A Preston road dubbed the city's very own 'Golden Mile' has generated nearly £300,000 worth of speeding fines in just two-and-a-half months.
Almost 5,000 motorists have been snared by four speed cameras on the two-mile stretch of the A583 in just 75 days.
The temporary cameras near roadworks at Riversway have zapped 4,930 drivers since they were installed in July.
The fines will go straight to central government coffers rather than to Lancashire County Council, which is carrying out the maintenance work on the road.
Now questions have been raised about the number of fines dished out for just one road when around 100,000 people received tickets across the whole of Lancashire in 2005-6.
The RAC Foundation said the cameras are important to prevent accidents with the road workers but pointed out that because of the large numbers of drivers getting tickets the cameras were not being signposted properly.
A spokesman for the Lancashire Partnership for Road Safety, which operates the cameras, said they were there to protect roadside workers and motorists and while admitting that nearly 5,000 drivers had been detected, the number was just 0.2% of vehicles which had gone through the area.
