Picking up hwy 20 from I-80 westbound the hwy 20 road is narrow two lane with slim shoulders if I remember correctly and of course scenic and twisting thru the mountains and many spots are marked where fatal crashes occurred. Highway 395 north of Reno is often closed now due to the Beckwourth Fire Complex that has crossed the hwy and buildings have burned in Doyle that is on 395. Sometimes they use a pilot car when opening the highway north of Hallelujah junction at 395 and hwy 70. Caltrans DOT road info is usually up to date on road closures with maps and sometimes photos. This is very recent info from the fire incident website at
