There are planned roadworks and/or closures that may impact your journey to or from the airport.
Saturday 27 and Sunday 28 - Full closure of M23 Junction 10a southbound off ramp
Resurfacing works at Junction 10a to improve safety will close the southbound off-slip for 2 nights on Saturday 27 and Sunday 28 July. Work will take place between 20:00 and 06:00. This work is not expected to cause any impact to Gatwick journeys.
Traffic wishing to exit the M23 southbound at Junction 10a will be diverted onto Junction 11 (Pease Pottage). At the roundabout take the A23, Brighton Road. At the first roundabout take the third exit onto Southgate Avenue to Crawley Town Centre. Turn Right into Haslett Avenue East (A2220). Follow the A2220 and at first roundabout take the third exit onto the B2036, Balcombe Road. Balcombe Road will take traffic back to the M23 Junction 10a.
M23 Smart Motorway project
Highways England are upgrading the M23 between Junction 8 (M25) and Junction 10 (Crawley) to an all lane running (ALR) smart motorway. Construction starts in June 2018 and will run to spring 2020.
When it’s finished, the M23 will have four running lanes in each direction with a variable speed limit controlled by dynamic signage. The westbound spur road (towards Gatwick) will also be upgraded to three running lanes.
How will this impact journey times?
Journey times will be longer than normal. Although the usual three lanes will be maintained throughout the two-year project, a reduced speed limit of 50mph will be in place due to narrow lanes.
Why is the M23 being upgraded?
The M23 is a very busy road used by traffic travelling to and from the airport and between Brighton and London, particularly during holiday periods. As a result, safety, congestion and journey times need to be improved, which can be facilitated by a smart motorway.
