New York State Barge Canal, Lockport Locks, Richmond Avenue, Lockport, Niagara County, NY

Locks E34 and E35 were surveyed as part of the 2009 New York State Barge Canal survey; see HAER Nos. NY-515 (Lock E34) and NY-516 (Lock E35).
Significance: Locks 67-71 (north flight) comprise a rare 19th-century example of multiple locks directly connected into a flight and an in-situ example of once-common cut-stone lock construction. This flight is the most complete surviving artifact from the enlarged Erie Canal, the second version of the first major transportation artery between the East Coast and the Great Lakes. Locks 34 and 35 form an excellent example of early 20th-century concrete, electrically powered lock design, and they pioneered methods also used on the Panama Canal. The site is unique in having these two designs together.
