Old Croton Aqueduct, Harlem River Crossing, Spanning Harlem River, Bronx, Bronx County, NY

Significance: The Old Croton Aqueduct was New York City's first municipal water supply project, and is an outstanding example of early 19th century civil engineering. High Bridge best exemplifies this. Upon completion High Bridge was 1420 feet long and 136 feet high (from the bottom of the river). Sixteen piers created fifteen arched openings of which eight were 80 feet wide and seven were 50 feet in width. Its remaining portion is the most readily visible section of the Croton Aqueduct standing today.
