Yarm Viaduct

Yarm Viaduct was built by the Leeds Northern Railway to extend the Leeds & Thirsk Railway Line from Northallerton to Stockton-on-Tees. It was designed by Thomas Grainger and John Bourne, engineers from Edinburgh. Construction began in 1848 and lasted just over four years, at a cost of £44,500.

It became a remarkable feat of engineering; all the building materials had to hauled into position by teams of horses, and a pulley system as there were no mechanical cranes or excavators at that time. The viaduct is half a mile, or almost 695 metres, long and approximately 7 million bricks were used to build it. It has 43 arches, two of which span the River Tees, and are 65 feet high. The viaduct was officially opened on 15th May 1852.
