This historic bridge was demolished and replaced in 2011 by Calhoun County Road Commission!

This is the longest of only two straight chord concrete through girders remaining in Calhoun County. The bridge is two spans, and is thus historically significant as one of very few remaining multi-span concrete girders in Michigan. The bridge was built in 1920. The contractor was A. R. Morrison from Port Huron, Michigan. It was built as a State Reward Bridge, and the plaque on the bridge lists it as number 23, making it an early example of a bridge built under the State Reward program. This girder is the type in which inset rectangles appear only on the outside of the girders. The bridge is in good overall condition, although some spalling is starting to show.

Although Calhoun County is home to the nationally recognized first of its kind Historic Bridge Park, and Calhoun County has also been kind enough to store numerous historic bridges from other counties that would otherwise have been demolished, Calhoun County's actual commitment to preserving its own on-system bridges is somewhat lacking. Of the several remaining historic bridges, none have been rehabilitated recently (and all are in need), and this beautiful historic bridge was demolished and replaced. The replacement bridge is an ugly set of pre-stressed concrete box beams with the appearance of little more than a slab of concrete. It will look like nearly every bridge structure built in the past 20+ years. The replacement bridge as drawn in the bid package is shown below. A photo of the replacement bridge is also shown below.
