Old Champlain Canal Sidecut Locks

Serving as an alternative way to get from the Old Champlain Canal to the Hudson River, the Sidecut Locks are a flight of three combined locks.
The three locks combined raised and lowered boats about thirty feet. This simple sidecut allowed boats to enter the Hudson River without entering the Old Erie Canal, thus reducing travel time and congestion.
The sidecut was replaced by Lock E2, the flight of locks still play an integral part of the canal system as a waste weir (spillway).
