It depends on which route you take.
If you take I-94 through Minneapolis and across North Dakota, your halfway point is on I-94 in eastern Montana, between Glendive and Miles City.
If you take I-90 across southern Minnesota and South Dakota, and then US-212 to bypass most of northeastern Wyoming, your halfway point is on US-212 near Broadus, MT, in the southeast corner of Montana.
Either way, your halfway point is in eastern Montana.
