In southern Kent County, M-37 follows Cherry Valley Road through Caledonia. As the highway transitions to Broadmoor Avenue, the landscape also transitions from rural to suburban. North of 76th Street, Broadmoor widens to a four-lane boulevard which passes a campus of Davenport University near the M-6 freeway on the outskirts of the Grand Rapids area. This section is dominated by light industrial complexes west of the Gerald R. Ford International Airport in the suburb of Kentwood. These complexes change over to retail establishments north of 32nd Street. At 28th Street, Broadmoor Avenue ends, and East Beltline Avenue begins. This same intersection also marks the western terminus of M-44, which starts concurrent with M-37 in Kentwood. These two highway designations follow East Beltline Avenue between the Woodland Mall and the Centerpointe Mall. North of the malls, M-37/M-44 passes through the campus of Calvin College and along residential areas at the east end of Reeds Lake. The intersection of East Beltine Avenue and Fulton Street is the western terminus for M-21, a highway that runs east across the state to Flint. North of this junction, M-37/M-44 meets I-96.
