The bridge consisted of two 136 foot long Pratt type through trusses made of wrought and cast iron and had a total length of 227 feet. It was supported by hand cut, sandstone pier and abutments. The bridge was authorized by J.Y. Templeton, W.H. Dight, D. Carmichael, commissioners of Mercer Co., PA. It was erected in 1888 and in 2014 was removed and disassembled for private use.
