The Murray FSR or Kinuseo Falls Road depending on who you ask. Maintained, usually kept open until approx the Km 21 gas plant in the winter but not usually further. Generally good (for NEBC, ie, bad, but tolerable) condition, a great deal of traffic for the few kms between the Quintette mine and various gas facilities, but then quieter. Road surface turns into coarse/conglomerate river rock after about the Km 21 mark which makes for a slow, rough, loud drive, but I have clocked the driver of a Mini at over 80kph in there and she seemed to be having a great time, so, I mean, you can do whatever you want in life, I guess.

Note the Kinuseo Falls viewing platform is closed for repairs and isn't expected to reopen until 2026.
