The A142 near Newmarket has reopened following a crash between two vehicles on the flyover across the A14.
Suffolk police were called to the incident at 8:30am. Ambulance crews were also on the scene, although no injuries were reported.
Traffic was queuing on the A142 in both directions, with tailbacks in both the northbound and southbound directions, although this has now mostly cleared.
At its peak, it was backed up for almost two miles to the north, with queues extending to the Landwade Road Roundabout and Willie Snaith Road Roundabout in the south.
The A14 also experienced congestion, with substantial queues in the westbound carriageway, but these have also cleared.
