The Delaware and Hudson Canal was the first venture of the Delaware and Hudson Canal Company, which would later build the Delaware and Hudson Railway. Between 1828 and 1899, the canal's barges carried anthracite coal from the mines of Northeastern Pennsylvania to the Hudson River and thence to market in New York City. For these reasons, the canal was declared a National Historic Landmark in 1968. The canal was abandoned in the early 20th century, and much of it was subsequently drained and filled. A few fragments remain in New York and Pennsylvania, and are in use as parks and historic sites.
