DRIVERS were being warned about serious delays on the A34 near Oxford today after traffic was diverted from the M40 following a fatal crash.

There were lengthy tailbacks on the M40 after the motorway was shut in Buckinghamshire, with reports of delays 20 miles at junction nine near Weston-on-the-Green.

The morning crawl to work was made worse by other problems on the A34 near Didcot and the B4100 at Baynards Green.

The problems started after a woman died following a fall from a motorway bridge.

Police closed all three lanes of the London-bound M40 between junctions five and four to allow officers to fully investigate the incident.

Two lanes were later reopened and traffic is beginning to flow. The inside lane is expected to remain closed for the foreseeable future.

Sgt Steve Underwood, of Amersham police, said: "A number of witnesses have come forward, however I would urge anyone who has any information or who was driving along this stretch of motorway at the time to contact me so we can piece together exactly what has happened."

Anyone with any information should contact Sgt Underwood via the Police Enquiry Centre on 0845 8 505 505. If you don't want to speak to police or leave your name, call the charity Crimestoppers on 0800 555 111.
