Ok I live 3 miles from RST. Here is what you do. Take Exit 209 off I90 north toward Rochester. This is Hwy 63 north. The very next Exit off Hwy 63 is the RST Exit....go around the roundabout and over the freeway bridge about a mile (west) then left turn into RST. If you need a place to park over the 1/2 hour free parking, go to the Lyft/Uber lot at the north end of the main lot and sit there... no charge. Easy, beats MSP 10 x over.
