St Fillans, Allt An Fhionn, former Railway Viaduct

Comments :

It is a good example of early 20th century concrete engineering and of historical importance, related to the introduction of the railway to Loch Earn. It is one of a series of three such viaducts/bridges in St Fillans (see separate list descriptions). 5-span viaduct over Allt-An-Fhionn Burn, c 80m long. Curved in plan. Channeled mass concrete, with 5 segmental arches. The parapet is defined by a string course and a projecting cope. Above each pier is a shallow refuge in the S parapet. Materials: Concrete, cast iron rainwater goods. The line closed fully in 1951. [HS] The width between parapets is 5,0 m.
