Application will soon be submitted to extend the working hours to build the Aberdeen bypass.
The contractor behind the Aberdeen Western Peripheral Route (AWPR) will submit applications to Aberdeen City Council and Aberdeenshire Council to extend its working hours across the project.
A Transport Scotland spokesman said: “The project remains on target for completion in winter 2017.
“As part of a consultation exercise, the contractor is discussing with both local authorities the timings of these potential extended working hours.
“The contractor is also consulting with the local community and, if its applications are successful, will carry out a ‘neighbour notification’ exercise to ensure that residents in the vicinity of these works are advised of the changes.
“If approved, these extended hours will enable the contractor to take advantage of daylight hours and undertake its works.”
Extended working hours were put in place last year on the southern section of the route, Stonehaven to Charleston.
Transport Scotland said it allowed the contractor increased flexibility to carry out the works.
North-east Liberal Democrat MSP Alison McInnes today called for more openness about plans to extend the working hours.
She said: “I know that residents in the southern part of the project around Maryculter in particular were most unhappy after council officers approved seven day working in the weeks up to Christmas.
“People should be entitled to expect one day of rest so that they can enjoy their gardens and homes in peace.”
