M-21 / Plaster CreekCounty: Kent
Location: M-21 / Plaster Creek
Year Built: 1916 About this Bridge:
The Wyoming Bridge is a medium-span arch bridge in the city of Wyoming. It carries M-21 BR over Plaster Creek in an industrialized area adjacent to Roosevelt Park. The bridge is a 60-foot, filled spandrel arch, with earth fill and an asphalt-surfaced roadway that is flanked on both sides by concrete sidewalks. The elliptically shaped arch springs from massive concrete abutments. It features a tapered arch ring, which is cast integrally with the plain-faced concrete spandrel walls. The guardrails are solid concrete, with recessed rectangular panels; bronze “Trunk Line Bridge” plates are mounted one their inside walls. Although the neighborhood around the Wyoming Bridge has changed substantially since the bridge’s construction in 1916, the bridge itself remains unaltered and in good physical condition. In 1916 the Michigan State Highway Department designed Trunk line Bridge No. 58 over Plaster Creek in the city of Wyoming. Located on the trunk line route that extended south of Grand Rapids, the Kent County seat, the structure featured a 60-foot, filled spandrel concrete arch. The agency hired Grand Rapids contractors Hilding and Rabe to build the bridge. Finished later that year, the structure’s $13,146.55. Cost was borne almost equally by the state highway department, the Kent County Road Commission and the Grand Rapids Railway Company. For three years the railway company ran its inter-urban cars over the bridge, but in 1919 discontinued the line and removed its tracks. The Wyoming Bridge has since carried vehicular traffic in essentially unaltered condition.
