Elizabeth, PA

Elizabeth occupies the east bank of the Monongahela River where Pennsylvania Route 51 reaches the water in southern Allegheny County. The borough began as Elizabeth Town in 1787, founded by Samuel Mackay, Colonel Stephen Bayard, and Elizabeth Mackay Bayard, and it became one of Allegheny County's first townships the next year. Glassmaking, the manufacture of secure storage boxes, and steamboat and ship building followed, with O'Neil & Company and the Elizabeth Marine Ways giving the waterfront a working-industrial past.

The river still sets the borough's orientation. Elizabeth Forward School District serves the community, and the borough's municipal authority, police, fire, and emergency services operate alongside the roads connecting it to the Mon Valley and Pittsburgh's southern region. Walker Heights and Town Hill add recognizable neighborhood names above the river corridor. The marine ways operated through 1925, yet the shoreline remains the useful reference point for understanding Elizabeth: homes and civic services sit beside a Route 51 crossing in a town whose history was made by moving glass, boats, and people along the Monongahela.
