Judging by the HUGE number of slatposted (verticle, as opposed to
horizontal) route numbers in this system, I'd say the vast majority of
these are managed as a trail.  Albeit passable by something with decent
ground clearance (most vehicles will have trouble; I had a Kia Sportage
with a little over 8" of ground clearance and still managed to hit frame to
ground more often than Carfax probably shows on these).
