Enlarged Erie Canal Lock No. 52, built in 1851, is located just northwest of the Village of Port Byron, Town of Mentz, Cayuga County, N.Y. It is a double-chamber lock, with the south chamber double-length on the west (foot) end. Whereas, in general, canal waters flow downhill to the east, due to a rise in the center of the state, Lock 52 locked down to the west, thus the usual three overflow openings are on the east end. The lock had an 11.298 foot descent to the west.
The lock is located on the edge of the New York State Thruway. Because of its accessibility and historical importance, the Thruway Authority has turned the lock and the adjacent buildings (owned by the Canal Society of New York State) into a historical center accessible from both the Thruway and the village of Port Byron.
Note: For another look at the western end of Lock 52, YouTube includes a video of the western end,
morphing from the view in 2007 to the way the lock looked when it was in use.
