The A14 opened later this morning after being closed for more than seven hours.
The closure of the road at Bury St Edmunds between junctions 42 and 43 came at 3.36am today (November 14) after a lorry crashed into the central reservation.
The road was re-opened shortly before 11.45am but not before it led to a huge build-up of traffic in and around the town as vehicles were re-route off the main road and round the villages.
The A14 was closed in both directions between junction 43 at Bury St Edmunds and junction 42 at Westley which left the lorry straddled across both carriageways.
Highways England had advised drivers heading westbound that traffic was being diverted and should exit the A14 at junction 43, at the roundabout take the first exit and travel south on the A143. At the next roundabout take the second exit to continue south westerly on the A1302. Follow the A1302 to rejoin the A14 at junction 42.
Eastbound traffic is to exit at junction 42 and take the first exit onto the B1106 to Fornham All Saints. Turn right onto the A1101 to travel south easterly and cross under the A14. At the A143 roundabout take the first exit to rejoin the A14 junction 43.
A police spokesman said the driver of the lorry suffered shoulder injuries and was taken to the West Suffolk Hospital.
