How many people used the Erie Canal in each year?

The Erie Canal, completed in 1825, saw a gradual increase in traffic over the years. In its early years, it accommodated around 1,000 boats in the first year, with usage growing significantly to over 100,000 boat trips annually by the 1850s. By the late 19th century, the canal was used by approximately 1.5 million people each year. However, specific annual usage figures can vary widely due to factors like economic conditions and improvements in transportation infrastructure.
