Ribblehead Viaduct is on the Settle-Carlisle Railway and is one of the most picturesque stretches of railway in the country. It is listed Grade II* which makes it pretty special. 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 and needed 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 – Carlisle line was the last main railway in Britain to be constructed primarily with manual labour. If you fancy a visit, find out more here.
