Only passable by foot, bike or horse for most of it.
Tons of Alder/new growth makes for very slow bike ride
Multiple major washouts and numerous trees down also, so expect to carry bikes multiple times.
Bridge across Kellie Creek Removed also.
You could take a dirt bike or bike across them, quad or heavier is at getting riskier.
The area is only accessible by bike or foot anyhow with the main road gated and lockblock walls at Km Zero anyhow so unless you already had a vehicle in here you are stuck with bike or foot anyway
