Interstate 80 is closed in both directions in Placer County as crews try to clear multiple car crashes and snowfall in the Sierra Nevada Mountains.

Crash reports began coming just before 2:30 p.m. near Donner Summit, according to California Highway Patrol officials.

Lanes are closed in both directions from Kingvale Road to Donner Lake Road. Chain requirements remain in effect in both directions along that stretch of road, too.

CHP officials have not yet released an ETA for when the roads will reopen.
