Drivers warned A375 between Honiton and Putts Corner impassible.

Teams from Devon County Council are working round the clock to keep traffic moving following heavy snowfall overnight.

The County Council says most major routes are passable with care but conditions are hazardous, particularly off the main salting network, and there is some disruption on routes around Devon.

The A375 between Honiton and Putts Corner has been closed as it is impassable.

The Highways Agency has reported that the A303 has re-opened after an earlier two vehicle accident at Marsh, and the A35 between Honiton and Axminster has now re-opened after it was closed in both directions earlier because of a jack-knifed lorry.

The county council is advising people to take extreme care if they are travelling today and to expect problems on higher ground, although conditions should be easing during the day.

Councillor Stuart Hughes, Devon County Council cabinet member for highways and transportation, said: “County council teams have been working hard throughout the night gritting and ploughing main roads on our precautionary salting network.

“The conditions are challenging this morning and most major routes are passable with care, but we are dealing with extremely hazardous conditions on some roads such as the A361, and we would ask people to bear with us.

“Please do not make unnecessary journeys if it is not essential, but do take extreme care if you are travelling and where you can please keep to the main A and B roads and off of the minor roads.”

A number of schools have also been forced to close.
