There are several trailheads and access points to the MKT spur in Columbia. Traveling north, before you get to the end of the trail in downtown at Flatbranch, you will go under Stadium Blvd. at the Martin Luther King trailhead. Going west on Stadium Blvd. will take you to I-70 where there is Holiday Inn and Drury. Going east will take you to the Hampton Inn which is south of Stadium Blvd at the south east side of the MU campus. Stadium Blvd. has a good shoulder but is not without hills. We've ridden to both the I-70 corner and to the Hampton.
If you are a flatlander, one of the B&B's near downtown or the Hampton Inn may be a better option. The last route I took was to the Flatbranch Park which is just a couple of easy riding blocks to the MU campus. I cut across campus to the Hampton. It was pretty flat like the Katy and a bit less stress than all the cars on Stadium Blvd. There is a restaurant next to the Hampton also.
We've also done the trip you mentioned in the other direction. Park the car in the parking garage on Cherry (I think) just a block or so from Flatbranch Park and then ride to Jefferson City or Boonville. It cost a few bucks to leave the car in the parking garage but it wasn't too much or I'd remember that it wasn't a good deal.
