Average speed cameras along the A90 are to extended to Stonehaven.
The cameras will be installed later this week as part of safety precautions taken as the work on the Aberdeen bypass continues.
There is a temporary 50mph speed limit on the stretch of road until works complete on the AWPR.
A Transport Scotland spokesperson said: “The works at Stonehaven will substantially increase over the coming weeks.
“To enhance the safety of the rising number of road workers on the A90 at Stonehaven, many of whom will be working in close proximity to road users in this area, it is necessary to use additional safety measures on this section of road.
“The use of average speed cameras will also protect road users, where construction operations adjacent to or beneath the road are not always visible to them.
“In addition to the proven safety benefits of average speed cameras, their deployment in major road works schemes demonstrates their ability to improve traffic flow and journey time reliability.”
Arron Duncan, North Safety Camera Unit Manager said: “The benefits obtained for road workers and road users through the deployment of average speed cameras during construction works such as the AWPR/B-T is well proven.
“I would therefore urge drivers to rigidly adhere to the posted speed limit in force as the ultimate responsibility always lies with them to comply with any restrictions in place.
“Compliance levels for speed is generally very high in Average Speed systems but those who do fail to comply will ultimately have to deal with the consequences of that risk-taking decision through the enforcement measures in place.”
