A call for traffic lights at an accident blackspot has been renewed after two more collisions last weekend.

Two cars turning out of the Marsh Gibbon road on to the A41 Bicester-Aylesbury road, by the Blackthorn railway bridge, were struck by cars travelling from Bicester.

The bridge has seen numerous accidents over the years.

In one of the worst, a lorry hit the bridge and toppled over on to a van, killing the driver.

After many complaints, the road under the bridge was lowered, to prevent lorries striking the span over the A41.

Concrete barriers were also installed to stop vehicles hitting the brickwork at the sides of the bridge.

Michael Hall, chairman of the A41 working party, said: "When the road was lowered, ducts to take traffic light cabling was installed, so there would not need to be any more roadworks."

Mr Hall, of Clements Lane, Marsh Gibbon, near Bicester, said: "We do feel lights would help to control traffic. We also need the junction of the Marsh Gibbon road re-aligned, so drivers have better visibility towards Bicester."

He has heard more minor improvements were scheduled to be introduced soon.

David Keen, A41 route manager for the Highways Agency, told him in a letter that a skid-resistant surface and cross-hatching would be placed in the middle of the road.

Mr Keen also said talks were continuing with Thames Valley Police, over the prospects of reducing the speed limit from 60mph to 50mph close to the bridge.

County councillor Catherine Fulljames, who covers the area, said: "Anything more that could be done at the bridge would help. I believe traffic lights would be a great assistance."
