Carriageway and footway maintenance works are set to take place on Low Road Bridge in Spalding, starting on Monday, April 3.
Weather permitting, the work will be completed on Friday, April 14. For safety, the road will be closed for the duration of the works, with traffic diverted via Low Road, Queen’s Road, Holbeach Road, A151 and A16.
A highways spokesperson said: “The surface of the bridge has become uneven over time, so we are going in to replace it.
“We apologise for any inconvenience caused, and advise motorists to allow extra time for their journeys.”
