Lockwood Viaduct
Designed by noted civil engineer John Hawkshaw for the Huddersfield and Sheffield Junction Railway, which was formed to build a line between Huddersfield and a junction on the existing Sheffield, Ashton-under-Lyne & Manchester Railway near to the station at Penistone.
The contractors were Miller, Blackie and Shortridge.
The master mason was Job Hirst, son of Joshua "Red Jos" Hirst of Kirkheaton, who later built railway viaducts in India.
