Focus Project

  • Northwest view of the Turnpike I-76 Beaver River crossing.
    United States Beaver River Bridge, Beaver County, PA
    Travelers who regularly cross the Beaver River Bridge along the Pennsylvania Turnpike (I-76) in Beaver County, Pennsylvania, are accustomed to heavy congestion and delays, especially during peak hours. The bridge spans the Beaver River along the western corridor of the cross-state highway near the PA/Ohio border and serves as a connecting point for various communities and commercial areas in the region.
