It was in the 60's not the 90's. Lowered to 55 in the Nixon admin and slowly climbing since then.
Shortly after Clinton signed the National Highway System Designation Act in '95. Montana did indeed have a "reasonable and prudent" speed limit set on its (very rural!) highways. It didn't last due to how vague the phrasing was.
