According to Canmore, Scotland's national record of the historic environment online, the viaduct was designed by the important Scottish engineer Joseph Mitchell (1803-1883) to carry the Aberfeldy branch of the Inverness and Perth Junction Railway across the River Tay:
It is of lattice girder type on cast iron piers and measures 420 ft (128m) in overall length and 49 ft (14.9m) in height; it comprises two spans of 137 ft (41.8m) and another two of 41 ft 6 ins (12.7m). The cylindrical piers measure 8 ft (2.4m) in diameter and are weighed down with masonry rubble filled with Portland cement, the additional side spans being added as a protection against damage from floodwater.
The viaduct, which cost £13,772 to build, was opened on 9 September 1863. It is still used, although now only for "private road traffic" (Canmore).
The viaduct is Category A listed, bearing testimony to Mitchell's skill in managing the challenging terrain of these regions, and his "precautions that his viaducts and bridges should be built on secure foundations, and that the masonry and all other works under his charge should be thoroughly well executed" (qtd. in "Joseph Mitchell," from his obituary in the Proceedings of the Institution of Civil Engineers of 1884).
