A fire at the Alverton Manor Hotel in Truro is causing traffic chaos in Truro.
One lane of Tregolls Road in Truro is still closed after a fire ripped through the Alverton Manor Hotel this morning, causing damage to a newly refurbished function room.

Cornwall Fire Service chief incident officer Guy Herrington said that a “significant amount of damage” has been sustained to roughly a quarter of the hall.
No one was injured in incident and fire crews have praised quick thinking staff for evacuating guests promptly.
Tony Wong, a technical support manager at the hotel, said: “I walked in to the room at 9.05 because I could smell smoke and then I started off the fire alarm.
“It was scary and the room has only been recently refurbished.”
Mr Wong said that a wedding booked at the hotel this weekend which will no longer be able to take place.
