The A9 will be closed for three nights next month as a final set of bridge beams are installed.
Drivers have been advised to allow extra time for their journeys during the closures that will take place between 8.30pm to 6am on Wednesday 12 and Thursday 13 in February and from 10pm to 6am on Friday if needed.
The closures are in place for the installation of precast concrete beams at Gelly overbridge as the A9 dualling: Luncarty to Pass of Birnam project reaches its final stages.
Work will take place over the existing carriageway and more than half of the deck area will be landscaped to provide a safe route for a variety of wildlife to safely cross over the A9.
A number of ‘green bridges’ have been built on projects in Scotland including three on the recently opened Aberdeen Western Peripheral Route.
The Gelly overbridge, north of Bankfoot, is the most northern structure on the project and will provide access to adjacent landowners and residents.
February 14 has been included as a contingency date as the work will be weather dependent as heavy lifting operations are sensitive to high winds.
The closures may be postponed if poor weather is forecast.
In the event that the works are completed on the first two nights, the third overnight closure will not be required.
Signed diversion routes will be in place during the closures and access for emergency vehicles will be maintained at all times.
Upon completion of the project, road users will benefit from 15km of continuous dual carriageway from Inveralmond roundabout in Perth to Pass of Birnam.
