Vital measures to improve safety are to be made to the only vehicle route into picturesque Glen Lyon.
Described as Scotland’s “longest, loneliest and loveliest glen” it stretches for more than 30 miles and is home to fewer than 100 residents having once had a population of more than 2,000.
It is, however, hugely popular with visitors keen to enjoy some of the finest scenery Highland Perthshire has to offer.
Investigations of the road into the glen have, however, discovered that an important stretch is beginning to degrade and is in need of replacing.
Works will now be carried out during a series of overnight closures in a bid to minimise disruption to the community, while traffic signals will also be installed to allow daytime working.
Work will begin on the Chesthill culvert in Glen Lyon on Monday.
The culvert carries a minor single carriageway road up the glen and over the Allt Linntich Burn, but will now be replaced by a new steel modular bridge.
Perth and Kinross Council said the works were required to “ensure public safety and secure this important section of the only vehicle route up Glen Lyon” after the existing structure was found to show signs of significant wear and tear.
The nature of the new structure means that it can be installed quickly and with minimal disruption. New masonry walls will be constructed on the approaches to the bridge to match the existing adjacent boundary walls.
Most of the works will be carried out between August 19 and September 27, from 9pm to 7am. It is estimated that a maximum of six night closures will be required during this time.
A signed diversion route will be in place during the night time diversions only, using the A827 (along the north side of Loch Tay) and the road between Loch Tay and Glen Lyon, through Gleann Da-Eig, over the west flank of Ben Lawers.
A temporary crossing that can be put in place quickly over excavations for emergency services, if required, will be provided.
