County Road Closures

Information current as of: 5/5/2022.  Please check NWS for weather conditions and plan your travel accordingly.  We strive to keep this page up to date with seasonal closures, but please also reference the snow removal link to review our snow removal policy and priorities.


Seasonal Closures:

Virginia Lakes Road:  Open

Saddlebag Lake Road: Closed (check Caltrans page for status of 120W)

Lundy Lake Road: Open 

​Rock Creek Road: Open

NOTE: Many Forest Service roads ARE STILL impassable in wheeled vehicles. Although certain sections of roads may be dry, large snow drifts exist in the upper elevations and shaded locations, and are impassable in wheeled vehicles. Check local weather forecasts before any visits to remote areas, and be prepared.

Actual road closures and activity will be updated periodically – please consider these notices as warnings, and plan accordingly. Contact the Town of Mammoth Lakes for the status of roads within the town's limits (760-934-8054). Currently, Mono County does not manage snow removal in that area.

Please check  for current information on the status of Caltrans maintained roads.  


Tioga Road administrative access was authorized on May 3, allowing NPS and Yosemite Hospitality employees access to Tuolumne Meadows and other facilities in the Tioga corridor. The bulk of the seasonal workforce onboards on May 9. 

Facilities Management (FM) staff have been assessing facility condition in Tuolumne Meadows and the following tasks are underway: 

Snow plowing of side roads, improving plowing on Tioga Road 
Hantavirus inspection, cleaning, and clearance of buildings 
Snow shoveling of tent cabin platforms 
Assembly of the water treatment plant 

Due to cold temperatures at night at Tuolumne Meadows, the wastewater treatment plant’s three internal tanks are frozen, as are the external ponds across the meadow.  Additional thaw is needed before crews can work on the plant. 

Employee safety and resource protection are paramount to the annual effort to open the Tioga Road to the public.  We remain confident that the Tioga Road will open to the public by Memorial Day weekend, weather permitting.
