A section of the A92 between Five Roads Roundabout and St Fort Farm in Fife is to undergo £135,000 of resurfacing works, starting on Sunday night.
The investment from Transport Scotland will address defects in the road surface and is expected to take four nights.
All work will take place between 7.30pm and 6.30am, and should be completed by 6.30am on Thursday.
A 10mph convoy system will be in place during working hours to ensure the safety of road workers and motorists.
The approaches of B946 to Wormit and A919 St Michaels will be closed overnight on Monday for safety reasons and a signed diversion route will be in operation.
All traffic management will be removed during the daytime.
Ian Stewart, BEAR Scotland’s North East Representative, said: “This £135,000 investment from Transport Scotland will greatly improve and strengthen this busy section of the A92, as well as create a smoother and safer journey for motorists.
“We’ve taken steps to minimise disruption for motorists as much as possible during the improvements by carrying out the project overnight, however we’ll do all we can to ensure that this project is completed as quickly and as safely as possible.
“We thank motorists for their patience in advance while our teams carry out these works on the A92. “
