As the freeway approached Kent County, it met the western terminus of M-11 which was the former routing of US 16 through the Grand Rapids metropolitan area. I-196/US 16 continued eastward around the north side of the metropolitan area through the suburbs of Walker and Comstock Park. The freeway intersected the contemporaneous routing of US 131 along the East Beltline and curved south through the eastern edge of Grand Rapids to meet the end of I-96 east of downtown. There I-196 ended and US 16 was transferred to the I-96 freeway. I-96/US 16 continued southward intersecting Cascade Road, which was previously US 16. Cascade Road east of this interchange meets the westernmost part of Grand River Avenue, which carried US 16 east continuously to Downtown Detroit.
