Three people were reported to have suffered 'significant' injuries after a bus carrying workers to the Hinkley Point C construction site overturned on Tuesday morning.

The incident happened at around 6am in icy conditions near Cannington and is believed to have involved a motorcycle.

The A39 Quantock Road was closed both ways between B3339 Sandford Hill near Cannington to Quantock Meadow at Bridgwater.

EDF said transport to and from the construction site of the new nuclear power station was suspended following the crash.

Of the 70 workers travelling on the bus, there are understood to be 3 significant injuries sustained.

In a statement, Ian Liddell-Grainger, MP for Bridgwater and West Somerset said the crash happened as the bus was doing down Sandford Hill, west of Bridgwater.

He said: “Obviously it was a terrifying experience for everyone on that bus and my thoughts are with them and their families.

“But we absolutely most get to the bottom of why this crash occurred because EDF is very conscious of the need to maintain the highest safety standards for the protection of their workers - and that concern naturally extends to those periods when they are being transferred to and from the site.

“I am aware police have been reporting a high number of accidents in the area this morning, all of them blamed on icy road conditions. We need to establish as soon as we can whether similar circumstances played a role in this particular event.”

In a statement a spokesperson for Hinkley Point said: “A bus carrying members of the Hinkley Point C workforce has been involved in a traffic incident on the A39 in Bridgwater. Emergency services are on the scene and travel to and from the site has been suspended."

The Dorset and Somerset air ambulance attended the incident, and another was also reported to have landed nearby.

Avon and Somerset Police said in an early morning statement: “The A39 Quantock Road, in Bridgwater, has been closed due to an overturned double-decker bus. Officers were called at around 6am today (Tuesday 17 January) following the road-related incident. Emergency services are at the scene.”

Devon and Somerset Fire and Rescue Service confirmed it was at the crash. In a statement released on Twitter they confirmed that: “Fire crews are working alongside our emergency services colleagues on this incident.”

The crash happened as roads across the area were affected by icy conditions. A Yellow Weather Warning for ice had been issued by the Met Office for Ice across much of the South of England.

Avon and Somerset Police reported there had been more than 100 road incidents overnight.

The force said: “We are advising the public to only travel if essential after the police received more than 100 reports of road-related incidents in five hours.”
