Headfield Viaduct is a disused railway viaduct in Dewsbury, West Yorkshire, England. It was built in 1887 to carry the Great Northern Railway's Headfield branch line over the River Calder and the surrounding valley. The viaduct is 1,028 feet (313 m) long and consists of 14 masonry arches, one span of plate girders, and two bowstring spans over the river.

The viaduct was designed by Henry Fraser and his brother-in-law William Beswick-Myers. Beswick-Myers was a pioneer in the use of steel in bridge construction, and the Headfield Viaduct is one of his most notable works. The viaduct is made of red brick, with sandstone facings on the piers and arches. The bowstring spans are particularly impressive, with their long, slender trusses.

The Headfield Viaduct was an important piece of engineering infrastructure in its day. It allowed the Great Northern Railway to connect its line from Ossett to Dewsbury with the Lancashire & Yorkshire Railway's line from Wakefield to Halifax. This gave the GNR access to the important Spen Valley industrial region.

The viaduct closed to passenger traffic in 1964 and to goods traffic in 1971. It has since been restored and is now a popular spot for walkers and cyclists. The viaduct is also a popular filming location, and has appeared in several TV shows and films, including The Railway Children (1970) and Peaky Blinders (2013-present).

Here are some interesting facts about Headfield Viaduct:

• The viaduct is the longest brick viaduct in Yorkshire.
• The bowstring spans over the river are the only ones of their type in the UK.
• The viaduct was built by local contractors Messrs Brier, Son & Wilson.
• The viaduct cost £14,000 to build (equivalent to around £1.5 million today).
• The viaduct was closed to traffic in 1971 and was restored in the 1990s.
• The viaduct is now a Grade II listed building.

Headfield Viaduct is a remarkable piece of Victorian engineering and architecture. It is a testament to the skills and craftsmanship of the people who built it. The viaduct is also a reminder of the important role that railways played in the development of industrial Britain.
