This is a unique concrete arch bridge. It has a skew, which is uncommon. But its abutments are the most unusual feature. It is built right into the natural rock outcroppings in the area. Because it is built around the rocks, and the uneven properties of natural rock formations, it does not have equal spring lines. Each end and indeed each side of the bridge has a different spring line. This can be clearly seen in the above photo on this page.
Information and Findings From Pennsylvania's Historic Bridge Inventory
Discussion of Bridge
The skewed, single span, 70'-long reinforced concrete deck arch bridge is finished with concrete parapets that are plain on the roadway face and have panels on the fascia. The spandrel walls are plain. The bridge crosses the abandoned (tracks removed and now overgrown) right of way of the Mill Creek Railroad that was built starting in 1829 between Port Carbon and St. Clair and later beyond to access the coal mines. It was one of the many branch lines that crisscrossed the region, and it became part of the Reading system. The road it carries appears to have been developed as a modern route between Pottsville and Port Carbon. It is not a 19th century road. The bridge is a later example of its technology that was common by 1910. Neither the bridge nor its contexts are historically or technologically significant.
Discussion of Surrounding Area
The bridge carries a 2 lane road over an abandoned railroad right of way of the former Reading Railroad in a sparsely developed, forested setting on the south side of Port Carbon. The overgrown right of way (trackage removed) marks the limit of development in the town. It was the Mill Creek Railroad that went from Port Carbon to St. Clair, and it was part of the Reading system.
