The Aberdeen Western Peripheral Route (AWPR) section from Craibstone to Stonehaven and Charleston in Scotland will open for traffic on 12 December 2018.
The new section of road includes the A90 between Stonehaven and Craibstone and the A956 between Cleanhill and Charleston.
With the opening of this section, north east road users will have access to 20 miles (32km) of new road.
Initially, Craibstone will be opened to traffic, and Stonehaven, Charleston, Deeside, Kingswells South and Kingswells North (A90 southbound exit slip road only) will be opened later.
Cleanhill Junction, linking the new A90 with the new section of the A956, will also be opened as part of this process.
However, there will be no access to the northbound AWPR from Kingswells North until the final section of road is complete.
The River Don Crossing is expected to be completed by December, subject to factors such as weather conditions.
Local road authorities have agreed on a route for traffic between Craibstone and Parkhill until the works at the River Don Crossing are completed.
Road users will be required to travel east from Craibstone using the A96, then north onto the A92 until Blackdog Junction and re-join the AWPR to Parkhill or continue north on the new A90 Balmedie to Tipperty section.
Permanent traffic signals will become operational at Stonehaven, Charleston, Deeside, Kingswells and Craibstone and they will be monitored to ensure the junctions are operating as anticipated.
Cabinet Secretary for Transport, Infrastructure and Connectivity Michael Matheson said: “This new section of road, which will make more than 85 per cent of the project open to traffic, will immediately make a tremendous difference to road users across the north east.
“It will provide thousands of drivers every day with a range of benefits, including improved journey time reliability, better local access and reduced congestion, while safety will also be enhanced.
“It will also improve air quality and reduce traffic volume in Aberdeen City, making pedestrian and cycle travel around Aberdeen easier, safer and a more enjoyable experience.”
Previously, road has been opened between Balmedie and Tipperty in August 2018, Parkhill and Blackdog in June 2018 and the Craibstone Roundabout and Dyce Drive section in September 2016.
