Drivers on the A9 face weeks of frustration when dual carriageway works begin on the stretch between Luncarty and the Pass of Birnam.
Contractors Balfour Beatty will be working on the route from November 26 until Christmas.
Traffic restrictions around the works will include temporary, two-way traffic lights and a speed restriction of 30mph.
The measures are to allow the construction of temporary site access points between. The main project to dual the stretch of road will begin early next year.
The works will take place overnight – from 7.30pm to 6am the following morning – and will run from Monday to Saturday.
The project will be completed in phases, with teams working from Luncarty northwards. The Balfour Beatty team plan to restrict only a short section of the carriageway at any given time.
A spokesperson for Transport Scotland said any delays would be monitored.
“Road users are being advised to take care on approach to the area and allow additional time for their journey,” he added.
“Over the course of the winter period, Balfour Beatty plans to undertake some preparatory works including the construction of temporary access to works areas in anticipation of the main works which will commence in earnest from early 2019.
“We will work closely with the contractor to minimise any disruption to traffic and would like to thank road users in advance for their patience.”
A spokesperson from Balfour Beatty said: “We apologise for any inconvenience caused during these works. If you have any enquiries regarding these works, we have a dedicated enquiries line which is available 24 hours a day on 0800 193 7313.”
Upon completion of the Luncarty to Pass of Birnam Project, 15km of continuous dual carriageway will run from Inveralmond roundabout in Perth to the Pass of Birnam.
It is anticipated the work will improve the safety of the A9 and provide safer overtaking opportunities along the route. Transport Scotland hope these improvements will reduce driver stress as well as improving journey times and overall operational effectiveness.
Work to upgrade 80 miles of single carriageway between Perth and Inverness is one of Scotland’s largest transport infrastructure programmes.
The £3billion project is scheduled for completion in 2025.
