The March bypass was closed for two hours at the busiest time of the day yesterday following a serious collision.
A black Fiat Punto and silver Audi A4 were in collision on the A141 at its junction with Gaul Road at 5.33pm.
Five people were taken to hospital for treatment, two with serious, but not life-threatening, injuries.
The road was closed until 7.30pm.
PC Matt Smart said: “This happened at a busy time of day and I would appeal to anyone who saw the collision, or either vehicle prior to it, to call police.”
Anyone with any information should call the Roads Policing Unit on 101.
