Dean Myhill, area highways manager at Lincolnshire County Council, said residents complained the double-yellow lines on a street in Louth were too wide and brightly colored for the area, which is a protected conservation area, the BBC reported Tuesday.
The spokesman said workers will replace the lines with narrower markings colored a light primrose.
Myhill said the cost of repainting has not yet been established.
"In a conservation area such as Upgate in Louth, we use a more subtle color for our yellow lines and paint them about half as wide," Myhill said. "This is to make sure our road markings help to protect the town's unique character. In this case, we have made a mistake and painted our standard yellow lines. We apologize for this error and will look to paint the correct lines."
