THE M4 has now reopened following a recovery operation to remove an overturned lorry.
Motorists had been advised to allow extra time for their journeys after the HGV overturned between Swindon and Chippenham this morning.
A diversion was put in place while the westbound carriageway was closed between junctions 16 and 17 to allow the HGV to be recovered.
Lane one had been closed since earlier this morning following the incident when the HGV left the carriageway, hit the nearside barrier and overturned.
Highways England Asset Delivery Manager Kevin Hamer said: “The full westbound closure was put in place between junctions 16 and 17 to reduce the impact on peak Friday traffic.
“To have just two lanes running through the Friday peak time and into the evening would have led to longer disruptions for road users. The full closure, with diversion routes, kept disruption to a minimum and we thank customers for their patience during the incident and the recovery of the vehicle.”
