Traffic is said to be coping well.

 

National Highways said the closure is expected to be in place for several hours for police investigation work.

Wiltshire Police are currently at the scene and are urging motorists to find alternative routes.

They said on Twitter: "RPU are currently at a collision on the Northbound A419 exit slip road to Commonhead/Marlborough Road, Swindon.

"It is anticipated that the road will remain closed for some hours. Please find an alternate route."

A witness driving past the scene said: "The road is currently blocked off with cones as you come off the M4 and is police taped at the Commonhead roundabout end. 

"There is a coach a few metres down from the police tape and at least one car."

The coach was described as not having any obvious signs of damage.

The road reopened just before 8pm.
