The bridge company was the second most prolific metal truss bridge builder in Michigan in the 19th century. The existing structure is a single span, through Pratt truss, having eight panels at 16 feet, 3/4 inch, for a total span length of 128 feet 6 inches, center to center of pines. A determination of eligibility has been received from the National Register."
