Rode this from north to south. Bridge over Tulameen River is good. Bridge over Hines Creek at ~985m is dangerously degraded but could be crossed by SxS or ATV. I walked a dirtbike across it very gingerly.
The road itself is full of ruts, loose rocks, and tight turns. It would be wide enough for an ATV or SxS, but nothing wider.
It maintains a consistently steep grade right up to 1400m where it joins CHAMPION CRK 19-22.
If you're into this kind of thing, it's an incredibly fun ascent.
