EHG5433 - Walkover and condition survey - Beauly to Denny 400kV Overhead Transmission Line, G Wade's Military Road, Culachy to Melgarve

A rapid archaeological condition survey was undertaken by Northlight Heritage between the 21st and the 23rd September 2016 on General Wade's Military Road (Scheduled Monument No's. 6140, 6141, 6142, 6128 & 6129) as part of the Beauly to Denny 400kV overhead line development programme. The survey focused on the scheduled stretch of the 18th century military road which runs from a point some 3km to the south of Fort Augustus, across the summit of the Corrieyairack Pass, down to Melgarve in the east, a distance of approximately 17.5km. This survey served as a final update to previous condition surveys undertaken on the route of the military road as part of both construction of the new 400kv overhead line and dismantling of the old 132kV overhead line. It also allowed assessment of whether recommended repairs and remedial work had been sufficiently carried out. Overall the route of the military road was in relatively good condition. It had been subject to varying degrees of maintenance in recent times resulting in a much improved drainage system and road surface. <1>
