Traders say the roadworks which brought Lynn to a halt last week are damaging trade in Gaywood.
Roadworks on the junction of Tennyson Road were one of the reasons for the large traffic jams which were seen around Lynn on Friday last week.
One motorist reported taking 50 minutes to travel from North Wootton to Gaywood after problems were reported with the traffic lights on Tennyson Road and Edward Benefer Way.
Gaywood business owner Matthew Stevenson says the roadworks are causing problems for traders in the area.
Mr Stevenson said businesses are reporting a 50 per cent reduction in trade last week and blames the situation on the roadworks.
Mr Stevenson said: “It feels as if hardly anyone is coming. I noticed that the Tesco car park in Gaywood was just a quarter full. It is normally completely full.
“The roadworks are really not helping as we rely on passing trade and if people are put off coming into Gaywood then it is affecting us.
“The school holidays should be a busy period for us with people going away and coming back.
“On Friday, I had eight customers ring up to say that they could not get to us because of the traffic.
“Speaking to other traders, we have all noticed a difference in the last week or two.”
Norfolk County Council issued an apology to motorists who were stuck in traffic on Friday.
The vehicle activated sensor on the temporary lights in Tennyson Road malfunctioned.
A spokesman said: “We were aware of the congestion taking place in Lynn on Friday, and we apologise to all road users for the inconvenience.
“The issue is with the traffic lights attached to the roadworks on Tennyson Avenue, which should be controlled manually, and an engineer went to fix the problem.
“This unfortunately coincided with earlier problems with the traffic signals on Edward Benefer Way, which have been fixed.
“We apologise again for the traffic, and expect the problem to be resolved shortly.”
Last year, Gaywood suffered seven weeks of misery when a new pedestrian crossing was installed between Lynn Road and Queen Mary Road.
Butcher Michael Giffin decided to take early retirement and closed his shop after 10 years but blamed the decision on the lengthy roadworks that occurred.
