Location

The Creag-an-Arnain Viaduct is a railway viaduct that carries the West Highland Line.

History

The viaduct opened to traffic in 1894 as part of the West Highland Line between Glasgow and Fort William.^[1] It may have been designed by James Miller.^[2]

Design

The viaduct has eight arches of 11 metres (36 ft) span, for a total length of 104 metres (341 ft).^[1] It has a slight curve, and crosses two unnamed burns on the western shore of Loch Lomond.^[1]

It is the only conventional masonry viaduct on the West Highland line, many others being made of concrete.^[3] It was built of stone arches instead of lattice girders, as many railway bridges were at the time, to avoid contemporary criticism.^[1]
