The cotton milling industry started in Maryland in the 18th century and flourished in the 19th century. Cotton was shipped cheaply from Southern ports and hauled overland by mule and oxen teams to the mills before rail transportation served Savage. In 1835 the Washington branch of the B&O Railroad was completed, and Savage Station was established on the line about a mile southeast of the present mill. A spur of the B&O was laid to the Savage factory in 1887, and it was at this time that the famous Bollman Truss Railroad Bridge was moved to its present site from another location. Originally built in 1852, it was one of about 100 on the B&O line. Beloved by railroad buffs, the iron truss bridge is the only one of its type in the world, and, along with the Savage Mill, is on the National Register of Historic Places.
