Currently a highway linking Port Huron to Indianapolis, I-69 is planned to extend all the way to Texas, creating a second Interstate link between Canada and Mexico (Interstate 5 along the West Coast is the first).  Here's the exit list for the Michigan portion of I-69, from south to north (although when you leave Lansing, it goes from west to east, a violation of rules dealing with odd-numbered interstates).
