The night closures affecting the M23 from tonight

The night closures affecting the M23 from tonight

Published by the Eagle Radio News Team at 6:00am 12th May 2019. (Updated at 1:10pm 16th May 2019)

There are a number of night time closures up and down the M23 this week as work takes place to upgrade it to a Smart Motorway.

The £164 million project between junctions 8 and 10 began back in 2016 and is scheduled to be completed by Spring 2020.

Highways England says it is necessary as the M23 connects Crawley and Gatwick Airport to the M25, routes into London and the rest of the UK. 

The scheme aims to:

  • Reduce congestion by smoothing the flow of traffic to improve journey times and make them more reliable
  • Facilitate economic growth within the region, by providing much-needed capacity on the motorway
  • Maximise motorway capacity while maintaining safety

May 16: 9pm-4am

  • There will be a full closure from junction 10 to junction 8 northbound plus the Gatwick Spur entry slip will be closed.
  • A diversion route will be via junction 10 of the M23, A264, A22, rejoining at junction 6 of the M25.
  • The Diversion for Gatwick will be at Junction 10 M23, A2011, A23, Airport Way and into Gatwick Airport.

May 17-19: (10pm Friday - Midday Sunday, 36 hour closure)

  • Junction 9, the Gatwick Spur road and roundabout will all be affected by this. 
  • The southbound exit slip and northbound exit slip will be closed for traffic.
  • There will be NO access into Gatwick Airport from junction 9.
  • The M23 main carriageway in both directions will be open for traffic.
  • There will be a fully signed diversion route in place, which will be from junction 10 of the M23 to Gatwick Airport– via the A2011, A23, Airport Way leading to the North and South Terminals. To the M25 – via Junction 10 of the M23, A264, A22 follow signs to Godstone and join M25 at Junction 6.
