When the Erie Canal opened in 1825, it was an immediate success, leading to an enlargement completed in 1862. By the early 1900s, another expansion occurred, and renamed the New York State Barge Canal, it took advantage of modern materials and electrical power. Although no remnants of the original canal remain, Lockport preserves the westbound enlarged Flight of Five and Barge Canal locks, making it the only place on the canal where functioning modern locks and historic locks can be seen side-by-side. Between 1910 and 1918, two sets of mechanical gates replaced the manually operated eastbound Flight of Five gates from the 1838-1862 enlargement. The grassy area marks the path of the enlarged eastbound Flight of Five locks that were removed during the early 1900s enlargement. A public art installation reproduces a circa 1897 photograph of the lock tenders, local workers in charge of lock operations. The historic westbound Flight of Five locks are the most complete surviving example from the enlarged canal period, and their current wooden gates reproduce those of 1838-1862. The paved incline was originally a dirt and gravel towpath, where mules and horses pulled packet and barge boats along the canal, while manpower took over as the boats passed through the Flight of Five.
