Average speed cameras on a busy north-east commuter route will be switched on tomorrow.
The 50mph limit at Charleston on the A90 Aberdeen to Dundee road will be enforced when the devices go live.
The cameras have been in place for months, but had to be tested before being switched on. The scheme was further delayed after a generator was stolen from a nearby work site earlier this month.
The cameras are being rolled out to protect the construction crews working on the Aberdeen bypass workers from speeding motorists.
Similar cameras arealready being used at the site of the bypass work at Balmedie.
A Transport Scotland spokesman said: “These cameras are similar to the existing average speed cameras on the A90 between Blackdog and Balmedie, which have been operational since July 2016. The works at Charleston took a step forward towards the end of last year following the introduction of the new traffic management measures.
“These were implemented while works are underway, including a 50mph speed restriction, which was introduced to improve the safety of road workers and road users.
“When the average speed cameras become operational, the speed restriction will remain unchanged at 50mph. However, the cameras will help to ensure that this speed restriction is observed.”
Councillor Ian Mollison has previously welcomed the speed restrictions amid the ongoing construction upheaval.
Last night, he said: “It will be most welcome to get them operating and will stop people zooming along the road at 70mph.
“There have been several near misses at the Wellington slip-road where the merge has been shortened due to construction works.”
Arron Duncan, manager for the North Safety Camera Unit added: “Average speed camera systems across the country typically have a high compliance rate and we hope for the same result at this location.
“I would urge all drivers to remain within the 50mph speed limit for their own safety and the safety of all road users.”
