About this Bridge:
This long-span concrete bridge carries Grange Road over Stoney Creek in rural Dallas Township. Constructed in 1923-24, the structure is comprised of a single, 90-foot concrete through girder span, with arched ribs that rest on angled concrete brackets cantilevered from the concrete abutments. A series of concrete floor beams span between the two girders; these are cast integrally with the 20-foot-wide concrete deck. The arched girders feature typical MSHD detailing, with corbeled bulkheads and spandrel walls punctuated by five small arched cutouts aligned over a series of arched recessed panels. Bronze "State Reward Bridge" plates are affixed to the tops of the bulkheads. Other than the installation of Armco guardrails at the approaches, the Grange Road Bridge is unaltered.

The Michigan State Highway Department first developed plans for a long-span concrete through girder bridge with arched girders on cantilevered brackets in the 1921-22 biennium. "These designs have curved top chords and bottom chord brackets," MSHD reported in its Ninth Biennial Report, making them suitable for relatively long-span applications. The highway department touted the flexibility of the bridge, stating that arched girders with cantilevered sidewalks were suitable for urban and small-town applications.

The first curved-chord girder was a 90-foot span built in 1922 over the Raisin River at Tecumseh. This was followed in the 1920s by a series of curved girders used in single-span or multiple-span configurations. One of these new bridges was the span that MSHD designed in 1923 for this Clinton County Crossing. The Stoney Creek structure, like the Tecumseh Bridge, featured a 90-foot span. It was designed by MSHD in 1923 in behalf of the Clinton County Road Commission. The Price Brothers, contractors form Lansing, were awarded the contract to build the bridge; they completed in 1924 for $25,893.09, of which the state and county paid almost equal amounts. Since its completion, the Grange Road Bridge has functioned in place in essentially unaltered condition on this secondary road. With its 1923-23 construction date, its 90-foot span and its integral sidewalk, the Grange Road Bridge is today representative of the state's MSHD-designed, arched through girders.
