Avon Viaduct, Linlithgow

The Avon Viaduct carries the railway over the River Avon at Linlithgow, West Lothian, Scotland.

The 442 yd, 23-arch bridge was built in 1839–1841 by John Miller, engineer for the Edinburgh and Glasgow Railway.

The viaduct straddles the border between the West Lothian and Falkirk Council areas, so has two Historic Environment Scotland listings. The viaduct is a category A listed building.

There is another Avon Viaduct located 4 mi south-west of Linlithgow; this Category B listed structure was built c. 1850 for the Monkland Railways and is now disused. To distinguish it from the older viaduct it is usually referred to by the alternative name of Westfield Viaduct.

These two viaducts are further not to be confused with the nearby Avonbank Viaduct located 1.2 mi downstream and to the north-west. The Avonbank Viaduct was opened by the Slamannan and Borrowstounness Railway in 1847 and now carries the Bo'ness and Kinneil Railway over the river.
