Duquesne Underpass

The trail crosses, via two flyover bridges, busy railroad tracks hauling coal, freight and manufactured goods. The two bridges are connected by trail built on a former U. S. Steel coke gas pipeline. Across the river the Edgar Thomson Works, the last steel plant in the valley, and Braddock Lock and Dam are clearly visible from the trail.
