EMERGENCY crews are attending a crash on the A303 just prior to the Countess Roundabout on the westbound carriageway.
It is believed one person might be trapped and firefighters are there. No serious injuries are reported.
Four vehicles are involved in the collision: a blue BMW, a silver Vauxhall, a white Mercedes and a black Scania.
A black fiesta is also in the area because it has broken down.
The road is closed with recovery being arranged and police then hope to open one lane.
Police are urging drivers to find alternative routes.
