query: How long is the Erie Canal?
passage: Erie Canal
The Erie Canal is a canal in New York, United States that is part of the east–west, cross-state route of the New York State Canal System (formerly known as the New York State Barge Canal). Originally, it ran 363 miles (584km) from where Albany meets the Hudson River to where Buffalo meets Lake Erie. It was built to create a navigable water route from New York City and the Atlantic Ocean to the Great Lakes. When completed in 1825, it was the second longest canal in the world (after the Grand Canal in China) and greatly affected the development and economy of New York, New York City, and the United States.[2]
passage: Erie Canal
The Erie made use of the favorable conditions of New York's unique topography, which provided that area with the only break in the Appalachians south of the Saint Lawrence River. The Hudson is tidal to Troy, and Albany is west of the Appalachians. It allowed for east–west navigation from the coast to the Great Lakes within USterritory.[24] The canal system thus gave New York a competitive advantage, helped New York City develop as an international trade center, and allowed Buffalo to grow from just 200settlers in 1820 to more than 18,000 people by 1840. The port of New York became essentially the Atlantic home port for all of the Midwest—because of this vital connection and others to follow, such as the railroads, New York would become known as the "Empire State" or "the great Empire State".[3]
