Double painted yellow lines drawn using a trial paint have broken up on a road in Stamford.
Highway workers from Lincolnshire County Council have now unsuccessfully marked the parking restriction lines in St Mary’s Place twice.
The first set of wobbly lines were removed in November after complaints about the “shoddy” job. Now the replacement lines, using an experimental paint, have failed to stick to the cobbles.
Head of Highways West Brian Thompson, said: “We know that Stamford’s cobbled streets are an important landmark for its residents and visitors alike.
“We also want to protect its appearance by ensuring that parking restrictions are enforced in the area.
“However, applying the usual methods of laying yellow lines with liquid paint is difficult on this tricky surface.
“We used these lines as a trial to assess their durability here. As it hasn’t worked, we’re already looking into alternative solutions and will get these in place as soon as we possibly can.”
The lines are to make parking restrictions clear to motorists now wardens are patrolling the town.
