Lincolnshire County Council has promised minimum disruption as road resurfacing and footpath repairs take place in Spalding later this month.
Works will take place first in the Sheep Market for two days, followed by five weeks of work in Market Place and Hall Place.
Sheep Market will be closed to traffic for essential resurfacing work on Sunday and Monday, August 21 and 22.
The road will be closed to through traffic and there will be no access available to the district council car park during the works. Access will be maintained for residents.
The works have been planned to take place on those days to minimise disruption to businesses and residents.
The street is a one-way street with no diversion route and advance signs will be placed on site seven days before the work starts, and all premises and businesses in the area affected will be notified by letter.
The following week, a programme of repairs to footpaths and roads is due to take place in Spalding Market Place, with areas of block paving due to be repaired throughout the pedestrianised area.
The work will start on Tuesday, August 30 and is expected to last five weeks. Work has been timed to cause minimum disruption to businesses, and will also avoid any community events planned to take place within the town centre.
All shops and businesses will be accessible during the works and they will be receiving letters with more details.
Provision has been made for alternative sites for parts of the regular Tuesday and Saturday market if the works mean that they have to be moved temporarily. This has been agreed with South Holland District Council markets officers.
