The M23 is short but dense: it carries almost all of Gatwick Airport's road traffic between the M25 at Merstham and Crawley. The smart-motorway section around J9 for the airport is the focal point, and problems on the M25 south-west quadrant back up onto it quickly. Live incidents and closures refresh every 5 minutes.
