Knaresborough Viaduct

Knaresborough Viaduct carries the Harrogate line over the River Nidd in Knaresborough, North Yorkshire, England. The railway line was supposed to have opened in 1848, but the first unfinished viaduct collapsed into the river and its replacement delayed the opening of the line through the town by three years.

The viaduct spans the Nidd Gorge about 200 metres north of the ruins of Knaresborough Castle and is a well-known landmark in the town.
