M4 reopens after tanker crash in Newport's Brynglas tunnels
A section of the M4 closed following a tanker crash in the Brynglas tunnels in Newport has been reopened.
The westbound carriageway was closed for almost four hours while the vehicles were recovered.
Motorists also reported delays of up to an hour on the A449 on the approach to the Coldra roundabout at junction 24, while congestion was said to be heavy on the A48 Southern Distributor Road.
The incident happened as the vehicles travelled towards Cardiff at 06:30 GMT.
One tanker was said to be carrying sand and there was no hazardous material involved.
A major deployment of fire and rescue crews was launched as a precaution but there were no reports of a blaze or serious injuries.
Firefighters from Maindee, Malpas, Dyffryn, Cwmbran, New Inn and Whitchurch were sent to the scene, as well as a number of specialist vehicles.
