Motorists driving through the heart of Lowestoft face up to five weeks of disruption from Monday as major work starts to repair a broken and collapsed sewer at Station Square.
The �130,000 repair work will see vehicles prevented from turning right from Station Square into Waveney Road as the middle lane of the A12 at Station Square will be closed.
Instead of being able to turn right motorists will be diverted via Denmark Road, Katwijk Way, St Peter's Street, Artillery Way, Old Nelson Street and Battery Green Road.
The middle lane of Station Road is being closed under a Highways Agency order and the organisation says it could be closed for up to five weeks.
Anglian Water is carrying out the repairs on the broken sewer which is about 5m below the surface of the road.
Antony Innes, a spokesman for Anglian Water, said: 'Work will be starting next week on a �130,000 project to repair a broken sewer under the A12 at Station Square in Lowestoft.
'It is anticipated that work will take around four weeks to complete due to the depth of the sewer, some five metres beneath the road.
'We understand that this work will cause some disruption and we are sorry for that.'
