One driver has been taken to hospital after two HGV lorries collided on the M4 earlier on Saturday morning.
Police and ambulance crews were called to the westbound route of the M4 near Swindon at 3.30am on April 2 between junction 15 A346 Marlborough Road and junction 16 A3102 Swindon Road. The incident caused 50m of damage to an extensive section of the central reservation barrier, according to National Highways.
Both eastbound and westbound carriageways were initially closed after the collision. Westbound remains completely closed between junctions 15 and 16 to allow for police investigations with only one lane open on the eastbound carriageway.
