This is a 1912 half-hip Pratt pony truss with pinned connections. The bridge is composed of four panels yielding a total
bridge length of 54 feet. Original lattice railings are present on the bridge. A relatively late example of its type, the bridge features the traditional design of a pin-connected truss bridge. The bridge sits on steel caissons, which are integrated
into a protective steel plates that serve as retaining walls, together these elements forming an unusual variety of abutment. The river crossing is a swampy one here, which may account for the unusual support system.
This truss bridge
was amazingly still open to traffic at a three ton weight limit in 2006. In 2009, the bridge had finally been closed to traffic due to a critical deck condition. The future of the bridge is uncertain. Given the rarity of this bridge type in
Michigan, the bridge should either be preserved in place for continued light vehicular use, or perhaps relocated and preserved for use by pedestrians in a park or trail setting.
