For a week in November, subsurface composition tests will occur at five locations along the 15.29-mile section of the Mineral King Road that is within Sequoia National Park. The Federal Highway Administration is gathering data regarding depth of bedrock in key locations along the road in preparation for upcoming road rehabilitation.
Public access to the Mineral King area closes for the season Wednesday, October 30, 2019, so visitation interruption will be minimal. The work will primarily affect cabin residents traveling to and from Cabin Cove, Silver City, and Mineral King during a six-day period: Monday to Sunday, November 4 through 10.
This work will consist of drilling 8-inch diameter holes up to 70 feet deep using a truck-mounted drilling rig.
Due to the narrowness of the road, there may be periods when it is impassable to vehicles due to the size of drilling equipment. The Federal Highway Administration will provide local access to Mineral King and Silver City cabin owners, business owners, and their guests and contracted workers.
Local traffic will be allowed through the work zone daily at 8 a.m., noon and 4 p.m. with emergency traffic as needed.
