     Canyon Creek Road Slide  Extension 8 on  DOT phone 530-623-1365 for road event updates

Dyer update for Canyon Creek Rd March 20 through April 1 2023



 Trinity County Road Crews will  be able to maintain the road above the Canyon Creek Slide when Dyer Excavation allows safe through travel.

If a large amount of debris blocks the road, it could take days, weeks or even months to clear the road enough for traffic to pass.  This County has NO CONTROL over this.   

We strongly advise that residents consider the high risk that they could be trapped for extended periods of time with no way in or out, and no access for emergency vehicles, and decide whether they need to relocate until the slide is stabilized.


For questions regarding the Canyon Creek slide project, please contact Kandace Claybaker project manager with Dyer All Terrain at (727) 417-7766. The DOT will post other updates as they are provided to us from the contractor.


Dyer plans to work on Saturdays, again this will be weather dependent.


Trinity County DOT will be provided with WEEKLY updates of traffic control measures to be implemented by Dyer All Terrain Excavation.  These traffic schedule updates will be provided every Friday for the following week.  DOT will post these updates on our Facebook page and DOT website as soon as we are able in order to help assure that residents and interested parties are informed of any weekly traffic control measures. We suggest following either of these two sources for the most up-to-date information available.

During the time Dyer Corp. is under contract, they will determine the required traffic control measures for the site based on safety considerations and work requirements. 

County Crews will (winter) maintain the road as we are able and as allowable based on Dyer Corp. traffic control restrictions.

While the responsibility of wildlife animals rest with the United States Forest Service or California Department of Fish and Game, they do not pick up wild animal carcasses. At this time there is no public agency in Trinity County that removes animals struck by vehicles. 


If an animal is struck by a vehicle and obstructing a County Roadway, the D.O.T. road crews may move the animal to the side of road, but will not remove the carcass from the site.


If the animal dies on private property, it is the owner’s responsibility to dispose of the carcass; State Highways are handled by Caltrans. In the case of a domestic animal, please call the Trinity County Animal Shelter (530-623-1370); they will attempt to locate the owner but they do not pick up the animal – that is the owner’s responsibility.
