Network Rail has awarded AmcoGiffen a 拢3.4m contract to carry out repairs to the Glenfinnan viaduct in the Scottish Highlands.
Glenfinnan viaduct sits 30 metres above the River Finnan on the West Highland Line, 17 miles from Fort William. It is built from mass concrete and has 21 semicircular spans of 15 metres. At 380 metres, it is the longest concrete railway bridge in Scotland.
The maintenance works are expected to take just under 12 months to complete and will see rope-access engineers assessing the condition and strength of the viaduct and making improvements beneath the track to keep the stone ballast in place.
Network Rail project manager Laura Craig said: 鈥淭he main works to the viaduct will be concrete repairs. We鈥檒l also be doing some repairs to the pier that sits in the River Finnan. Years of planning have gone into this project.
鈥淭he work will not have a massive visual impact on the way the viaduct looks and that鈥檚 very deliberate, with it being grade A listed. We won鈥檛 be scaffolding the structure at all but in the coming weeks, you鈥檒l start to see the rope access technicians on the viaduct as they begin work.鈥�
The viaduct was built by Robert McAlpine & Sons of Glasgow, as the company was then called, and designed by Glasgow consulting engineer Simpson & Wilson. Construction took from July 1897 until October 1898 and cost 拢18,904, which is about 拢3m in today's money.
