ONE lane of the M4 westbound between Junction 16 and 17 was closed earlier this afternoon following a two car crash. 

Wiltshire Police were forced to close the outside lane between Chippenham and Swindon at approximately 2pm today (Saturday) due to the collision. 

The vehicles were removed from the road at 3.20pm but Highways England estimate there are at least three mile tailbacks. 

More to follow.
