Update: 05:30am - Thursday 21 September

The A34 has fully reopened after a lorry overturned and crossed the central reservation.

There was heavy traffic through Winchester city centre for rush hour yesterday as the closure of the A34 caused tailbacks.

During a major recovery operation, the driver was extracted from the vehicle, and taken to hospital with an arm injury.

However another stretch of the road has been closed near to the M4, following a vehicle leaving the carriageway.

Motorists are being warned that a major route in Hampshire has been closed this morning due to an overturned lorry.

The A34 has been shut between the M3 near Winchester and the A303 due to the incident.

It is likely to remain closed for 'much of the day', Hampshire Police said. This is due to the complex recovery work and the need to resurface the road.

National Highways confirmed emergency services are on scene. Work has taken place to extract the driver from the vehicle.

The lorry has come to a rest across both carriageways and a significant amount of diesel and oil has been spilt.

In a statement Hampshire Police said: "We are currently at the scene of a collision on the A34 northbound, close to the M3 junction, involving a HGV.

"The road is closed in both directions and a diversion is in place. We expect the road to be closed for the majority of the day and ask road users to please avoid the area wherever possible and allow extra time for your journey.

"The driver of the HGV has sustained an injury to his arm and has been taken to hospital for treatment.

"We apologise for any disruption while we deal with this incident and ensure that the road is safely cleared, and we thank you for your patience."

In a statement, National Highways said: "It was reported through to National Highways at approximately 03:50 that a Artic Lorry has overturned and come to rest across both carriageways. 

"Fire Services are on scene to extract the driver out of the vehicle, and ambulance services also remain on scene.

"It was also reported that a significant amount of diesel and oil has spread across the carriageway, so emergency clear up crews will also be required to attend the scene once the vehicle is recovered.

"National Highways have resources in attendance to assist with traffic management. Traffic within the closure will be released as soon as possible."
