Concurrency fixed in #152706294.

MoDOT's official travelway definitions are wrong, as they claim K ends at N rather than running concurrently with it to the west some distance.

You can clearly see the route marker for K here in Streetside: https://www.bing.com/maps?cp=37.214245%7E-89.541025&lvl=21.6&pi=-3.8&style=x&dir=130.5
