'Lengthy' A1067 Norwich to Fakenham roadworks detour
Motorists travelling between Norwich and one of Norfolk's market towns will face a journey of almost double the usual distance when roadworks begin.
Major work to repair the A1067 Norwich to Fakenham road, which was damaged during the winter, begins on Monday.
It will mean closing the road at Lenwade for nine days.
The county council has suggested a "lengthy" 46-mile diversion via Swaffham. The A1067 route between Norwich to Fakenham is about 25 miles.
The road closure was expected to last three weeks but has been shortened by using excavated materials in the reconstruction of the road surface.
"It is not possible to carry out the work safely without a period of closure," a spokesman said.
Once the closure has been lifted work will continue using temporary traffic control.
The road should be completely clear in about two weeks, the council added.
