Across the county line, US 31 continues eastward, passing north of the community of Interlochen, intersecting the former M-137, which connected to Interlochen State Park. The highway then angles northeasterly north of Duck Lake and south of Silver Lake. A few miles farther east, US 31 meets M-37 at a location known as Chums Corners. The two highways join and run northward through the unincorporated community. It passes Turtle Creek Stadium, the home stadium for the Traverse City Pit Spitters, a minor-league baseball team. From there, US 31/M-37 runs downhill into Garfield Township. In this area, the highway passes through a cluster of retail stores and car dealerships near the Grand Traverse Mall. North of the intersection with 14th Street, the trunkline follows Division Street into Traverse City. From there it runs to the east of Grand Traverse Commons, the former Traverse City State Hospital, before US 31/M-37 meets Grandview Parkway next to the West Arm of the Grand Traverse Bay.
