County Road Closures

Information current as of: 5/26/2022.  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: Open (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 (the continuation of Highway 120 through the park) is scheduled to open to vehicular traffic on Friday, May 27, 2022, at 9 am. A reservation is required to drive into *or through* Yosemite between 6 am and 4 pm through September 30; this includes travelers passing through the park on Tioga Road. Visit for more information. 

Drinking water and flush toilets will *not* be available when the Tioga Road opens; these services may be available within a week.  Visitors should bring their own drinking water.  Vault toilets will be available along the Tioga Road corridor except for construction zones. 

Please pack your patience!  There are many major construction projects occurring in the park this summer: construction has already begun and will continue through fall.  Construction activity will be heavy on the Tioga Road during all of May and June. 

Tioga Road construction will involve pulverizing of old asphalt beginning in early June, paving beginning in mid-June, and shoulder work throughout the summer.  Heavy equipment, including trucks hauling asphalt or base material, may be present at any time.  Construction progress is weather-dependent (particularly temperatures) and construction vehicles may be given priority at the entrance gates. 

All vehicles should be prepared for driving on unpaved surfaces, traffic delays, one-lane roads, flaggers, and pilot vehicles.  Parking in construction zones is limited to designated areas and will be strictly enforced, particularly areas designated “no parking”.  Please obey all signs and drive slowly/carefully in construction zones. 

Traffic delays up to 30 minutes during daylight hours and up to 60 minutes at night could occur: Road Work in Yosemite - Yosemite National Park (U.S. National Park Service) ( .
