The Highways Agency is urging motorists to avoid areas of the A34 this morning.

Heavy delays have been reported in both directions of the road through the county, but the agency said it is continuing to grit the carriageways.

A spokesman said: “Highways Agency advice is to avoid the A34 from the A415 junction near Abingdon to the A4130 near Milton. There are delays northbound from the M4 at Junction 13 near Chieveley to Ilsley and southbound from Abingdon for around four miles.

"Vehicles can use the M4, M40 and M25. HGVs are finding it difficult to travel and are getting stuck.

"A gritter is patrolling the stretch with the police to clear incidents."

The latest travel reports say the dual carriageway is closed in both directions, and there is an accident on the southbound carriageway of the M40 at junction 10 at Ardley.

There is also a broken-down lorry on M40 southbound between junction six at Watlington and junction five at Stokenchurch.

London Road at Headington, near Green Road roundabout, is closed (9.50am) in both directions because a vehicle has broken down.

The M40 is closed northbound between junction 10 at Ardley and junction 11 at Banbury because of an obstruction on the road.

Stagecoach and the Oxford Bus Company have cancelled a number of services, and First Great Western are running a reduced service between Henley and London Paddington.

Alison Brumfitt, a spokesman for South Central Ambulance, said: “There have been a number of road traffic accidents, but most drivers seem to be getting the message that they need to drive carefully, and should not go out unless they absolutely need to.”

First Great Western services are running as normal into London Paddington despite the snow, according to the firm’s travel website.

The 10am service from Oxford to Paddington is cancelled, but no further delays have been reported so far into the capital, apart from a reduced service between Henley and London. FGW spokesman Ellie Banks said all other services from Oxford were running as normal.
