A major Peterborough junction was shut for nearly four hours after a motorist suffered a stroke.
Police and ambulance crews were called to the two car collision at the junction of the A47 and A16 at 5.48pm on Wednesday, August 1.
The crash involved a Citroen C1 and a Nissan Qashqai.
A police spokesman said "One person suffered serious but not life threatening injuries", but the Peterborough Telegraph has since been informed a woman suffered a stroke during the incident and is now recovering.
The road was closed and not reopened until about 9.15pm
