Motorists are being told to avoid the stretch of West Sussex road where a display fighter jet was involved in a fatal crash at the weekend.
At least 11 people tragically died after a Hawker Hunter plummeted into the busy Shoreham stretch of the A27 at around 1.20pm on Saturday - and the figure could still rise.
Drivers are being warned that the road could stay shut for a few more days.
The A27 has been badly damaged and littered with debris. The wreckage of the jet will not be fully removed until Monday.
It remains shut from the Shoreham-by-Sea stretch of the A293 and the Lancing stretch of the A2025. Highways England officials are advising drivers who cannot avoid the area to allow more time before they leave.
An agency spokeswoman says that westbound motorists should leave the A27 road before its A283 junction closure.
They should then head towards Washington on the northbound A283, take the southbound A24 and then rejoin the A27, ensuring that they follow the black triangle sign, she said.
Eastbound motorists should leave the A27 road before its closure at its A24 junction.
They should then head in the direction of Washington, take the A283 before rejoining the A27, ensuring that they follow the black diamond sign.
Air accident officials and safety experts spent Sunday looking for evidence as well as taking away bodies. They are investigating how the Shoreham Air Show exhibit burst into a devastating fireball.
