Incline, CA…The California Department of Transportation (Caltrans) has issued a long-term full closure of State Route 140 (SR-140) near Briceburg in Mariposa County as the result of a debris slide event. At approximately 10:00 p.m. on Monday, March 17, 2025, a debris slide occurred along SR-140 across both lanes resulting in an immediate full closure of the highway.

Together with Mariposa CHP, Caltrans established road closures just west of the slide at Savage Trading Post in Briceburg and to the east of the slide at the Yosemite Cedar Lodge in the community of Incline.

Overnight and early into Tuesday morning there was additional movement with the slide. As a result, Caltrans and CHP decided to take extra precautionary measures to ensure the safety of the traveling public, maintenance workers and first responders by keeping the closures in place until Caltrans Geo-Tech and Highway Operations staff could further assess the slide this week.

In response to the slide event Caltrans has notified the local school districts, sheriff and police, CAL-Fire, Yosemite National Park (YNP), Yosemite Area Transportation System (YARTS), and the local elected officials of the long-term closure. Caltrans will have a long-term closure in place on SR-140 with no current estimated time of re-opening while work is performed to further assess the slide and perform the debris removal and any needed repairs to the roadway.

Caltrans will be providing real-time updates via our social media accounts, news releases, and through our Caltrans QuickMap app for mobile devices. Motorists will be provided closure and detour route updates with use of overhead changeable message signs (CMS) along State Routes 41, 49, 99, and 120, along with weekly traffic advisories.

In the meantime Caltrans is asking motorists to avoid this stretch of highway until the needed repairs are finished, to exercise patience, and seek alternative detour routes along SR-41 and SR-120 into Yosemite National Park.

Caltrans top priority in this situation is the safety for the traveling public, our partner agencies, staff, and the contractor performing the debris removal and highway repairs.

The work schedule is subject to change due to traffic incidents, weather, availability of equipment and/or materials, and/or construction-related issues. Caltrans reminds motorists to #KnowBeforeYouGo by checking quickmap.dot.ca.gov for real-time traffic and highway conditions prior to travel.
