Route

The southern end of the A23 at Brighton Pier
Main Article: A23/Route

The A23 is the London to Brighton road. Starting in Lambeth, it passes the various South London suburbs like Brixton, Streatham 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

The A23 at Handcross Hill in 1986
Main Article: A23/History

Unlike many of the First 99 that start in London, the A23's northern end has not really changed since Classification, although the section as far as Purley was originally numbered A22. The southern end has seen much more work. Today it is mostly D3 south of the M23 and an bypass of Crawley.

In 1956 to 1958 the A23 was rerouted around the east edge of Gatwick Airport which was being much expanded from the small prewar airport. Previously the A23 ran straight from Povey Cross to Lowfield Heath across where the airport is now.

Notable locations and improvements

Hooley Interchange

This is where the Northbound on-slip for the M23 would have been
Main Article: 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

The access point for the South Terminal at Gatwick Airport
Main Article: Gatwick Airport

Gatwick Airport has been a major destination for the A23 since 1935 with the original Beehive Terminal. It was upgraded in 1958 to become London's second airport. Today Gatwick is the world's busiest single runway Airport.


Handcross - Warninglid

Tree clearance - Handcross Hill

Main Article: A23/Handcross - Warninglid

From Spring 2012 to October 2014, this winding D2 section was improved to modern D3 standard, and the Slaugham junction was closed, with improved junctions at Handcross and minor changes at Warninglid. Plans in the 1990s included a fourth lane up the hill northbound, though three lanes each way was chosen. Preparatory works started in October 2011 with the works finishing in 2014.

Patcham interchange

The Patcham Interchange is the last GSJ of the A23. Built in the early 1990's for the A27 upgrade, it is a poorly designed junction built into a small valley.
