Drivers faced a 22-mile diversion as part of the A47 remained closed due to overrunning roadworks.
The major road was shut eastbound between Gorleston and Lowestoft from Beacon Park roundabout and Station Road.
A diversion was in operation, up to 22 miles long, via the A143 towards Diss, and A146 back to Lowestoft.
By 10am it had reopened.
Between Great Yarmouth and Lowestoft, resurfacing works have been taking place since early March, requiring overnight lane closures.
