A town council was shocked to discover that setting up new flashing low bridge signs on the approach to its town could cost as much as £20,000.
Kevin Hunter, Needham Market town clerk, said new flashing visual or audio signalling was needed along Coddenham Road to warn lorry drivers of the 2.5 metre low bridge next to Needham Lake.
“There have been a lot of incidents of lorries going down as far as the bridge and having to reverse and turn around,” he said.
“It is a danger for road users and for pedestrians.”
A Suffolk County Council spokeswoman confirmed the estimated cost of the sign.
She said: “Detailed design and analysis would have to occur before a final costing takes place.
“We are currently working with the town council to develop a wider transport plan for Needham Market as a whole.”
