Charleroi-Monessen Bridge, Spanning Monongahela River at State Route 2018, North Charleroi, Washington County, PA

Significance: It is significant as a rare surviving example of a long, multiple-span metal truss bridge. Built as a toll bridge to carry vehicular, pedestrian, and trolley traffic across the Monongahela River, the bridge improved regional transportation and contributed toward the economic development of Monongahela River valley towns. Construction of a bridge across the Monongahela River at North Charleroi surmounted a formidable natural barrier and completed a regional street railroad transportation network that stretched from urban Pittsburgh to developing Westmoreland County.
