Two people have been taken to hospital after a lorry crash blocked the A14 on the outskirts of Suffolk.
An overturned lorry has led to a large section of the A14 near Newmarket being closed this morning.
The road is closed in the eastbound direction from junction 31 for the M11, to junction 36, Nine Mile Hill.
Cambridgeshire Police said that five vehicles - two lorries and three cars - were involved in the incident.
A spokesman said that the injuries sustained are not thought to be life-threatening.
Traffic is now being diverted on the A1304 through Newmarket, with a three-mile queue reportedly taking 25 minutes to get through.
Cambridgeshire police are in attendance.
