Hello!

The Erie Canala is a waterway that was built from Bufalo to Albany. In this way, the channel links the agricultural territories located in the Midwest with the Atlantic Ocean. The objective of this work was to accelerate the transport of people and cargo, thus promoting commercial exchange.

Its construction began in 1817 and ended in 1825, when it was inaugurated.
