Interpreting the Evidence
Erie Canal Locks and Towpath at Lockport, 1895
Suggested Teaching Instructions
Erie Canal locks and towpath, Lockport, New York, 1895.
A lock is a water-filled chamber with huge gates or doors at both ends. Locks were usually built in a series up the sides of a hill or mountain. The construction of the original five-step locks in Lockport presented a major engineering challenge. The canal had to rise up a cliff of solid rock that was sixty-six feet high. The locks were blasted out of the cliff by the canal workers. The double set of five combined locks was the design of Nathan S. Roberts. One set of locks was for ascending traffic that was headed west, and the other set was for descending traffic heading east. The town that grew up around this set of locks became known as Lockport.
