Road Work in Yosemite

Reconstructing a damaged section of the Big Oak Flat Road in March 2017.

The National Park Service (NPS) regularly makes repairs on roadways throughout the park. Additional restoration and construction projects, along with operations related to fire management and hazard tree removal can cause delays or closures along park roadways.

A Yosemite NPS Project Manager is onsite to complete regular inspections and to ensure that the work complies with our environmental requirements, as well as the goals and mission of the National Park Service. An overview of each project is listed below along with an estimated schedule of delays for each. Email us if you have any questions.
