ROAD CLOSURE NOTICE
The Ridge Route is CLOSED to through travel between Templin Highway and State Route 138.
The historic Ridge Route is not open for through travel between Castaic and State Route 138.
Important: Roadway conditions and access restrictions may change. Check with the responsible agencies before traveling.
It is open from only from State 138 to the Tumble Inn at the north end, and from approximately one mile north of Templin Highway to Castaic at the south end. The central portion remains closed to all motor vehicle traffic including motorcycles and off-highway vehicles. Walking, bicycling, and horseback riding are allowed. The roadway is not open for through travel from State 138 to Castaic.
There is currently a landslide impacting the road 1.8 miles north of the Castaic gate. We have been tracking it over the last year and it is still actively sliding. Repair efforts have not begun yet and this section is highly susceptible to slip during rain or snow.
Use caution on the northern end between Sandberg and Liebre Maintenance Camp site as there are many rockslides and other debris covering the roadway. Due to storms in December 2022 and January 2023, the roadway is not passable by a standard clearance auto for its entire length from Templin Highway to Sandberg. There is an active landslide near the south end and two locations where the roadway is undermined.
If you find the gate open at either end, do not expect the other gate to be open. The default position of the gate is closed at this time. Travel ONLY at your own risk as the roadway is legally closed. The gates MAY close behind you at ANY TIME.
