Monongahela River and
Pittsburgh & Lake Erie Railroad
Overview
Examination of aerial maps reveals this section is industrial. Surprisingly, much of the industry is hidden from the trail, which is more scenic than might be expected. Often vegetation encloses the sides and top view.

It follows the walkway next to the Monongahela River to the trail’s terminus in the park at mile marker 148+.
