The 22 1/2 Mile Road Bridge is a historic metal truss bridge that was built in 1906. The bridge was closed to all traffic in recent years due to deterioration. This bridge could be repaired and restored for continued light vehicular use, giving the bridge function once again, while also ensuring that this important historic bridge remains a part of the Calhoun County landscape.
