The Erie Canal was inaugurated on October 26, 1825 and connects Albany along the Hudson River with Buffalo, located on the Niagara River in the state of New York.

This connection was first proposed as early as 1699 but its construction began in 1817. About 584 km long, it has a total of 36 locks and a total height difference of 172 meters.
