Question: What was longer, the Black River Canal or the Chenango Canal?

full_context: Document 1: Junction Canal: The Junction Canal was a canal in the states of New York and Pennsylvania in the United States.

The canal was partly open in 1854, but the entire length was not finished until 1858. The completed canal was 18 mi long and had 11 locks. Then intent was to lengthen the reach of the Chemung Canal deeper into Pennsylvania in order to connect to the canal systems there. Competition with railroads led to diminished use of the canal. In 1865 the canal was severely damaged by a flood. In 1866, the stock company was authorized to change its name to the "Junction Canal and Railroad Company," and work commenced in constructing a railroad on its right of way.

Document 7: Pennsylvania Canal (Susquehanna Division): The Susquehanna Canal of the Pennsylvania Canal System was funded and authorized as part of the 1826 Main Line of Public Works enabling act, and would later become the Susquehanna Division of the Pennsylvania Canal under the Pennsylvania Canal Commission. Constructed early on in America's brief canal age, it formed an integral segment of the water focused transportation system which cut Philadelphia-Pittsburgh (pre-railroad) travel time from nearly a month to just four days. One of the system's navigations, the Susquehanna Canal/division created a mule-towed navigable channel 41 mi along the west bank of the main stem of the Susquehanna River between a lock terminus near the mouth of the Juniata Tributary River and the canal basin at Northumberland. Meeting the West Branch Canal and the North Branch Canal at Northumberland, it formed a link between the public and private canals upriver and the main east–west Pennsylvania Canal route known as the Main Line of Public Works which was devised to connect Philadelphia to Pittsburgh, southern New York, northern Pennsylvania and Lake Erie using most of the far reaches of the Susquehanna's tributaries.
