THE A420 at Faringdon is blocked both ways due to a serious collision involving three vehicles. 

Major delays are expected. 

A Thames Valley Police spokeswoman said: "We were called at 7.55am to the A420 in Faringdon where a Mercedes and a Vauxhall Corsa were involved in a collision.

"One of the cars is in a ditch.

"The road has been closed and traffic is being turned back."

A South Central Ambulance Service spokeswoman said: “We were called at 7.53am to a three vehicle road traffic collision.

“Three ambulance crews and an ambulance officer were sent to the scene and two patients were taken to the John Radcliffe Hospital.”

The A417 is closed at East Challow for bridge maintenance so traffic diverting along this road will not be able to access to the A338.
