Cabin John Aqueduct Bridge
Historic Bridge
Designed and built by the U.S. Army Corps of Engineers in 1864, the Cabin John Aqueduct Bridge carries both water and vehicles across Cabin John Creek. It was originally known as the Union Arch Bridge and built under the direction of Lt. Montgomery C. Meigs, who also supervised the construction of the U.S. Capitol.
Built of sandstone and granite, the bridge spans 220 feet over the Cabin John Creek. When it was built, it was the longest single-span masonry arch in the world.
