Connectors

Most of the following connectors are unsigned,^[232] but they were inventoried publicly as part of the 6th edition of the Michigan Geographic Framework in 2006.^[233] Up through the 7th edition, MDOT used a different numbering system,^[234] which was changed in May 2008 with the publication of the 8th edition.^[235] The years below note when each connector was established as an individual component of the highway system.
