At this interchange with I-96, US 31 has its southernmost business loop as U.S. Route 31 Business runs westerly and northward into downtown Muskegon. The main freeway continues through the suburban eastern edge of the city through several interchanges, including one with M-46 (Apple Avenue). Just south of the Muskegon River, the business loop merges back into the main freeway. US 31 crosses the river and turns northwesterly through forests. The freeway passes to the east of Michigan's Adventure, an amusement park, and crosses the White River near the communities of Whitehall and Montague; a business loop curves off to the west to connect the two communities with the freeway. In this area, US 31 runs through the southern portion of the Manistee National Forest as well.
