Thanks for your comment, Kovoschiz. 

Is this the segment you are referring to as a "braided ramp"? https://www.openstreetmap.org/way/93096386 - IMHO this segment is a c/d road with frontage access and thus I've set it as secondary. In regard to the fork: https://www.openstreetmap.org/way/160581522 - I see it is a transition lane that facilitates traffic movement between two parallel through-routes (the mainline and its c/d road). Also want to note that router support is subservient to data integrity. 

Happy mapping!
