·         Project to take up to four weeks to complete

·         A9 to remain open with traffic in single lanes for safety

A new £600,000 project is underway to replace the expansion joints on the Killiecrankie Viaduct on the A9 between Pitlochry and Blair Atholl that is expected to take up to four weeks to complete.

The expansion joints on the 650m long viaduct are essential to allow the structure to expand and contract as the temperature changes.  The existing joints require replacement to ensure the continued safe use of the viaduct and the smooth passage of vehicles over the joints.  The viaduct is split into four sections and each one moves by up to 10cm between summer and winter temperatures.

To allow the joints to be installed safely and to keep traffic moving on the A9 the project will be carried out using a contraflow system with a single lane of traffic available for northbound and southbound traffic at all times.  Recovery vehicles will also be on site 24 hours a day to help keep traffic moving and ensure any disruption is minimised. 

Commenting on the project, Eddie Ross, BEAR Scotland’s North West Representative said: “This £600,000 project is vital to ensuring the A9 Killiecrankie Viaduct remains a safe, reliable structure for road users of the A9.  Our teams have designed the project to include contraflow traffic management, ensuring the A9 trunk road remains open throughout this project and disruption is minimised as much as possible.

“Our teams will do all they can to complete the joint replacements as quickly and safely as they can.  We encourage all road users to take account of information shown on temporary traffic signs to ensure their own safety and that of our teams and remind them to plan ahead by checking the Traffic Scotland website and leave some extra time before they travel.” 

This bridge joint replacement scheme is part of a network wide programme of bridge joint replacements including another six structures on the A9 and one on the A87 trunk road.  The total value of all these works is approximately £860,000.
