Alpine County, Tuolumne County – The California Department of Transportation
(Caltrans) announced today, November 3, 2011 that State Route 108 over Sonora Pass and State Route 4 over Ebbetts Pass will be closing at 2:00 p.m. Crews will close State Route 89 over Monitor Pass at 4:00 p.m.
The closures are due to weather predictions that make it necessary to close these passes for the safety of motorists and Caltrans crews.
“Winter weather and road conditions can change rapidly. Motorists should expect the
worst conditions and be prepared. All vehicles including those with four-wheel drive or
snow tires should carry chains when traveling during snowy weather. If you don’t have
chains in your possession, you may not be allowed to proceed. When highway signs
indicate that chains are required, you must stop and install chains or risk being cited
and fined.” Said Christopher Mayfield, a representative of Caltrans.
Caltrans reminds us that for the latest road condition information you can tune your radio to the Caltrans Highway Advisory Radio (HAR) at 530 AM or 1610 AM or call our Road Condition Hotline at 1-800-427-ROAD (7623). Changeable Message Signs with flashing beacons will have information regarding the pass closures.
When traveling watch for chain control requirements on flashing signs. There are three 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.
R-2: Chains are required on all vehicles except four-wheel drives with snow tread tires.
Four-wheel drive vehicles must carry chains in the vehicle.
R-3: Chains required – ALL VEHICLES – no exceptions.
