MDOT and the Grand Traverse Road Commission (GTRC) announced in August 2019 that the GRTC would take over ownership of M-37 on the Old Mission Peninsula north of Traverse City effective May 1, 2020. Once the change was completed, MDOT would remove M-37 from the US 31 concurrency through Traverse City, truncating the highway to terminate in Chums Corners. In November 2019, Peninsula Township officials went on record in opposition to the transfer. The City of Traverse City supported accepting jurisdiction of a section of M-37 north of US 31/M-72 to the city limits in February 2020. MDOT announced a public hearing for May 21, 2020, to take public comment on the transfer. Because the highway segment in question is a Pure Michigan Byway, the department is required to conduct at 30-day review of the transfer; after the transfer Center Road would become a county road, and only state trunkline highways are eligible for byway status under state law.
