Four States Border Michigan
Michigan touches four states — but its unique two-peninsula shape makes the count feel different depending on which peninsula you're on.
The Four
| State | Border Type | Peninsula | Key Crossing |
|---|
| Ohio | Land (southern) | Lower | I-75, I-80/90 (Turnpike), US-23, US-24 |
| Indiana | Land (southwestern) | Lower | I-80/90, I-94, US-12, US-20 |
| Illinois | Water (Lake Michigan) | Lower | Ferry (Ludington↔Manitowoc — WI, not IL); no direct road |
| Wisconsin | Water (Lake Michigan + Lake Superior) | Both | Ferry (Ludington↔Manitowoc); Bridge (I-75 Sault Ste. Marie → ON, not WI) |
Wait — Illinois?
Michigan's Lake Michigan shoreline faces Illinois — but there's no land border. The states meet in the lake. Legal boundary: midline. Practical crossing: ferry or drive around (Chicago or Upper Peninsula).
Canada Too
Ontario borders both peninsulas: Detroit River (Detroit↔Windsor), St. Clair River (Port Huron↔Sarnia), St. Marys River (Sault Ste. Marie↔Sault Ste. Marie). Two bridges, one tunnel, one ferry.
Peninsula Perspective
Lower Peninsula: Borders OH, IN (land); IL, WI (water); ON (water)
Upper Peninsula: Borders WI (water + land at Menominee River); ON (water)
Four states. One international neighbor. Two peninsulas. Two Great Lakes. Pure Michigan.
