A major stretch of Aberdeen bypass is to open on Wednesday.
The route, between Stonehaven and Craibstone, including the Charleston section, is around 20 miles long.
To aid with the opening Police Scotland will be phasing the opening of the new junctions.
The Craibstone junction will be the first to open – early on Wednesday morning, followed by Stonehaven, Charleston, Deeside, Kingswells South and Kingswells North.
The Cleanhill junction, which links the bypass and the new road to Charleston, will open as part of this process.
The last section of bypass that opened – Parkhill to Blackdog – was fully operational by around 5.30am, however, Transport Scotland cannot give an exact time for Wednesday, saying it is at the discretion of Police Scotland.
At Kingswells North, only the A90 southbound slip road will be opened for safety reasons. This will limit traffic heading northbound on the AWPR until the road is complete.
New permanent traffic signals at Stonehaven, Charleston, Deeside, Kingswells and Craibstone will be switched on overnight Tuesday ahead of the new section opening.
These will be monitored to ensure they are operating as expected, but these may require tweaks until “optimum phasing” is achieved.
The speed limit for the new stretch is planned to be 70mph for cars, 60mph for smaller goods vehicles, such as Ford Transit and Ford Connect types, and 50mph for Heavy Goods Vehicles.
A specific route has been set up and a agreed for motorists travelling between Craibstone and Parkhill.
According to Transport Scotland: “Road users should travel east from Craibstone using the A96, then northbound onto the A92 until they reach Blackdog Junction where they can re-join the AWPR to Parkhill or continue north on the new A90 Balmedie to Tipperty section.
“The reverse journey should be used for those wishing to travel south to Craibstone.”
A December opening has been targeted for the final section, but contractors and Transport Scotland have said this is subject to a range of factors, including weather.
What restrictions will be in place when it opens?
Here’s a breakdown of all the expected restrictions in place ahead of the opening of the new stretch of Aberdeen bypass
A90 Craibstone junction Northbound
Temporary traffic management will be in place on the new A90 northbound between Kingswells North Junction and Craibstone Junction to guide road users safely off the A90 until the remainder of the AWPR opens to traffic.
As these traffic management measures will begin in the vicinity of Kingswells North Junction, the northbound slip road onto the A90 at Kingswells North Junction will remain closed for safety reasons.
To join the AWPR northbound to Craibstone, road users should travel to the Kingswells South Junction or continue to use existing routes which are expected to be quieter. Road users travelling southbound from Craibstone will be able to leave the A90 at Kingswells North using the exit slip road.
Traffic routing between Craibstone to Parkhill and Blackdog
The signed route to direct traffic from Craibstone to Parkhill has been agreed with the local roads authorities.
Road users travelling east from Craibstone should use the A96 and onto the A92 (previously the A90) until they reach Blackdog Junction where they can re-join the AWPR to Parkhill or continue north on the new A90 Balmedie to Tipperty section.
The reverse journey should be used for those wishing to travel south to Craibstone. This will be in place until the works at the River Don Crossing are complete and the remaining AWPR section opens to traffic.
Overnight lane closures
Overnight lane closures will be required on several locations on the road network for essential transition works prior to this major section of the AWPR opening to traffic.
These lane closures, which will allow signage and road markings works to take place, will begin at 8pm on Tuesday 11 December and will be removed before the new A90 opens to traffic.
The roads affected are the A92 at Stonehaven and Charleston, the A93 North Deeside Road, the A944 at Kingswells and the A96 at Craibstone Roundabout.
Douglas Laird, project manager for the AWPR/B-T project at Transport Scotland, said: “We understand that the people of the north east are keen to use the AWPR as soon as possible but we have to remind people that this is a major piece of infrastructure which is opening to traffic.
“This means that significant changes will be implemented overnight on other trunk roads, such as the A96, and local roads across the north east network to accommodate new junctions and new temporary speed restrictions.
“It is therefore imperative that they not only drive with more caution for their own safety but also consider the safety of other road users’ and road workers alike.
“There may be a degree of uncertainty amongst some drivers and they should be prepared to react appropriately to ensure journeys can be completed safely.
“We also kindly request that road users observe all signage and modify their driving accordingly to suit the prevailing road and weather conditions, such as low sun or rain.”
Police Scotland Chief Inspector Stewart Mackie, who is responsible for road policing in the North, said: “This new road is a great asset for the north east and will make the journey from the north to south of the city considerably quicker.
“From a police response perspective, it will allow us to respond more effectively.
“The bypass is designed to the highest safety standards and as such we would hope that we see a reduction in casualties and collisions in and around Aberdeen as a result.
“This is a brand new road and it will take people time to familiarise themselves with the road and the new junction layouts and approaches.
“When you first use the road please leave plenty of time for your journey.
“We’re committed to making sure people use the road safely so our officers along with staff from the Safety Camera Unit will be conducting high visibility patrols and speed checks along the entire length of the route.”
Arron Duncan, Area Manager of the North Safety Camera Unit, added: “The AWPR is a long awaited and highly welcomed inclusion to the North East roads network.
“The North Safety Camera Unit will assist our police colleagues in establishing the road as a safe, enjoyable route, by carrying out a period of short term deployments in order to further remind motorists of the speed limits and encouraging them to travel within them, particularly at a time when drivers are trying to familiarise themselves with the new layout and junction movements.
“Whilst the maximum speed limit on the route for cars is 70mph, 60mph for smaller goods vehicles, such as Ford Transit and Ford Connect types, and 50mph for Heavy Goods Vehicles, drivers should be aware that vehicles may be travelling much slower than these maximum limits as they try and interpret the junction layout ahead.
