The Capitol Loop is a state trunkline highway running through Lansing, Michigan, in the United States that was commissioned on October 13, 1989. It forms a loop route off Interstate 496 (I-496) through downtown near the Michigan State Capitol complex, home of the state legislature and several state departments. The Michigan Department of Transportation (MDOT) has labeled it as Capitol Loop I-496 or CL I-496 on some maps, similar to the Business Loop Interstate nomenclature.
