A tunnel in Norway was been closed for the past six days - due to a cheese fire on a truck.

About 27 tonnes of caramelised brown goat cheese caught alight while it was being driven through a 3km tunnel near Narvik last Thursday, BBC News reported.

Officials said the tunnel is badly damaged and will remain closed for several weeks. Smouldering toxic gases were slowing the recovering operation.

Police officer Viggo Berg told Reuters the high concentration of fat and sugar in the cheese, a delicacy known as Brunost, made it burn "almost like petrol if it gets hot enough".


Kjell Bjoern Vinje, of the Norwegian Public Roads Administration, said it was the first time cheese had caught fire on a Norwegian road in his 15 years with the administration.

"I didn't know that brown cheese burns so well," he told Reuters.

No one was injured in the blaze.
