Bridge construction was delayed over Grand River flooding in spring 2013. In 2014, the new interchange at I-96 was completed. The steel beams spanning the river were not set in place until August 2014. MDOT announced in August 2015 that they would hold a "M23.1k Run" on October 3, 2015, before the highway opened to traffic. The agency limited participation to 231 runners. The highway opened to traffic on October 30, 2015, and the total cost for M-231 was estimated at $180 million.
