Thunder Bridge

Love these Scott, thanks for sharing.

I have no doubt that the bridge was fabricated by Pan American Bridge Company out of New Castle as that is their plaque design. It was nearly identical to the Indiana Bridge Company plaque except Pan Am used the little symbol between the commissioner names and the contractor/fabricator name. I've always had a theory that a man named Eugene Runyan designed the plaques because he worked for IBCo and then left for Pan Am after it was formed in 1902. Mr. Hoffman, the contractor, used Pan Am to fabricate other bridge superstructures for him as well.

My coworker at the highway dept. Earl Snyder saved the two plaques from this bridge then I watched over them for many years ! The county still has them but hopefully Iíll get them displayed at the museum someday !

This bridge is identified as B-99 in the county bridge inventory and was locally referred to as "Thunder Bridge" due to the wood plank deck "thundering" as vehicles crossed the structure.
