Gatwick Airport | roadworks


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

Tuesday 4 and Wednesday 5 June - full closure of westbound Gatwick Spur road (Junction 9 to 9A) 

The westbound Gatwick Spur Road will be closed overnight for two nights in order to complete the resurfacing works started during the recent 36 hour weekend closure.

Traffic management work will start from 20:00 and the spur road will be closed at 22:00. Both the southbound and northbound exit slips at Junction 9 will also be closed. The road will reopen to traffic at 04:00.

The main M23 carriageway and the eastbound spur road from the South Terminal roundabout to the motorway will remain open and unaffected by this work.

Tuesday 4 to Thursday 6 June - full closure of Crawley to Godstone M23 Link Road (M23 Junction 8) to M25 

Connect Plus will be closing the northbound M23 link road to the M25 anti-clockwise (Crawley to Godstone link) for three nights.

Northbound traffic will be diverted via the Crawley to Reigate link road and via the M25 clockwise to Junction 8 and return.

Saturday 8 June - full closure of the M23 in both directions

The M23 will be closed in both directions overnight on Saturday 8 June to facilitate installation of a new super-gantry. While the team aims to remove traffic management by 04:00, due to the size of the cranes involved, there is a possibility that works may overrun slightly.

The northbound carriageway will be closed between Junction 10 (Crawley) and Junction 8 (M25) from 21:00 to 05:00. Traffic for Gatwick will be diverted off the M23 at Junction 10 and via A2011 (Crawley Avenue), A23 (London Road) and Airport Way to reach the airport. Traffic for the M25 will be diverted off at Junction 10 and via the A264 and A22 to join the M25 at Junction 6 (Godstone).

The southbound carriageway will be closed between Junction 8 (M25) and Junction 9 (Gatwick) from 22:00 to 05:00. The M23 southbound will remain open from Junction 9 to Junction 10. Southbound traffic will be diverted via Junction 6 of the M25 (Godstone), A22 and A264 to join the M23 at Junction 10. Traffic for Gatwick will then follow the local diversion via Crawley to reach the airport.

Sunday 9 June - full M23 southbound closure from Junction 8 to Junction 9

The southbound carriageway will be closed overnight between Junction 8 (M25) and Junction 9 (Gatwick) to facilitate installation of a new cantilever gantry.

Traffic will be diverted via the M25 Junction 6 (Godstone), A22 and A264 to join the M23 at Junction 10 (Crawley).

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.
