USFS news releases

MONO AND INYO COUNTIES– The California Department of Transportation (Caltrans) has, or has scheduled, closure for the following passes:


  • State Route 203 (SR-203) from Mammoth Mountain Inn to the Mono/Madera County Line is now closed for the winter season.
  • State Route 168W (SR-168W) (Bishop Creek) will temporarily close at the winter gate just above Cardinal Village for maintenance work and incoming inclement weather on Monday, November 19th at 9:00 a.m. The reopening of this route is dependent upon the completion of road work and favorable weather.

Several factors influence the temporary closing, opening and seasonal closures of our pass roadways.  Storms, accumulation of snow, and road conditions are all considered in the decision-making process by Caltrans leadership. Yosemite National Park confers with Caltrans on SR-120 (Tioga Pass) to coordinate the closure of park entrance gates as well as Caltrans winter closure gates.

Additional passes under the responsibility of Caltrans District 9 and subject to temporary and permanent closure at any time include; SR-89 (Monitor Pass), SR-108 (Sonora Pass), SR-120E (Mono Mills Road), SR-158 (June Lake Loop, north and south junctions), SR-168E (Westgard Pass), and SR-270 (Bodie Road).

For the safety of motorists and Caltrans crews, continual updating of these passes will be assessed until the seasonal closure of each is decided.

Caltrans reminds drivers to carry chains and to be prepared for winter driving conditions. Not having chains in your car, even if four wheel drive, is a punishable offense. Motorist safety kits should contain blankets, water, food, a shovel, gloves, a flashlight, and sand or kitty litter to provide traction in case your vehicle becomes stuck. The traveling public is advised to drastically slow down in heavy winter conditions and proceed with caution.

For the latest road condition information, visit the Caltrans QuickMap site available for download online and on mobile phones or call the Caltrans Road Condition Hotline at 1-800-427-ROAD (7623). Changeable Message Signs with flashing beacons will have information regarding the pass closures visible along the highways.


For the safety of workers and other motorists, please Be Work Zone Alert.
