Driveable to the 5.2km mark where an unnamed creek has washed out a fair bit of the road. It appears that some work has been done to get ATVs over and a determined driver could probably get a small truck through, but we didn't risk it as we just wanted to do some reconnaissance. The road up this point is narrow in spots, overgrown and has one or two small off camber sections. Otherwise, nothing crazy needed to drive it.
