About this Bridge:
The bridge is a 55-foot, filled spandrel arch, with earth fill and an asphalt-surfaced roadway that is flanked on both sides by grassy strips. The elliptically shaped arch springs from massive concrete abutments. It features a tapered arch ring, which is corbeled slightly from the spandrel on each side; the guardrails are solid concrete, with incised rectangular panels. Other than the installation of Armco guardrails on wooden posts inside the original concrete walls, the Iron River Bridge remains in essentially unaltered condition.

In March 1880 R. L. Seldon and his son opened the Iron River Mine on the bank of the Iron River. The mine rapidly prospered, and in 1881 Donald and Alexander McKinnon platted the town of Iron River nearby on the river’s west Bank, in anticipation of the influx of miners to the area. The town too flourished in the 1880s, soon expanding across the river. As the only incorporated village in newly formed Iron County, it was designated the county seat in 1885. Iron River later lost the county seat to Crystal Falls and eventually lost its economic base after a mining depression in the wake of the Panic of 1893. After the turn of the century, however, Iron River again flourished with the resurgence of the mining industry. The village built a new sewage system in 1905 and an electric network in 1908.

Flowing through the center of town, the Iron River had historically formed the major impediment to travel between the town’s two sides. The first bridge was built across the Iron River here soon agter the village’s platting in the 19th century. But population growth after 1900 and the designation of a state trunk line through town in 1913 placed additional strain on the existing bridge. By the mid-1910s, the village had begun to consider a replacement span for the Iron River Bridge. At the town’s request, MSHD engineers designed this 55-foot arch bridge, designating it Trunk Line Bridge No. 191, and awarded a contract for its construction to the Hoose and Person Construction Company of Iron Mountain. The contractors completed the structure in 1917 for a total cost of $20,343.16, of which the village paid over $13,000.

In 1998, US-2 was relocated to the north , and this bridge now carries local traffic on Genesee Street which is the main street in Iron River. Since its completion, the Iron River Bridge has carried increasingly heavy city and regional traffic. In the 1920s the route was incorporated into US-2, and in 1926 Iron River was incorporated as a city. The Iron River Bridge is historically significant, and technologically significant as an unaltered, relatively early example of concrete arch bridge construction by the state highway department – one of the first dozed such structures built by MSHD.
