A rockslide around noon on Monday forced the closure of Highway 140 into Yosemite National Park, park officials said.
On Tuesday, spokesman Scott Gediman announced the closure would remain in effect until at least the end of the June 17-18 weekend.
The rockslide was reported a mile east of the El Portal Road (Highway 140) and Arch Rock Entrance to Yosemite. That entrance was closed.
No injuries or vehicle damage were reported as a result of the slide. Officials first said the road would remain closed for at least 24 hours, then updated that closure to indefinite on Tuesday.
The rockfall damaged the road, guard rail, and related infrastructure, park officials said.
