This handsome three-arch bridge over Antietam Creek was constructed by John Weaver in 1839 and was specially adapted to the grain mill built at the same time. The westernmost of the three arches was designed to accommodate the millrace flue, and the floor of the bridge at its southwest corner was widened to permit loading and unloading of wagons directly under the second-floor-level mill door. The arch spans are 23 feet, 26 feet, and 23 feet, with a total bridge length of 132 feet.
