In Kansas, Signs indicating access restrictions are posted on the on-ramps to interstates and some (but *not* all) non-interstate freeways. K-10, for instance, has posted access restrictions on the Douglas County segment, but not on the Johnson County segment. Both sections of K-10 in question, however, are clearly freeway, and properly tagged as "motorway" in OSM. Back to the question at hand (how to treat super-two facilities): While KDOT *state* maps do not distinguish between 2-lane controlled access and non-controlled access facilities (and, since 2010, the same applies to non-interstate 4-lane facilities,) *county* level maps published after 2007 do show controlled-access facilities, regardless of the number of lanes. Those county maps show US 169 between Chanute and Iola as a controlled-access facility. Thus, it is properly tagged as motorway under Chris's second suggestion ("If it has full access control, it's a motorway. If not, it's not one.")
