We are coming from Alberta CA to Great Falls Montana,what is Hwy 89 south to White Sulphur Springs ,then down to I90 like with a 35f 5er,this would be in the summer.Thanks John R.
Don't know about US89 from the border but it is a US highway.to Great Falls but south of there it's a nice scenic drive. We cut over on US12 at White Surpher Springs east to state road 3 then down to I90
