A minor three-car prang on the A27 Brighton bypass has caused a three-mile Rush-hour tailback from the A23 turn-off at Patcham.
The Highways Agency warned of slow traffic and the road being partially blocked due to the accident on eastbound side of the A27.
It happened just after 7.15am between the A2038 Hove turn-off – King George VI Avenue, also known as Snakey Hill, and Mill Road, Dyke Road Avenue and Devil’s Dyke Road – and the A23 London Road at Patcham.
Sussex Police said that no one appeared to have been injured in the crash which was on the slip road to the A23.
