History

Originally planned to run from Port Huron, Michigan, to Charlotte, North Carolina, I-77 appeared on the original Interstate system route numbering plan in 1957. The part of I-94 from Detroit northeast to Port Huron was originally planned as I-77 in 1957; the current I-77 was I-79. When the current I-79 was added in Pennsylvania, the I-77 designation was moved to its current route, but the I-77 in Michigan also remained in the 1958 numbering plan, so the designation followed I-90 and I-75 in order to keep it continuous; the designation north of I-77's westward turn was to have been Interstate 177. I-77 in Michigan later became part of I-94.
