Caltrans urges drivers to avoid travel to Sierra Nevada mountains
– Caltrans Director Toks Omishakin is urging motorists to avoid non-essential mountain travel until weather conditions improve. Caltrans has closed 45 state highways since Dec. 24 due to record snowfall in the Sierra Nevada. While Caltrans has reopened 29 highways – including Interstate 80 and U.S. Highway 50, the main gateways to Lake Tahoe – roadway conditions remain challenging with extensive delays and chain controls in effect.
