View The Original Patent For The Lenticular Truss

This bridge was relocated here and preserved for pedestrian use in Lazy Brook Park. Please also see HistoricBridges.org's page for photos and documentation of the bridge in its previous location on SR-1029.

This eight panel structure was built by the Corrugated Metal Company, which later became the Berlin Iron Bridge Company. These companies are known for bridges such as the Pierceville Bridge, a patented type of truss known today as the lenticular truss. These bridges feature a beautiful and distinctive shape to them that is unique enough that they can be considered among the rarest types of bridges remaining in the country. The preservation of each surviving lenticular truss bridge is absolutely essential. Having been built by the Corrugated Metal Company, this is among the earliest examples of a lenticular through truss. It is also remarkably complete, with very few alterations. This is also one of the only bridges where the Historic Bridge Inventory itself strongly advocates for the preservation of the bridge. Be sure to review the HAER page for this bridge as it contains drawings and data pages that provide an informative historical narrative for this structure.

In June, 2015, a project to relocate and restore this historic bridge to nearby Lazy Brook Park for non-motorized traffic began. As of summer 2018 the project is complete and the bridge is open.

The preservation of the Pierceville Bridge is truly a historic moment for Pennsylvania. The Pierceville Bridge preservation project was an in-kind restoration of the bridge, the first of its kind in Pennsylvania. It is also believed to be the first PennDOT contract in decades to include riveting as part of the contract, and certainly the first PennDOT project to specify riveting for preservation work. Pennsylvania joins a growing number of states that understand the importance and feasibility of in-kind restoration and use of riveting in preservation work. Rivets were replaced with rivets rather than bolts. Any bridge parts that were beyond repair were replaced with replicas. In particular the edge bracing which had been damaged by floods, was replicated, as were the deteriorated end posts.

The general contractor for this project was Kriger Construction. The disassembly, restoration, and reassembly of the lenticular truss bridge was subcontracted to Bach Steel. McCormick Taylor was the engineer for the project.
