Caltrans Traffic Alert 

March 25, 2025 - Caltrans officials report Caltrans anticipates one-way traffic control restored on Wednesday afternoon, March 26.

Currently the long-term FULL CLOSURE remains in place on SR-140 from Briceburg to the Yosemite Cedar Lodge in Mariposa County due to a rockslide that occurred on March 17, 2025. 

UPDATE (3/24): Caltrans Geo-Tech experts finished assessing the slide area late last week & the specialty contractor was able to perform rock scaling operations to remove any loose debris.

Teichert Construction was able to begin 24/7 debris removal operations on Sunday, March 23 and aim to begin repairs to the roadway this week in anticipation of re-opening SR-140 to one-way traffic control by the end of the week/month.

Motorists should avoid this route and seek alternative highways (SR-41, SR-120) to and from Yosemite National Park.
