A burst water main is set to cause up to a week of disruption for drivers in King's Lynn.
The issue caused Anglian Water to close Clenchwarton Road this morning with works also affecting neighbouring St Peter's Road.
Norfolk County Council has granted permission for the roads to be closed until February 6.
A diversion on the A17 via Station Road is causing long delays into West Lynn.
Drivers should also expect increased delays on the A47 Pullover roundabout.
