The Old Ridge Route has suffered a landslide just north of the gate in Castaic. At 0.82 miles north of the gate, about a 25ft length of the roadbed has been compromised. This is on the west side of the road and about 5-6ft deep into the road surface.
The 2018 pavement still remains intact, though there is no foundation under it. It is not advised to drive the road, even if a gate is found open. It can be potentially dangerous as these landslides aren’t always obvious from the road surface. The weight of a car could cause collapse of the road surface, especially when the hillsides are saturated.
If you are traveling on foot or by bike, please be aware of the road under you. If an area looks to be sinking, avoid it. Keep clear of cliffs and steep edges.
If you are interested in road repair and clean up efforts, please subscribe to our mailing list. We will be sending out volunteer opportunities as the area dries up.

From one of our members – Sydney Croasmun:
There was a real problem with roadways washing out leading up to the construction of the 1915 Old Ridge Route. That ended up being the deciding factor for the placement of the road. When surveying locally, there were pre existing options that could have been used in place of the section we now know as the Ridge Route.
So why would they choose to essentially start from scratch instead of using a well known road as one of the first California highways?
One by one, the pre existing options were disqualified by Division VII Highway Engineer, W. Lewis Clark. San Francisquito Canyon was deemed “a steep, narrow, dangerous way that crosses a creek too often”. Soledad Canyon had a history of constant washouts. Bouquet Canyon, known at the time as “Deadman’s Canyon Road”, was disqualified on account of “sharp turns, steep pitches and threatening drainage problems; no way of joy”. Finally Mint Canyon was deemed excessive in length among other problems.
The Ridge Route was part of the Inland Route – one of two “Trunk Roads” running north and south through California. A sister road to Highway 1. It was of great importance that this road stay open and functional – rain or shine. With the existing roads disqualified, W. Lewis Clark set out with a few pack mules to find a new, suitable route.
The Ridge Route was a type of road new to America. Inspired by European engineers, they set out to build this new route on the tops of the mountains – when it was common practice to build in canyons. This avoided river and creek crossings and eliminated the need for bridges. Preventing many of the nasty washouts that happened regularly on canyon roads.
That’s why the Ridge Route was built along the ridges!
Road Conditions Update
The storms of December 2022 and January 2023 have hit the roadway hard. Damage is fairly widespread with mudslides and rockslides being the order of the day. Reports given to us by members and the public have shown sections to be impassible by a standard automobile in many locations. From the Tumble Inn to Sandberg, there are numerous areas with flooding, mud, and rockslides. A few larger slides have been noted near Swede’s Cut and Serpentine Drive as well. At this time, it is not known if further damage has occurred between the Tumble Inn site and Swede’s Cut. It does not appear that the roadway has suffered similar damage to that of 2005, which saw the loss of three major sections of roadway. Weather permitting, we will be conducting a survey of the roadway over the weekend of February 4. As this winter is not yet over, further damage may still occur, likely in the form of landslides. We are hoping none are catastrophic, but years of minimal maintenance are taking their toll. CUTRR events will be scheduled later this year after this winter and spring calm down. Right now, we have a few targets for work regarding clearing drainages to prevent or mitigate flooding and sedimentation on the roadway. Stay tuned to our CUTRR pages for updates on those events.
It is also imperative that no travel other than emergency or essential work be taken over the Ridge Route during this period. Permanent damage to the roadway can be done if care is not taken. Do not travel beyond the gates if they are open. Those gates are locked by default and you can get stuck!
Ridge Route Mapping Update
Our mapping project is in its final phase! The base map and basic features are nearly done. Photos and additional information are being added at this time. Once it is available, we will make an announcement on the site where it can be viewed.

The Route Fire burned a section of the Ridge Route (hence the name) from Callahan’s to just south of Templin Highway. Thankfully, the fire didn’t destroy the last remaining Ridge Route structure, Martin’s Garage. It did expose quite a few sections of the roadway that were bypassed and buried long ago. This section, just above Martin’s, is nearly completely buried by debris. Only patches of paving and a lone c-monument remain visible today. Scenes like this could be commonplace should a fire strike the rest of the roadway, something we very much want to avoid.

It has been a while since our last update. I’ve been busy with a move and house remodeling, which has taken me away from things. Unfortunately, we don’t have a lot to report. We are still working with the USFS to get the roadway open and develop a management plan for the roadway.
Over the weekend of August 20, I was able to take a trip over the Ridge Route to survey the roadway. For the most part, there was good news. The roadway is still in pretty good shape. Earlier this year, utility crews cleared large portions of the road from Serpentine Drive to near Sandberg. That work has helped to keep the roadway in better shape over the summer and hopefully into the coming winter. Only small rockslides were found at Swede’s Cut and below Reservoir Summit on the north side of the summit.

In early August, a small fire occurred at the north end of the Ridge Route where it meets State 138. The fire, known as the Sam Fire, was held at 150 acres and didn’t cause any damage to the Ridge Route. It did burn along State 138 from the Ridge Route to the California Aqueduct and partially up Bald Mountain. An additional fire started on August 31, known as the Route Fire, near the southern end of the Ridge Route along northbound I-5. It is not known at this time if the Ridge Route is affected though it has progressed to the Callahan Line Change site as of 1600 on August 31.
The roadway is still closed at this time even though there have been reports of the gates being left open. Keep in mind, the gates can be closed and locked behind you, so please do not travel beyond them by motor vehicle. Travel is still allowed via walking, horseback, and bicycling.

With all the recent fire activity as well as other events such as January 26 when big rigs tried to travel the Ridge Route, we thought it was a good idea to have a place to report things. If you see something wrong on the Ridge Route, be it a developing washout, large vehicles traversing the roadway, or things out-of-the-ordinary, we have have set up a web page to help you report things on the road. We will pass the information along to the appropriate agencies as needed.
To Report Problems or other issues on the Ridge Route, please use the website below. The web page is also located under our “Current Roadway Conditions” page in the menu.

This month’s photo comes to us from Caltrans and shows the town of Gorman as it was in 1958. The Ridge Route proper can be seen in the distance to the right. In the foreground near the bottom of the photo, a short section of original 1917 paving can be seen as a small diagonal roadway ending near the Gorman Motel site. This was realigned in June 1933 when the Ridge Route Alternate was under construction. While gated, the roadway remains today and can still be seen off of Gorman Post Road just south of Gorman School Road.
Another wildfire has started at the south end of the Ridge Route in Marple Canyon along the 5. This fire, known as the Route Fire, has so far burned 250 acres and is not contained. The fire has burned across the old Ridge Route at the Callahan Line Change location, about 2 miles north of Castaic. Evacuations are underway as far north as Templin Highway. The fire has burned as far north as Martin’s, south of Templin Highway. It is not known if the structure survived.
At this time, I-5 is closed from State 138 to Castaic. The Ridge Route is also closed to through travel from Castaic to State 138 as the gates are closed. Do not use any portion of the Ridge Route as a bypass for I-5 at any time as it is not built for heavy traffic. Big rigs have attempted this in the past and got stuck, blocking others in.
For further information regarding road closures and detours, we strongly recommend Caltrans Quickmap at https://quickmap.dot.ca.gov/ which has detailed information and updated traffic conditions.
We will post updates, as needed, if the Ridge Route itself or historic structures are damaged or in danger. After the fire is out and things have settled down, we will assess any damage to the roadway and post a report.
There was a fire today at the north end of the Ridge Route. It burned along State 138 south of Quail Lake to the Ridge Route. So far, it seems to be contained at around 150 acres and hasn’t affected any historical features along the roadway. State 138 was closed through the area between Gorman Post Road and 170th St West. The Ridge Route is closed from State 138 to at least Pine Canyon Road at this time. Further details will be posted if more develop.
