Antietam Aqueduct

The C&O Canal aqueducts are “water bridges” that carried canal boats over the creeks and rivers that flowed into the Potomac River. Built in 1834, the Antietam Aqueduct is the fifth of twelve such “works of art” on the canal. The 140-foot long structure has three elliptical arches and was made with limestone from a nearby quarry. It’s located near Antietam Battlefield and was damaged by the Confederates during General Jubal Early’s invasion of Maryland in 1864.
