From this morning (July 12), traffic management from Transport Scotland will reduce the number of lanes on the dual carriageway.
Between Luncarty and the Pass of Birnam the carriageway will be reduced to one lane for five days from 8am this morning.
A spokesperson for Transport Scotland said: “Road users are advised to allow additional time for their journey and take care on approach to the new traffic management layout.”
Temporary traffic lights will also be operating from the Hunters Lodge underbridge for twenty-four hours a day to build a footpath and other finish works from today (July 12).
These lights are starting at 7:30 and running until 18:00 to help guide traffic safely through the road works.
A spokesperson added: “Pedestrian access at Hunter’s Lodge underpass will be maintained, however, due to the nature of the works, you may be required to wait for a short time before being escorted through the site by our project team.”
Transport Scotland are asking that drivers keep this in mind and allow for extra journey times while the works are in progress.
