Ribblehead Viaduct

The Ribblehead Viaduct or Batty Moss Viaduct carries the Settle–Carlisle railway across Batty Moss in the Ribble Valley at Ribblehead, in North Yorkshire, England. The viaduct, built by the Midland Railway, is 28 miles north-west of Skipton and 26 miles south-east of Kendal. It is a Grade II* listed structure. Ribblehead Viaduct is the longest and the third tallest structure on the Settle–Carlisle line.

The viaduct was designed by John Sydney Crossley, chief engineer of the Midland Railway, who was responsible for the design and construction of all major structures along the line. The viaduct was necessitated by the challenging terrain of the route. Construction began in late 1869. It necessitated a large workforce, up to 2,300 men, most of whom lived in shanty towns set up near its base. Over 100 men lost their lives during its construction. The Settle to Carlisle line was the last main railway in Britain to be constructed primarily with manual labour.
