A new cycle path linking Sudbury and Great Cornard is an “accident waiting to happen” due to the confusing nature of the signs.
Cyclists and green campaigners have welcomed the route along Cornard Road but have been left scratching their heads because the signs do not indicate which side a cyclist and pedestrian should take.
Lynda Coots, from York Road, Sudbury, said the signs were so unclear they could cause an accident.
“Whoever did this needs their head testing, because there are safety issues,” said Mrs Coots, a carer.
“I have always cycled and think this is a brilliant idea in principle, but it has not been done in the right way.”
The cycle route has been introduced thanks to a donation from Sainsbury’s as part of a section 106 agreement – money paid by the company to offset the impact of its supermarket in Cornard Road.
Mrs Coots said on busy days, the path could not be used by cyclists, as too many pedestrians were in the way.
“On market day and Saturdays, there is no way you can cycle down there as it is an accident waiting to happen,” she said.
“You have to get off and walk and that defeats the object. I just want people to be aware of the problem.”
Sudbury and Great Cornard councillor John Sayers said he had been contacted by a number of people confused by the markers.
A spokeswoman for Suffolk County Council, which carried out the work, said the signage was correct and was there to make both cyclists and pedestrians aware that there was “shared usage of the path”.
