Mitchell's Mill Bridge, Spanning Winter's Run on Carrs Mill Road, west of Bel Air, Bel Air, Harford County, MD

Significance: The Mitchell's Mill Bridge is a surviving example of the late 19th century wrought iron bridges once found throughout rural Maryland. The Pratt pony truss employed in the Mitchell's Mill span was widely used in the design of single-span bridges erected between 1870 and 1935. Due to increasing development in the rural areas of Maryland and the accompanying replacement of older highway bridges, relatively few of the 19th century Pratt truss bridges remain in northern Maryland.
