Tioga and Glacier Point Roads Plowing Update

Snowplow working on Tioga Road with a few feet of snow

Tioga Road plowing at Porcupine Flat, April 16, 2014

Tioga Road

Snow removal began on April 16, with plows reaching Porcupine Flat.

There is currently no estimated opening date for the Tioga Road. The road is closed to vehicles, bicycles, and pedestrians when snow removal operations are underway.

A limited portion of Tioga Road will open to bicycles only on Saturday, April 19 at 6 am and will close at sunset Sunday, April 20. The road will be open between Crane Flat and May Lake junction (or beyond, if conditions permit; road closure signs will indicate the end of the opening). Cyclists should use caution, as they may encounter debris on the road, and should not proceed beyond the road closure signs. No services or facilities will be available.

Glacier Point Road

Opened to vehicles on April 14

Factors affecting plowing operations

Once plowing of the Tioga Road is completed, additional work must be completed before the road can safely be opened.

  • Avalanche zones (26 potential areas). The Olmsted Point avalanche zone requires a lot of work, including application of charcoal over the snow to help with melting and blasting the snow slab to make it safer for personnel.
  • Heavy snow pack slows the whole operation.
  • Trees that have fallen across the road and been buried in the snow. These can cause substantial damage to the equipment and result in a stop to all operations until they're cleared.
  • Rockfalls buried by the snow. These can cause substantial damage to the equipment and result in a stop to all operations.
  • Snow storms during the opening require a stop to Tioga Road operations and in order to plow and sand the park roads.
  • Road repairs, ditching, and brushing operations once snow has melted back enough.

Cars and campers in a meadow in Yosemite Valley.

Unrestricted camping is no longer allowed in Yosemite Valley because of damage it causes. The placement of campgrounds and campsites has changed over the past 75 years in response to a growing understanding of river dynamics, geologic hazards, and the park's natural and cultural resources.
