Long traffic queues have built up to and from Brighton and Hove as accident investigators continue their work on the A27 where an aircraft crashed the weekend.
The road is closed from Shoreham to Lancing with diversions in place. Journey times are much longer than usual. Sussex Police urged people to steer clear of the area.
The Hawker Hunter jet crashed during the Shoreham airshow on Saturday (22 August), coming down on the A27 by the Sussex Pad traffic lights.
Although the pilot Andy Hill was pulled alive from the wreckage, at least 11 people and possibly as many as 20 are feared to have died.
Mr Hill was taken to the Royal Sussex County Hospital in Brighton. He was described as being in a critical condition.
The organisers of the Shoreham airshow said: “Following the tragic incident at Shoreham airshow on Saturday, the Royal Air Forces Association, the event organisers and Brighton City Airport are continuing to work closely with the emergency services.
“Our thoughts are with those who have been killed or injured, their families and friends and all those who have been affected by the events.
“We would also like to pay tribute to the emergency services for their work at this distressing time.
“Sussex Police and the Air Accidents Investigation Branch have asked that anyone with photographs or video footage that may help with their investigations should send their contact details to shoreham.aircrash2015@sussex.pnn.police.uk.
“Do not send files, just contact details and information about the material you have.
“All vehicles, irrespective of size are now able to leave the airport. Motorists are being asked to avoid the A27 in the Shoreham area while investigations into the crash continues.”
