Springing Over the Monocacy
The Enduring Aqueduct
Building the Monocacy Aqueduct required four years, 200 men, and thousands of tons of cut stone. Benjamin Wright, the canal’s Chief Engineer, designed the aqueduct and oversaw its construction.
Dissatisfied with the early work on the 516-foot aqueduct, he had the first three piers torn down and rebuilt with better stone. By 1833 it was completed.
As originally designed, it would have been very ornamental. Wright’s specifications called for a careful use of white and red stone to create a beautiful yet functional structure. Although the red stone was not used, the beauty, economy, and durability of the Monocacy Aqueduct remain.
Aqueduct No. 2, over the Monocacy River, is a very splendid work, built of a superior granite stone, resembling white marble. Seventh

The Enduring Aqueduct. From 1833 until 1924 this aqueduct carried the C&O Canal over the Monocacy River. Thousands of boats, boatmen and mules, and millions of tons of coal and other cargo passed over this aqueduct. If you look closely you can see signs of their passage in wear marks on the stones and the iron rail posts.
The aqueduct endured despite nature's fury and man's best efforts. Floods roaring down the Monocacy washed ons of debris against the side of the aqueduct. Confederate troops tried twice to blow up the structure, failing both times.
Floods and changing technology eventually put an end to the C & O Canal Company and with it the boatman’s life. No longer part of an active transportation route, the Monocacy Aqueduct endures as a link to the past and a monument to the ambitions and hopes of those who built and worked on the C&O Canal.

Preservation through Partnerships. Time, hard use, and the rivers all took their toll on the Monocacy Aqueduct. Its elegant appearance had been masked by steel braces installed to stabilize it after the 1972 Hurricana Agnes flood. Major floods and annual freshets continued to pummel the structure with debris. By 1994, seventy years after the canal had shut down, it appeared that floods and neglect would be the ruination of the stately structure.
Fortunately, an impressive coalition was formed to save the old aqueduct. First led by the C&O Canal Association and later joined by the American Society of Civil Engineers and the National Trust for Historic Preservation, the partnership grew with the support of First Lady Hillary Rodham-Clinton, United States Senators Paul Sarbanes and Barbara Mikulski and United States Representatives Roscoe Bartlett and Connie Morella, as well as state, country and local officials. Working under the leadership of Park Superintendent Douglas Faris, the partnership developed
