A bridge carrying the former Harrogate to Ripon railway over the Nidd. Today, part of the trackbed, between Bilton and Ripley has reopened as a cycle route.
The Nidd viaduct at Bilton which stands at 104 feet above the river was built in 1848 and was part of the now defunct railway line which used to run to Ripley, Ripon and Thirsk, carrying freight (mainly coal and later gas) and passengers until it closed in 1967.
