Caltrans has closed U.S. 395 from Bridgeport to the 167 Junction at Mono City due to whiteout
conditions. 182 out of Bridgeport is still a full closure. In addition, the highway remains closed
from Lee Vining to Bridgeport due to avalanches in the burned area above Mono Lake. The
highway is open from Bridgeport north. There is no estimated time for opening the section of U.S. 395 north of Lee Vining where a series of avalanches took out transmission facilities and crossed the road, burying sections of the road under 30-40 feet of snow and debris. The best estimate is the road will be closed in that area for at least this week and into next week.
S.R. 167 from U.S. 395 to the Nevada state line is closed.
U.S. 395 in the Walker Canyon has been reopened following avalanche concerns.
Benton Crossing Road is closed.
