1845 : Lockwood Viaduct, Huddersfield - The Huddersfield and Sheffield Junction Railway required the design of a viaduct at Lockwood and turned to John Hawkshaw. It is one of the longest viaducts in the country and probably the finest in the West Riding of Yorkshire. It is 476 yards long, 120 feet high at its highest and has 34 semicircular arches of 30 feet span with two larger ones of 42 and 70 feet. It contains nearly one million cubic feet of masonry.
