Motorists are being advised to avoid Oundle Road in Woodston after three people were hurt in a two car crash.
The crash happened near the BP garage at the Sugar Way junction at about 4.15pm, and involved a Mercedes and a Citroen.
The road was blocked both ways as a result of the crash.
An East of England Ambulance Service spokesman said: “We were called just after 4.15pm to the road traffic collision.
“There were three patients, two men and a woman. None of them seen to have been seriously injured.”
The spokesman said all three would be taken to hospital as a precaution. A Cambridgeshire police spokesman said motorists are advised to avoid the area while the wreckage is cleared away.
