I-91 is one of two Interstates (I-87 and A-15 being the other) that directly transition into a Quebec Autoroute. A third seamless connection will be created when Autoroute 35 is completed southward to the international border opposite Interstate 89.

I-94 east at I-69 - Marshall, MI
Interstate 94 crosses paths with I-69 on the rural outskirts of Marshall, Michigan. 11/05/11

I-69 and I-94 come together twice in the state of Michigan. Two-digit Interstates meeting twice within a single state is a rare occurrence. Other examples include the end points of I-12 with I-10 in Louisiana and I-93 and I-95 both south and north of Boston, Massachusetts.
