A section of the M23 has been closed for hours after a fatal crash near Gatwick Airport.
The crash, involving one vehicle, happened on the M23 southbound at J9 for Crawley and Gatwick at about 1am.
Drivers face severe delays as the motorway is expected to remain shut into the afternoon while a crash investigation is carried out.
People travelling to the UK’s second busiest airport are told to allow extra time and to use alternative routes.
National Highways said: ‘Due to the serious nature of the incident, Sussex Police investigations remain ongoing and will continue to take place throughout the day. The carriageway is expected to remain closed until at least early afternoon.
‘Road users heading to London Gatwick Airport this morning are advised to allow plenty of extra time and to consider alternative routes.’
Delays are building up in the area in both directions, with rush hour traffic snarling back to junction 10.
Sussex Police said: ‘The southbound carriageway there is likely to be closed all morning following the collision, which happened just before 1am.
‘Diversions are in place and motorists are encouraged to plan alternative routes.’
The force asked any eyewitnesses or motorists with dashcam footage to get in touch.
A stretch of the M23 is also closed at junction 8 for the M25, but it is not known whether this is related to the same incident.
