Engineering and Design
The bridge is a prime example of a Pratt thru truss design. In this specific engineering style, the bridge's structural framework (the truss) extends above the roadway, meaning traffic passes "through" the structure rather than on top of it. This design was widely adopted for its efficiency in distributing weight and tension.
The construction was carried out by the Wrought Iron Bridge Company, a firm known for producing durable metal bridges during the era of expanding American infrastructure. Today, the bridge has been rehabilitated to preserve its structural integrity while maintaining its historic character, marked by an official historic plaque.
