From socal_parrot in #118, the news was "Several hundred vehicles" are stranded between Snow Valley and Big Bear along Highway 18; this area is called the Arctic Circle? I'm not familiar with the area enough to know where Bear Valley Cutoff is.
Bear Valley cut off in south of Hisperia out in the desert off I-15. Behind the mountains, or north of the mountains in the desert.
Dangerous situation, I hope help arrives to these stranded people before their gas and car heaters go cold.
That would be the "front" way, were folks from San Bernadino and environs would typically take.

There's a "back" Hwy 18. If you follow the road through town, and past Bear Mountain, you can take it there. IIRC, Bear Valley cut off is down in the valley once you get off the mountain. You can take it to Victorville, and catch I-15 that way, or the 138 and head to Palmdale.
