Bridges & Viaducts

Have you ever wondered when a bridge becomes a viaduct? Of the following five structures, there can be little argument that the one furthest left is a bridge whilst far-right stands a viaduct. What would you define the three in the middle as?

Here are three suggestions from visitors to Forgotten Relics.

The first looks upon a viaduct as being a structure with one or more intermediate supports, unless there’s a local convention such as on the Thames where crossings are always known as bridges. In a similar vein, the second – an experienced railway bridge examiner – generally regards a viaduct as having five or more spans. The third considers a bridge to be any structure which either crosses a river or only has one span. A viaduct is used to take a railway over a valley.
