From Corbin townsite, we drove a Subaru south to the washout at 10.5 km. If you have a HC 4x4 you can very carefully drive the heavily washed-out road for ~200 m through the washout, which is basically "Squall Creek" taking over the road prism (see photo). The bridge at ~12 km is a tough one. It is deteriorating drastically, and if you are driving a truck, you actually need to get your right tires on the stringer log to cross it (see photo). The next bridge at ~13 km is also in very rough shape.

We biked from the 10.5 km washout to 14 km where we climbed Corrigan and Francis. We met a truck at 14.5 km who came up from the south (Lodgepole FSR) and mentioned he has driven over those sketchy bridges and the road we just biked many times. I would use a large degree of caution at those bridges, or just bike the road as we did.

From Corbin, this road is in good shape to the Barnes Lake turnoff at 4.5 km. After that it deteriorates, but was in decent shape for us to get a Subaru to the big washout at 10.5 km.

Of note, this road might benefit from subdividing into segments as its conditions (and name) varies considerably. Most access comes via the Lodgepole/Harvey arriving at what this site labels km 37. Heading south from here, the road is in good, 2WD shape to ~km 65 and the junction with the Couldrey FSR. From the Couldrey FSR to the border it is Somewhat Degraded, especially the last couple km to the old border crossing where it gets muddy with some wet spots. South of the junction with the Kishinena FSR (km 53) its name changes to the Flathead Border FSR. Heading North from the Lodgepole, the road is called the Upper Flathead FSR and numbers count up. This road is also rougher with some rocky spots that have been underwater in recent high water events. The bridge at ~km 21.5 is in poor shape (see photos) but was crossed with a spotter. We left the road at ~km 17.5 to head up the McLatchie so cannot comment between there and Corbin, though I have heard its high clearance 4WD only.

Road in ok condition. Lots of rocks in some places. A few sketchy bridges, but passable even with a full size truck. Spotter preferred.
