CRASHES and temporary traffic lights caused travel chaos in and around Oxford this morning, with major delays on the A44, A34 and M40.

The roads are now clear following rush hour, but some people spent a large chunk of their morning sat in queues. 

Traffic was slow on the A34 southbound all the way from the Botley Interchange to the Wendlebury Interchange, with nine-mile queues at the height of disruption. 

The A420 was extremely slow in the Cumnor area, with Botley Road also badly congested.

Bicester Advertiser:

Delays on the A44 southbound have eased following an earlier crash at Yarnton, which blocked part of the road until 8.45am.

Two cars also crashed on Marston Road in Oxford, at Headley Way, causing delays towards Oxford.

Oxford Bus Company tweeted just after 9am, announcing that its City 5 service would not be able to serve the rail station due to 'severe congestion' in the area.

In an earlier tweet, it blamed the closure of Worcester Street for the congestion.

One woman tweeted to say it had taken her an hour this morning to get from the bottom of Cumnor Hill to the McDonald's traffic lights on Botley Road.

Another said a 28-mile journey had taken almost two hours.

Elsewhere in the county, there were reports of an overturned vehicle in Frilford, causing delays on the A338. 

Motorists also faced major delays on the M40 southbound this morning, following a crash between Lewknor and Milton Common, but those queues have since cleared.

There were queues on the A418 both ways in Thame, at Kingsey Road, due to roadworks.
