hwy 299 northwest CA

Whether the road is in good or bad shape doesn't take away from the fact it is a long way across from Hwy 101 to I 5. You climb and descend over 5 passes, and there are turns and narrow in places. Is it doable`? Yes. is it a good route? I don't like it as it takes a good 5 hours to cross in either direction. But others may have different opinions and more up to date info on current road conditions and maybe road construction going on right now. I use hwy 20 from I 5, Williams, to hwy 101, Ukiah. Maybe others will chime in with more info.
