the south that turns west. The lanes northbound into downtown were opened in the beginning of August, and the city held a ribbon cutting ceremony on August 19, 2010. The remaining lanes were opened the next day. Historic bridges MDOT has highlighted five historic bridges along the route of M-28 on the MDOT website. In Interior Township, Ontonagon County, the highway crosses the Ontonagon River over a bridge built in 1929. Designed by the State Highway Department and built by the firm of Meads and Anderson, the Ontonagon River Bridge is one of only three steel arch bridges in Michigan. The main span arch is long. A former routing of M-28 in Covington Township crosses the Rock River. Although this section was bypassed by a new alignment of the trunkline in 1924, the bridge remains complete "with corbeled bulkheads and six panels recessed in the concrete spandrel walls." The corbels and spandrels are decorative features found in the concrete sides of the bridge. Today, drivers cannot use the Peshekee River Bridge south of US 41/M-28 in western Marquette County's Michigamme Township. The bridge was listed on the National Register of Historic Places in 1999 as "Trunk Line Bridge No. 1" for its engineering and architectural significance. MDOT has listed it as "one of Michigan's most important vehicular bridges." It was the first bridge designed by the Michigan State Highway Department, the forerunner to MDOT, in 1914. It was bypassed by a newer bridge built over the Peshekee River on US 41/M-28 subsequently abandoned as a roadway. The replacement bridge was bypassed and demolished in 1995. The next historic bridge listed by MDOT along M-28 is over the Sand River in Onota Township in Alger County. While not visible to motorists, the bridge, constructed in 1939, is the longest rural rigid-frame span in Michigan. Most bridges of this type were built in urban locations, and soil conditions in the state limit locations for this style of bridge. The bridge over the East Branch of the Tahquamenon River in Chippewa County was built in 1926 as a "formative exercise in what would evolve into a state standard design." The bridge was built with nine lines of I-beams encased in concrete. Only one other bridge in Michigan was built with such concrete encasement.
