A single vehicle crash closed the M23 near Pease Pottage in Crawley on Friday morning.
The motorway was closed in both directions near junction 11 after a Smart car travelling north, left the road and collided with the central barrier at around 8.15 am. After being initially alerted to attend, the Kent, Surrey and Sussex Air Ambulance was stood down.
The southbound carriageway and two lanes northbound were re-opened at around 9 o’clock in order to disperse a heavy build up of traffic.
