Road Work

Road work ahead
The National Park Service (NPS) will be making repairs on numerous roadways throughout the park. 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.

Current Projects


El Portal Road - Culvert Installation (Spring 2017)

Culvert installation will begin on the El Portal Road between the intersection with the Big Oak Flat Road and Pohono Bridge at 6 am on Monday, April 24, 2017.

There will be one (alternating) lane open with up to 30-minute delays. Work will last for up to two weeks.

Yosemite Valley Parking and Road Improvement Project (Fall 2016 - Spring 2017)

After two years of design and planning, the National Park Service is launching a wide-ranging project to improve traffic circulation and parking in Yosemite Valley. Beginning September of 2016, the park will re-construct the Yosemite Village Day-Use Parking Area to improve wayfinding and efficiency. As a result of temporary road closures associated with this project, detours will begin September 6, 2016. Download a PDF with map and other details [600 kb PDF].

A segment of Northside Drive will move south, allowing safe pedestrian access from the parking area the Yosemite Village. The parking area will move farther away from the Merced River, enabling over an acre of wetland habitat restoration. Construction of a roundabout will enhance traffic circulation. Ultimately, the project will provide a more intuitive, scenic, and enjoyable setting for park visitors as they arrive in Yosemite Valley.

The project will continue in early 2017 with improvements to the Yosemite Falls parking area (west of Yosemite Lodge) and the Camp 4 parking area. During the remainder of 2017, the park will rehabilitate portions of Northside and Southside Drive.

This project is part of a comprehensive suite of actions prescribed in the Merced River Plan to protect and enhance the Merced River corridor. The National Park Service approved the Merced River Plan in 2014 after an extensive public involvement process.
