Part of A3 closed after emergency incident near West Sussex / Surrey border
Drivers are facing delays after the northbound A3 Hindhead Tunnel was closed, following a road traffic collision.
National Highways said the closure was put in place, between the A333 at Hazel Grove and the A283 at Milton, while emergency services respond to the incident.
Surrey Police, Surrey Fire and Rescue Service and South East Coast Ambulance Service are all in attendance.
Motorists have been warned to expect disruption and allow extra time for journeys while the closure remains in place, near the West Sussex / Surrey border.
A diversion route has been set up for northbound traffic, with drivers being directed off the A3 at the Hazel Grove interchange before following the A333 and A287 towards Farnham.
The diversion continues via the B3228 West Street and A325 to the Coxbridge roundabout, before traffic is directed along the A31 Farnham bypass to re-join the A3 near Guildford.
National Highways advised motorists to plan ahead, consider alternative routes or delay journeys where possible.
