Document Description
The CA Department of Transportation (Caltrans) is proposing this Permanent Restoration project located in Humboldt County on State Route (SR) 299. The purpose of this project is to restore the roadway to pre-storm damage conditions, reduce the risk of future damage, and improve resilience of the highway facility. This location has a history of recurring slope failures and associated damage, and future storm events are likely to contribute to the risk of roadway loss. The project scope proposes to stabilize the failed roadway segment by shifting the roadway centerline up-slope from its current position, constructing Soldier Pile Ground Anchor (SPGA) walls on the down-slope side and Soil Nail (SN) walls on the up-slope side.
