Big Oak Flat Road Closed May 2023 through June 2023, if not longer

Yosemite National Park, May 4

The Big Oak Flat Road (continuation of Highway 120 west into Yosemite) is closed from just inside the park boundary to Merced Grove.

The road will be closed at least until mid-June and possibly into July. We are working with the Federal Highway Administration to start repairs as soon as possible. Work is expected to begin mid-May.

Visitors entering Yosemite via Highway 120 from the west can reach Hodgdon Meadow and Hetch Hetchy, but not other areas of the park (including Yosemite Valley).

From Yosemite Valley, visitors can drive up the Big Oak Flat Road to reach the Tuolumne and Merced Groves of Giant Sequoias.

 

The road has a crack that is about 200 feet long and up to four feet deep. The road surface has moved two to three inches vertically and horizontally and is continuing to move.

The embankment below the road has moved as much as 15 feet downslope and has significant water flow through it.

It is not safe to open the road even to limited traffic, and doing so would likely lead to additional road failure.The road will be closed at least until mid-June and possibly into July. They are working with the Federal Highway Administration to start repairs as soon as possible.
