The Michigan Department of State Highways first announced plans in 1970 to expand M-99 within the Lansing city limits. The plan called for conversion of M-99 to a boulevard between Victor and Pulaski streets, on the south side of the Grand River; after crossing the Grand River, the roadway would be split into a one-way pairing northerly to Kalamazoo Avenue, with northbound traffic along the existing routing on Logan Street and southbound traffic following Birch Street. Construction of such a routing was slated to displace of residential district and some businesses along Logan Street. Construction on this realignment began in 1973, and the boulevard routing from Victor to Pulaski opened in late 1977.
