A major incident has been declared after a double-decker bus overturned in Somerset.

A “significant number” of police, fire and ambulance crews have been sent to the scene in Bridgwater, officers said.

The bus was taking workers to Hinkley Point C nuclear power station at the time of the incident.

A motorcyclist was also involved.

A total of 70 people were on board when the bus “rolled over”, Devon and Somerset Fire and Rescue Service confirmed.

Multiple injuries have been reported, but no fatalities have been confirmed as of yet.

Avon and Somerset Police said officers were called at around 6am to the A39 Quantock Road following a “road-related incident involving a double-decker bus and a motorcyclist”.

“Closures are in place at the junction of Sandford Hill and Quantock Road,” it said in a statement.

“A significant number of police, fire and ambulance units are on the scene and a major incident has been declared.”

Police warned of ‘extremely icy’ conditions earlier

The A39 is a major thoroughfare around the Quantocks – linking the M5 with places like Minehead and Exmoor – and is also a key road for people who work at the nuclear power station.

However, Hinkley Point C has said travel to and from the site has now been suspended.

Confirming paramedics were dealing with the incident, Southwestern Ambulance Service advised drivers to find alternative routes and “take care” while travelling due to roads being icy.

Avon and Somerset Police had earlier warned about the “extremely icy and dangerous” conditions following freezing temperatures after receiving more than 100 reports of road-related incidents in five hours.

A total of 53 crashes were reported to the force between 6pm and 11pm on Monday, and injuries were recorded in seven of them.
