Horseshoe Curve

The Horseshoe Curve extends 2,375 feet in length with a 1,300-foot diameter, crossing two ravines formed by Kittanning Run and Glenwhite Run.

Completed in 1854 by the Pennsylvania Railroad, this engineering structure replaced the Allegheny Portage Railroad as the primary route across the mountains.

The construction involved numerous Irish immigrants who worked for three years using advanced techniques to overcome the mountainous terrain challenges.

Visitors access the observation area through a funicular or stairway, with the Railroaders Memorial Museum managing the on-site visitor center.

During World War II, the military protected this critical transportation point, which facilitated the movement of troops and supplies across the nation.
