Caltrans District 3 crews turned all westbound Interstate 80 traffic at the Truckee and Donner Lake Interchange on December 24, 2025, between 9:16 p.m. and 10:16 p.m. UTC due to multiple vehicle spin outs, according to an X post from @CaltransDist3. Motorists face significant delays with no current estimate on when westbound traffic will be released, as stated in the Caltrans District 3 traffic alert posted during this 59-minute period. The diversion aims to manage unsafe conditions at the interchange, located in the Sierra Nevada region near Lake Tahoe.
