Drove Northbound, in reasonable condition up to bridge at 12km, which is not rated for cars/trucks (1000lb limit), nor wide enough for most, and had a large hole for half of the width of the bridge. That south part could be done in most HC SUVs/4x4s. Unsure about the rest of the road (0-12km).
Single track that’s wide enough for a small 4x4 with a couple turnaround spots. There is a rock slide just before you get to the southwest side of the ATV bridge over Walian creek, it’s left a couple boulders on the trail, it’s passable but very narrow
