Northbound traffic will leave the A90 at Invernettie Roundabout, following the A982 South Road and taking the first exit at the roundabout onto the A950 to rejoin the A90 at Howe o’Buchan Roundabout. Southbound traffic will follow the route in reverse. The Cairntrodlie and Nether Kinmundy junctions will be closed during the works. Access for Cairntrodlie will be via local roads in Peterhead. Access for Nether Kinmundy will be via the A950 Blackhills.
Upgrading and replacement of existing High Voltage cables
TTLs to be manually controlled to optimize traffic flow from roundabout.
In preparation for the construction of the new converter station, enabling works will include:
Two new permanent access roads with new junctions on the U66, along with a temporary road through the site for construction traffic.
A site car park and erection of temporary site offices for use during construction.
Construction of a new cable sealing end compound, and removal of two existing 132kV towers including an existing cable sealing end compound on the existing overhead line that crosses the site.
Ground investigation works.
Undergrounding of the existing 11kV overhead line within the converter station land boundary. A new 11kV connection will be installed into the site, running parallel with the A90. This will require periodical temporary traffic lights on the A90 from the U66 junction to the Invernettie roundabout, until March 2024.
