Average speed cameras have been installed on a Norfolk trunk road that has a history of fast driving, injuries and fatal crashes. National Highways reduced the speed of the A47 Acle Straight, east of Norwich, in April from 60mph to 50mph (96km/h to 80km/h) to improve safety, says the BBC.

However, Adrian Clothier, engineering team manager at National Highways, said there were unavoidable delays meaning the monitoring equipment was not fitted in the summer as had been planned.

“We have overcome some challenges around the poor ground conditions when installing the new speed cameras and installation will be completed this week, although calibration will need to be carried out,” he said.

“The 50mph limit, however, is in place and is enforceable by the police.”

Cameras have been fitted at the east and west ends of that stretch of the road, with another opposite the Branch Road junction from Halvergate and another between Branch Road and Great Yarmouth.

The road has been closed several times since the speed limit was reduced owing to crashes.

The campaign group The A47 Alliance has criticised the limitations of the safety measure and said the road should be dualled.

Graham Plant, from the group and also Norfolk County Council’s cabinet member for transport, said more needed to be done to improve safety and they were “still campaigning”.

“I can’t argue with the fact if their records say its going to improve safety, because I don’t want people dying.

“But reducing the speed isn’t the answer. The answer is dualling and until they dual it there will continue to be accidents on the Acle Straight.”
