Part of the B847 will close overnight in January and February while Network Rail repairs the viaduct that goes over it.

The Garry Viaduct in Perth and Kinross carries the Highland Main Line over the River Garry in the Cairngorms National Park, between Calvine and Struan near Blair Atholl.

Network Rail is carrying out masonry repairs to secure the future of the 161-year-old structure.

The work began in early December last year and Network Rail expects to complete it on Friday 25 April this year.

Network Rail’s engineers will be working on the viaduct above the B847 during the night. Because of this the road will close between 22:00 and 06:00 Saturday to Thursday.

Closures will begin on Saturday 11 January and continue until the morning of Friday 28 February 2025. Road traffic will be diverted, mainly via Tummel Bridge.

The work on the viaduct is part of a wider programme of work by Network Rail in Scotland, which aims to improve performance and ensure safe and reliable rail travel for passengers and freight customers.

Other work on the Highland Main Line this year includes replacing the Rannoch Road bridge at Killiecrankie.

Network Rail is spending £3 million to install a new bridge to replace the 140-year-old bridge over the railway which was recently demolished. The new bridge is now in position, and Network Rail expects to complete the work in March 2025.

Also in the Scottish Highlands, Network Rail is carrying out a £3.5m project to overhaul and refurbish a viaduct between Crianlarich and Oban. The viaduct crosses the River Awe a few miles south of Taynuilt.

“The work at Garry Viaduct is essential so we can maintain the structure and keep services on the Highland Main Line safe and reliable.

“We understand the impact this work is having on those living near Garry Viaduct and we thank the community for their patience whilst we carry out this vital project.”
