23. Due to the failure of the Ringway Project, today the M23 ends here instead of further north.
Gatwick Airport
Gatwick Airport has been a major destination for the A23 since 1935 with the original Beehive Terminal. Upgraded in 1958 to become London's second airport, today Gatwick is the world's busiest single runway Airport.
Patcham Interchange
The Patcham Interchange is the last GSJ of the A23. Bulit in the early 1990's for the A27 upgrade, it is a poorly designed junction built into a small valley.
