Three weeks of overnight closures on the A12 have begun amid work to resurface the carriageway.
The closures are in place between the exit and entry slip at junction 25 at Marks Tey in the northbound carriageway.
The overnight closures are taking place on weekdays between 9pm and 5am until Friday, March 17.
While the carriageway is closed a diversion route will be in place.
Drivers will exit the A12 at junction 25 and travel over the roundabout before re-joining the A12.
It comes as National Highways are also carrying out overnight repairs on the A14 between Bury St Edmunds and Ipswich.
