Road Construction

Road construction in Sequoia and Kings Canyon National Parks generally takes place in summer months. In addition to general maintenance and plowing of steep mountain roads, projects to improve and widen roads also take place. When this happens, there may be delays related to construction projects.

2022 Construction Projects

Tunnel Rock Trails Maintenance Work

Trail Crew will be continuing work on Tunnel Rock beginning October 11th. The Tunnel Rock area will be an active construction area through December 23rd. There will be construction zone warning signs placed along the road. Occasionally, there will be flaggers on the road for short periods of time while personnel and heavy equipment are active on or near the roadway. While passing through the area, please observe the 15 mph speed limit for the safety of our fellow employees and our visitors. Parking at Tunnel Rock will be closed during the weekdays. On the weekends and holidays, parking will be opened partially or completely based on project staging needs. A small area of the Potwisha overflow parking will also be used for staging materials.

Pavement Preservation Work

A large-scale road preservation project is underway in both Sequoia and Kings Canyon National Parks that will continue throughout the summer and fall. Stretches of road will be sealed and resurfaced, including pavement in some parking areas. If you encounter one of these construction zones, please plan on a delay of up to 30 minutes during the day and one hour at night.

Work will continue throughout the park this week. Please see below for a list of dates and affected areas.

Tenmile Road and Bridge Project (Sequoia National Forest)

Beginning Monday, September 26, 2022, a temporary road closure will be put in place along a portion of Tenmile Road between Quail Flat and Tenmile Campground in the Hume Lake Ranger District, Sequoia National Forest. Forest visitors can access Hume Lake and other recreation sites north of and including Tenmile Campground via HWY 180 and Hume Lake Road. Tenmile Road provides access to several popular Sequoia National Forest developed recreation sites around Hume Lake and along Tenmile Creek. This temporary road closure is just the start of the larger Tenmile Road and Bridge project. Fresno contractor Yarbs Grading and Paving, Inc. will be doing the work; they expect to finish this first segment by October 5, 2022.

Additional segments of Tenmile road will be closed as they are repaired pending supply availability and weather conditions. For more information on this project, please visit:

Pacific Gas & Electric (PG&E) Electric Work

Currently, PG&E is replacing aging underground electrical lines along the roads in the Cedar Grove area. Expect average delays of 15 minutes, with traffic control. Work will not occur on weekends, on holidays, or on Fridays prior to holiday weekends. Work will continue through the summer and into the fall and may include power outages.

Winter Road Closures and Plowing Operations

Winter snowfall always brings delays and closures, with some roads closing on an annual schedule and other closures occurring related to snow or hazardous conditions.

General Information about the Generals Highay

The Generals Highway was completed in 1935 and is the primary artery through Sequoia and Kings Canyon National Park, in Tulare County, California. The Generals Highway is a narrow, winding road that was not designed or constructed for travel by the larger vehicles that are in use today. Since its original construction, the Generals Highway has needed periodic repairs to address structural deficiencies and normal wear that have led to deterioration of the highway. However, in 1993, the design and reconstruction of the entire 28-mile Generals Highway began. Reconstruction was needed because the Generals Highway was in poor condition with several failures, had short sight distances, several drainage issues, and did not meet Federal Highway Administration (FHWA) design standards.

Now, workers are reconstructing the road to widen narrow sections, constructing new or rehabilitate existing retaining walls, improving drainage, constructing new pullouts, and making other improvements.

The intent of construction projects along the Generals Highway is to correct structural and drainage deficiencies that could lead to major road failure and that jeopardize the integrity of the road and safety of visitors. In addition, the improvements are intended to provide a pleasant driving experience, improve traffic flow, facilitate maintenance operations, and reduce maintenance costs.
