St. Joseph Valley Parkway and I-196 US 31 and the St. Joseph Valley Parkway crosses into Michigan from Indiana southwest of Niles and parallels the St. Joseph River as the two run northward through southwest Michigan. The freeway passes through farmland before crossing US 12 at the first of a set of three interchanges located between Niles on the east and Buchanan on the west. US 31 crosses the river north of the interchange with Niles–Buchanan Road. North of the Walton Road interchange, the freeway turns northwesterly to recross the St. Joseph River near Lake Chapin south of Berrien Springs. The parkway curves around the west side of town before crossing the river for a third time. As US 31 continues northward parallel to the river, it enters the eastern fringes of the Benton Harbor–St. Joseph area. The freeway continues north of Napier Avenue and curves to the northwest to an interchange with Business Loop I-94 (BL I-94) and I-94, merging onto the latter. I-94/US 31 runs concurrently on a northeasterly course before meeting the southern end of I-196 in Benton Township. At this trumpet interchange, I-196/US 31 runs north from I-94 and passes to the west of the Point O'Woods Golf & Country Club. It continues northward in rural Berrien County through farm fields. The trunkline turns northwesterly near the Lake Michigan Hills Golf Course and crosses the Paw Paw River.

At the community of Lake Michigan Beach, I-196/US 31 meets the northern terminus of M-63 at exit 7, and the LMCT joins the freeway for the first time. North of this interchange, the freeway parallels a county road (A-2, the Blue Star Highway) that is the former route of US 31. Further north, I-196/US 31 crosses into Van Buren County and assumes the Gerald R. Ford Freeway name. The inland side of the freeway is forested while the lakeward side is predominantly either forest or fields. As it approaches South Haven, the freeway passes near the Palisades Nuclear Generating Station and Van Buren State Park. North of the power plant and park, the freeway turns farther inland to bypass the city of South Haven. There is an interchange on the south side of town that provides access to BL I-196 and M-140.
