Roadworks information - M23 resurfacing April 2018
8th April 2018

What's happening?

Highways England, A-one+ will be carrying out some resurfacing work Northbound on the M23 between junctions 10 (Copthorne) and 9 (Gatwick). This is to complete the previous works that were postponed by severe weather conditions in January 2018.


Traffic management

In order to carry out these works as efficiently and as safely as possible, we will be implementing a slip road closure and lane closures on the M23 in addition to using a full road closure of the London bound carriageway on the M23, between 10pm on Friday evening to 4am on Monday morning on the dates listed below. The Southbound carriageway is unaffected.


Unfortunately, weekend closures are unavoidable due to the nature and scale of the work involved.

Please be aware that these works have been carefully programmed but are subject to change due to weather conditions and unforeseen circumstances. The dates of the 26, 27, 28 and 29 April are being held as contingency in case of inclement weather.


Diversion routes

Clearly signed diversion routes will be in place during all closures and we will be using local routes which are suitable for all types of vehicles.

We are working closely with partner organisations to minimise disruption for residents during our works but an increase in traffic along the diversion routes is unfortunately unavoidable.


How do I get to Gatwick airport?

Northbound traffic for Gatwick airport will exit the M23 at junction 10 and take the A2011 Crawley Avenue to the A23 London Road to reach Airport Way and the North Terminal roundabout to the South Terminal.


How do I get to the M25?

Northbound traffic for the M25 will exit at junction 10 and follow the A264 through Copthorne, turning left (northbound) onto the A22 at the traffic lights at Felbridge.

Traffic will continue northbound on the A22 through New Chapel, Blindley Heath and South Godstone, reaching the M25 at the junction 6 Godstone interchange.


Are you working on the M23 Southbound?

The M23 Southbound carriageway will not be closed during these works and all Gatwick airport traffic will be able to exit at junction 9 or continue Southbound towards Brighton as usual.
