Roadworks

There are planned roadworks and/or closures that may impact your journey to or from the airport.

 

Monday 16 to Wednesday 18 and Friday 20 September - Full Northbound M23 Closure Junction 10 to 8 

The M23 will be closed Northbound for four nights next week (Monday-Wednesday and Friday) between Junction 10 (Crawley and Junction 8 (M25). There is no work on Thursday night due to Network Rail engineering works on the diversion route.

Traffic for Gatwick will be diverted off the M23 at Junction 10 and follow the local diversion route to the airport (A2011, A23 and Airport Way).

Northbound traffic for the M25 will be diverted off the M23 at Junction 10 and follow the A264 and A22 to join the M25 at Junction 6 (Godstone).

Monday 16 to Sunday 22 September - Closure of Junction 10 southbound exit slip road

Lane 1 and 2 of M23 southbound will be closed between Junction 9 and Junction 10, leading to a full closure of the Junction 10 (Crawley) southbound exit slip road.

Traffic wishing to exit the M23 at Junction 10 will be diverted to Junction 10a and return via the northbound carriageway.

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.
