Context paragraphs:
Pennsylvania and Ohio Canal: The Pennsylvania and Ohio Canal, also known as the P & O Canal, the Cross Cut Canal and the Mahoning Canal was a shipping canal which operated from 1840 until 1877 (though the canal was completely abandoned by 1872).  It was unique in that it served to connect canals in two states (the Ohio and Erie Canal in Ohio and the Beaver and Erie Canal in Pennsylvania) and was funded by private interests.

Wabash and Erie Canal: The Wabash and Erie Canal was a shipping canal that linked the Great Lakes to the Ohio River via an artificial waterway.  The canal provided traders with access from the Great Lakes all the way to the Gulf of Mexico.  Over 460 miles long, it was the longest canal ever built in North America.

Low Bridge (song): The popular song "Low Bridge, Everybody Down" was written in 1905 by Thomas S. Allen after Erie Canal barge traffic was converted from mule power to engine power, raising the speed of traffic.  Also known as "Fifteen Years on the Erie Canal", "Fifteen Miles on the Erie Canal", "Erie Canal Song", and "Mule Named Sal", the song memorializes the years from 1825 to 1880 when the mule barges made boomtowns out of Utica, Rome, Syracuse, Rochester, and Buffalo, and transformed New York into the Empire State.  The tune is sadly nostalgic.

The district includes two contributing buildings (the Erie House and the blacksmith shop / mule barn); three contributing engineering structures (Erie Canal Lock 52, culvert, and canal prism of the enlarged Erie Canal); and archaeological sites associated with the canal operations.  Lock 52 was constructed 1849-1853 as part of the Enlarged Erie Canal program.  It remained in operation until the rerouting of the canal under the New York State Barge Canal System in 1917.  The Erie House was built in 1894 and is a two story frame structure that housed a saloon and hotel.

Chenango Canal: The Chenango Canal was a towpath canal built and operated in the mid-19th century in Upstate New York in the United States.  It was 97 miles long and for much of its course followed the Chenango River, along Rt. 12 N-S from Binghamton on the south end to Utica on the north end.  It operated from 1834 to 1878 and provided a significant link in the water transportation system of the northeastern U.S., connecting the Susquehanna River to the Erie Canal.

Schoharie Crossing State Historic Site: Schoharie Crossing State Historic Site, also known as Erie Canal National Historic Landmark, is a historic district that includes the ruins of the Erie Canal aqueduct over Schoharie Creek, and a 3.5 mi long part of the Erie Canal, in the towns of Glen and Florida within Montgomery County, New York.  It was the first part of the old canal to be designated a National Historic Landmark, prior to the designation of the entire New York State Barge Canal as a NHL in 2017.

Indiana Central Canal: The Indiana Central Canal was a canal intended to connect the Wabash and Erie Canal to the Ohio River.  It was funded by the Mammoth Internal Improvement Act, Indiana's attempt to take part in the canal-building craze, started by the Erie Canal.  $3.5 million was allocated for the project, the largest piece of the entire $10 million Act.  However, due to the Panic of 1837, Indiana suffered financial difficulties and had to turn over the canal to the state's creditors, and building of the canal was stopped in 1839.  The canal was supposed to extend 296 mi , from Peru, Indiana, to Evansville, Indiana, where it would reach the Ohio River.  It was originally divided into two sections, North and South.  Later, a third section was designated, called the Indianapolis section.  Only eight miles were completed, with eighty additional miles between Anderson, Indiana, and Martinsville, Indiana, having been partially built.

Fort Wayne Rivergreenway: The Rivergreenway is the backbone of burgeoning Fort Wayne Trails network in Fort Wayne, Indiana and the surrounding area.  The Rivergreenway consists of nearly 25-miles of connected trails following alongside or near the City's three rivers: St. Joseph River, St. Marys River, and Maumee River.  In 2009, the Rivergreenway was designated as a National Recreation Trail.  The trail network also connects to the Wabash & Erie Canal Towpath Trail.  In 2011, the Wabash & Erie Canal Towpath Trail was completed, the Greater Fort Wayne has 50 miles of connected trails.
