Stockton, CA…The California Department of Transportation (Caltrans) has closed State Route 4 over Ebbetts Pass, Route 89 over Monitor Pass and Route 108 over Sonora Pass for the 2019/2020 winter season as of Monday, December 2, 2019. The routes were last open to vehicle traffic on November 26, 2019. The recent storms and accumulation of snow, make the seasonal closure necessary for the safety of motorists and Caltrans crews. The weather conditions on the passes and subsequent road conditions are among the determining factors in the decision to make the seasonal closure.

Once the passes are closed for the winter, they will not be reopened until conditions warrant it. Each year, Caltrans crews work diligently to clear debris, remove snow and make highway repairs in order for the highways to reopen for summer travel.

For the latest road condition information, the radio may be tuned to the Caltrans Highway Advisory Radio (HAR) at 530 AM, 1610 AM or 1670 AM or call the Caltrans Road Condition Hotline at 1-800-427-ROAD (7623). Real time conditions are also available online and for mobile phones at http://quickmap.dot.ca.gov.

Winter weather and road conditions can change rapidly. Motorists should expect the worst conditions and be prepared when traveling in areas subject to hazardous conditions. All vehicles, including those with four-wheel drive or snow tires should, additionally, carry chains when traveling during snowy weather.

Drivers without chains in their possession may not be allowed to proceed. When highway signs indicate that chains are required, drivers must stop and install chains or risk being cited and fined.

CHAIN CONTROL REQUIREMENT LEVELS:
No Restrictions – Watch for snow on pavement.
R-1: Chains are required on all commercial vehicles (trucks or buses). All other
vehicles (cars, pick-ups, vans, etc.) must have either snow tread tires or
chains on the drive axle.
