Norfolk traffic survey: Nine-mile tail back on bypass
Norfolk County Council has apologised after a traffic census caused nine-mile tail back during the rush hour.
The survey of traffic on A47 Norwich Southern Bypass was lifted early because of the congestion.
It was the last of 30 surveys that caused traffic problems in and around Norwich since 5 November.
It began at 07:00 GMT on Wednesday and was suspended at 09:30 GMT because the queues had become far worse than anticipated, a spokesperson said.
The council will assess information already obtained and has decided not to resume the survey.
"Norfolk County Council apologises for the inconvenience caused by the surveys carried out in the Norwich area during November," a statement said.
"Origin and destination information is essential to help plan travel and transport improvements.
"This has to be obtained from people using the road, either through on-the-spot interview, or via pre-paid survey postcards."
