Pennsylvania Main Line Canal, Juniata Division, Canal Section

Why it's listed
Located southwest of Lewistown in Mifflin County, this 8,420-foot stretch of the Juniata Division canal was completed in 1830 as part of the Pennsylvania Main Line Canal, which linked Philadelphia and Pittsburgh. The canal carried heavy freight such as iron and coal to urban markets at far lower cost than road haulage, and the Juniata valley's iron industry depended on it. The Pennsylvania Railroad bought the canal in 1857, and this section operated until the flood of 1889. Its two sets of original stone bridge abutments and the canal prism, towpath and clay liner survive from the original construction. Restoration by a private partnership began in 1970 and was completed in 1986, and the reach is the longest restored and rewatered part of the entire system. Its significance lies in transportation history and in its engineering, notably the surviving abutments and the canal's form.
Significance in brief: The nomination argues that this section was part of the uninterrupted transportation route between Philadelphia and Pittsburgh and that it is the only restored and rewatered part of the 127.5-mile Juniata Division. It also cites the canal's role in carrying bulky freight, including iron and coal, and its contribution to the regional iron industry. Its engineering and the surviving original abutments and canal form are presented as the basis for its significance.
