context_page_description: M-137 was a state trunkline highway in the US state of Michigan that served as a spur route to the Interlochen Center for the Arts and Interlochen State Park. It started south of the park and ran north between two lakes in the area and through the community of Interlochen to US Highway 31 in Grand Traverse County. The highway was first shown without a number label on maps in 1930 and labeled after an extension the next year. The highway's current routing was established in the 1950s. Jurisdiction of the roadway was transferred from the Michigan Department of Transportation to the Grand Traverse County Road Commission in June 2020, and the highway designation was decommissioned in the process; signage was removed by August 2020 to reflect the changeover.
context_section_description: A highway along the route of M-137 connecting US 31 south to the state park was added to the state highway system during the first half of 1930, initially lacking a designation label on the state maps of the time.
  This routing was extended by 0.9 miles (1.4 km) and labelled as M-137 on maps in 1931. The former route through the campus of the Interlochen Center for the Arts was abandoned as a roadway on March 26, 1956, after M-137 was realigned to pass to the east of the school and extended further south through the state park area.
  On April 30, 2020, the GRCTC was to vote on a resolution to accept jurisdiction over M-137 from MDOT, effective June 1, 2020; the board approved the resolution. MDOT announced on August 6, 2020, that jurisdiction had been transferred at the beginning of June and that all M-137 signage had since been removed.
