From I-96, the M-99 continues north through residential neighborhoods into Lansing as Martin Luther King Jr. Boulevard. The highway travels northeasterly through the southern side of the capital city, as far as Jolly Road. There it turns northward through the Old Everett Neighborhood. The street is bordered by commercial properties in this area. M-99 widens into a boulevard as it passes the T-intersection with Victor Avenue, passing through the Moores Park neighborhood before crossing the Grand River. North of the river, the highway is bordered by the site of the former Lansing Car Assembly plant, which for a century produced Oldsmobiles and other GM cars. M-99 ends at a junction with I-496 just north of the assembly plant area at exit 5; Martin Luther King Jr. Boulevard continues north from this interchange as the Capitol Loop.
