Motorists should anticipate delays, one-way traffic controls as PG&E undergrounds power lines along highways 89 and 70 and in Greenville

Pacific Gas and Electric Company is resuming work to underground power lines in Plumas County. Contractors for PG&E are doing most of the work, which involves trenching in and alongside roadways.

Burying powerlines is the most effective solution to reducing the risk of wildfire from electrical equipment, reducing the risk of ignitions in areas at the highest risk of wildfire by nearly 98 percent. Undergrounding also makes power more reliable by reducing outages caused by winter storms, and in some cases eliminates the need for safety shutoffs.

“We at PG&E are deeply committed to doing everything we can to prevent wildfires in the communities we serve and live in,” said Joe Wilson, Vice President of PG&E’s North Valley and Sierra Region. “Our region has been devastated by wildfires in recent years. Undergrounding work protects our communities.”

One-way traffic controls will occur 24 hours a day at project sites as crews trench and install conduit for underground lines. Motorists are advised to allow for more time when traveling these routes and can expect delays of about 15 minutes at locations on Highway 89 and up to 30 minutes at locations on Highway 70 except for holidays, until the projects are completed in 2025.

PG&E is building and expanding its electric system underground to not only help reduce wildfires caused by equipment, but also to reduce the need for wildfire safety-related power outages. Undergrounding also will improve system reliability and decrease the need for as much vegetation management work.

The work is part of PG&E’s Community Wildfire Safety Program and is in response to California’s growing wildfire risk. Undergrounding is just one of our layers of wildfire protection that has proven to be effective in reducing wildfire risk.

PG&E is committed to moving 10,000 miles of powerlines underground in the highest fire-risk areas to reduce wildfire risk and improve reliability throughout California. Burying powerlines is the most effective solution to reducing the risk of wildfire from electrical equipment.
