Killiecrankie renewal
A £3m investment to renew Rannoch Road bridge in Killiecrankie.
Network Rail is delivering a £3m investment to replace Rannoch Road bridge in Killiecrankie.
This project is part of a wide-ranging bridge modernisation programme aimed at protecting and improving Scotland’s Railway, with over £1.95 billion being invested to increase reliability and improve performance.
Along with principal contractor AmcoGiffen, engineers will deliver a six-month programme of works to renew a 128-year-old bridge over the Highland Main Line.
To minimise the impact of our work, a temporary road bridge will be in place adjacent off the B8079, adjacent to the existing structure, to allow all-vehicle access to be maintained throughout, except during two weekends of extended engineering works taking place the last weekend in November and first weekend in December.
Project Timeline
-
Sept 2024 - Compound set-up includes installation of temporary offices and welfare facilities for staff, delivery of plant, materials and equipment to site.
-
Oct 2024 to March 2025 - Work begins to replace the bridge deck.
-
Nov 2024 - Extended period of engineering works to demolish the existing bridge.
-
Dec 2024 - Extended period of engineering works to install the new bridge.
-
March 2025 - Completion of the works and demobilisation.
Possible Disruptions
-
Temporary Road Closure
Access at Rannoch Road will be maintained throughout the works except when the existing bridge is demolished and the new bridge is installed.
This will be done over two consecutive weekends of extended engineering works, with no trains running on the line, from 30 November to 2 December and 7 December to 9 December.
Over both weekends, the road will be closed at the bridge, with traffic management measures in place including an all-vehicle diversion route.

What's happening?
Old Bridge Deck Removed
Over the last weekend in November, the project achieved a significant milestone with the removal of the old bridge deck.
During a period of continuous working, when no trains were running on the line, engineers lifted out the single steel span.
Over the first weekend in December, the new bridge deck will be craned into position. During this time, the temporary road bridge will be closed to allow the team on site to safely deliver this part of the works.
Temporary Road Bridge Opens
The temporary bridge next to the existing bridge on Rannoch Road opened on 4 November. This will allow all-vehicle access to be maintained during the works, except during removal of the old bridge deck and installation of the new one.
Why?
The work is designed to protect and extend the lifespan of the bridge.
It's part of a wider, rolling programme of maintenance aimed at keeping the network safe and reliable.
What will change?
Our engineers are removing the existing bridge deck and replacing this to extend the lifespan of the stucutre over the Highland Main Line.
