POLICE are still attempting to piece together an incident which saw the A34 southbound carriageway shut for nearly a entire day late last week.
A collision involving two lorries and an Audi led to an diesel spill on the road, shortly after 6.30am on Friday morning.
It led to huge queues around the area, with diverted traffic being gridlocked for hours.

No one was injured in the incident, but the carriageway did not reopen until around 12.30am on Saturday.
Thames Valley Police are now appealing for witnesses following the collision, between the Peartree and Wytham junctions.
A section of the road required resurfacing, with Highways England saying 'extensive' work was needed after 500 litres of fuel covered the road.
Investigating officer PC Kevin Crick, of the Joint Operations Unit for Roads Policing, said: “I would like to speak to anyone who witnessed the collision or who saw the lorries and a dark-coloured Audi just prior to the collision.
“If you saw what happened or have any dash-cam footage of the incident, please contact police.”
Anyone with any information is asked to call 101, quoting reference 43190004823, or make an online report.
