BUTTE COUNTY, Calif. – Caltrans is alerting motorists that State Route 70 will remain closed through the upcoming storm this weekend.

The estimated time of reopening will be determined after the storm evaluation is completed. Caltrans aims to reopen the road to one-way traffic control by mid-week.

The closure will extend from Jarbo Gap to the Greenville Wye in Plumas County.

Neil’s Controlled Blasting, in collaboration with Caltrans' Geotechnical engineers, is actively scaling the mountainside along SR-70. Caltrans assures motorists that safety remains paramount during these operations.

Conducted by Caltrans geologists, a thorough assessment of the slope's stability has highlighted the critical need for a full closure, prioritizing safety.

Spanning an area of 100-150 yards, encompassing the mountainside along the canyon, these rock-scaling efforts are essential to limit more slides. Every endeavor is directed toward maintaining the highest standards of safety, Caltrans said.

Motorists are encouraged to check Caltrans’ QuickMap before traveling for current road conditions and chain requirements or download the QuickMap app from the App Store or Google Play.

Road information is also available on Caltrans’ website or by calling the California Highway Information Network automated phone service at 1-800-427-ROAD (7623).
