Gilpin Township is a Second class Township in Armstrong County, Pennsylvania, United States. It is a township rich in history, dating back to early 19th-century settlement. Officially incorporated on December 26, 1878, it evolved from an agricultural and timber-based economy to an industrial hub, supported by its abundant natural resources—including coal, salt, timber, natural gas, and sand—and its strategic location along the Allegheny and Kiskiminetas Rivers. These rivers not only fostered trade and transportation but also enabled Gilpin’s transformation into a manufacturing center. The township includes various communities—Bagdad, Johnetta, Schenley, Georgetown, Banfield, Forks Church, Aladdin, and Maher Heights—each contributing uniquely to its development and legacy. As of the 2020 Census, its population was 2,411.

The Freeport Rail Bridge is a truss bridge that carries the Norfolk Southern Railway across the Allegheny River between Freeport and Allegheny Township in Pennsylvania.
A structure originally created on this site by the Pennsylvania Railroad as part of their West Penn Line in 1866. In 1895, the railroad replaced this bridge; the third and current incarnation was completed in 1950, along with new approach ramps that eliminated a narrow tunnel.
Prior to 1957, passenger service was carried along this line alongside freight. Following the decline of the PRR, Conrail took over control of the bridge. Currently, it is operated as part of the Pittsburgh Division of Norfolk Southern.
