There were heavy delays on the A12 northbound and the A14 eastbound near Ipswich after a vehicle broke down.
Emergency services were called to the Copdock Interchange at 9.44am on Friday to reports of a broken-down coach.
The coach was blocking the roundabout and recovery attended to clear the road.
The roundabout is now open and the AA traffic map suggests traffic is clearing in the area.
