The M23 is a motorway in the United Kingdom, running from the south of Hooley in Surrey, where it splits from the A23, to Pease Pottage, south of Crawley in West Sussex where it rejoins the A23. The northern end of the motorway starts on what is effectively a 2-mile (3.2 km) spur north of junction 7 of the M25 motorway (junction 8 on the M23). From Hooley it runs for 17 miles (27 km) past Redhill, Gatwick Airport and Crawley. A spur runs from junction 9 to Gatwick Airport.
