General Information

During 2025, 2026, and 2027 there will be major road construction improvements on Mineral King Road. This narrow, curvy mountain road has been in need of improvements and repaving for many years. There will be closures and traffic delays on weekdays throughout the spring, summer, and fall. See the schedules below.

In areas where road work is on-going or there are only temporary repairs, travel slowly and obey reduced speed limits and any traffic management, such as traffic flaggers.

This page will be updated as needed when major road work is happening in the parks.

See the Road Conditions page for information on all park roads.

 

Mineral King Road

General Information

Mineral King Road is a narrow, curvy mountain road. The road enters Sequoia National Park 9.4 miles (15.1 km) – approximately 45 minutes drive time – above its junction with Route 198.

In 2025 road construction will introduce road improvements. Currently, the affected section of road is approximately 8 miles (13 km) long. None of the recreation sites or services along Mineral King Road, such as campgrounds, trailheads, or private inholdings such as Silver City Resort, are within the impacted section of road. However, anyone wanting to access services in the Mineral King area will have to pass through the road construction.

Later in the year, construction sites may move and could include sections of road near and around Mineral King area recreation sites and services. Updates will be posted on this page.

Summary Of Impacts

While the road is open to public vehicles there will be construction closures and delays on weekdays. There will be no traffic impacts on weekends or holidays.

The western end of the affected road section is at the park boundary. The eastern end of the affected road section is approximately 8.2 miles (13.2 km) east of the park boundary and is approximately 1.7 miles (2.7 km) west of Atwell Mill Campground. At this time, none of the trailheads, campgrounds, or private inholdings such as Silver City Resort, are within the construction zone.

During traffic delays and closures, flaggers will control traffic. The estimated drive time through the 8 mile (13 km) section of road within the construction area is about 40 minutes for a single car. Actual times will vary based on traffic.
