The A90 near Brechin will see improvements to a 1.4 kilometre stretch between Keithock and Stracathro Services.
The works being undertaken by BEAR Scotland on behalf of Transport Scotland will involve resurfacing of both northbound lanes.
Commenting on the works, Andy Thompson, BEAR Scotland’s North East Unit Representative said: “These works will repair a number ruts, cracks and potholes which will improve the general condition of the road and enhance ride quality for motorists.
“The works are being carried out overnight to minimise delays.”
