Interstate 296 is the hidden designation for a 3.4 mile section of U.S. 131 north from Interstate 196 to I-96 in central Grand Rapids. U.S. 131 extends south from I-296 as a freeway to Kalamazoo and Portage and north to Cadillac and Manton.
Interstate 296 acknowledged on the 1978 Michigan Official State Map
Until 1979 Interstate 296 was co-signed along U.S. 131 in Grand Rapids with the exception of the long two-lane exit ramps to I-96 west and from I-96 east. Signs for I-296 were removed at the request of Michigan and as approved by AASHTO during the October 1979 meeting.
