Shulaps Roads

Anyone know if the Sebring Peak / Rex Peak area is road accessible? My mapbook grew legs and walked out of my truck last week, and Google maps shows what look like roads in, but legal? gated? no motorized?

I tried once off Yalakom Rd. and got a ways in, but stopped by snow, so I didn't learn much. Same with a road just past where the Yalakom enters the Bridge, no joy due to snow.
