The Orwell Bridge has fully reopened after a lorry's trailer detached on the carriageway.
Police closed one lane of the A14 westbound, between Nacton and Wherstead, shortly after 3.20pm – after the lorry's trailer detached just after the crossing.
The disruption caused knock-on effects across the town, with major routes in and out of Ipswich seeing heavy traffic.
Highways England announced the closure had been lifted shortly after 6.20pm.
