- Origins of the Old Ridge Route - (Part 2)

While this was going on, The Automobile Club of Southern California had been campaigning for Good Roads. Southern California’s Good Roads campaign was called the most advanced "west of the Mississippi". They were actively working with the Los Angeles Chamber of Commerce to push for improvements. They had signed many routes and made maps to make travel safer.

But soon came the explosion of the automobile, and California had already been planning for it.
1908, the Model T was made widely available. This was the game changer in transportation. The automobile became a serious contender for the railroads and stagecoaches of the time.

After 14 years of the Auto Clubs campaigning, the 1909 California First Highway State Bond Act was passed. Bringing $18 Million of funding to construct the new State Highway System. With the intent of creating a “continuous and connected state highway system”. “No longer will counties be spoken of as being ‘remote or inaccessible”. They prioritized the most direct routes, with doable grades and good drainage.

The goal was to have passable, all weather routes, connecting a rapidly dividing state. This particular route being one of two “trunk roads” - the primary north-south. Sister roads, the Coastal Route and our, yet to be determined, Inland Route.

But could they agree on the path it would follow?

- Origins of the Old Ridge Route - (Part 1)

California is famous for it’s highways - both good and bad. We often just accept the way things are right now but don’t put much thought into how we got here.

So here’s where the story starts. 1895, the Bureau of Highways was created. They conduct a study with the question in mind - What do Californians need when it comes to highways? The Bureau recommends a whopping 4500 mile system. Keep in mind travel is still widely horse drawn or by train. By 1897, certain routes had been appointed as state routes. This one being the Stockton-Los Angeles Route, a rough and unpredictable stagecoach road. Often washed out, muddy, filled with ruts, with steep grades and severe weather. It made for unpredictable travel times. This range of mountains was effectively suffocating travel and trade for the state.

“The roads of California are in a deplorable condition. The absolutely system-less manner in which the majority of the roads in the State have been located and constructed, and are being maintained, as well as the extensive unnecessary mileage, are evident to any one who has traveled over the State” [Biennial Report of the Bureau of Highways (1895-1896)]

With all this disapproval of the current road system… what was being done?

Board meeting discussing potholes, future CUTRR dates and tours

SoCalGas has joined forces with the Ridge Route Preservation Organization to fill potholes on the 1915 Old Ridge Route. The 111 year old road runs between Castaic and Gorman and is the predecessor to the current day I-5 stretch, commonly refereed to as the Grapevine. This vital link, credited for uniting the state of California, sat largely unmaintained for decades. A group of dedicated volunteers has been working to save it.

Now, in April of 2026, SoCalGas is stepping up to help. Honoring a long time relationship between the pipelines and the road by filling potholes on nearly 12 miles of the Old Ridge Route.

Send a "thank you" to the road crew and find the full story here: https://ridgeroute.org/around-200-pothole-filled-on-the-old-ridge-route-by-socalgas/

Dead Man's Curve on the Old Ridge Route.

This curve was notorious for accidents, so much so that the ravine below was nicknamed "The Junkyard". Cars would often try to pass around the blind curve, go too fast and end up over the edge. Trucks would lose their brakes or miss the turn in bad weather.

The I-5 now cuts through this alignment but it can best be seen from Digier Road, near Fort Tejon.

Want to be a part of the restoration of the Old Ridge Route but live further away? Or maybe you're not able to physically do road work but still would like to support?

We're looking for a Secretary - could it be you?
"The Secretary shall be responsible for the records of the organization and shall keep or cause to be kept a book of minutes of all meetings of directors with the time and place of holding, whether regular or special, and if special, how authorized, the notice therefor given, the names of those present at the meeting of directors, the numbers present and the proceedings thereof."

Our board meetings happen once a month, held online so you can join from anywhere. You'll be the first to know about all things Ridge Route and have a say in the future of this old road.

Send us a message if you're interested in this volunteer position!

Super productive Clean Up the Ridge Route volunteer day today!

We had a FANTASTIC group! Filled 4 potholes, cleared dirt from 2 locations, filled a rut, fixed the falling Landslide Ahead sign, picked up the old plastic on the landslide, and cleared rocks from a curve. All before noon!

I can’t say enough how thankful I am to our volunteers and donors - you all make saving this old road possible

We purchase 7 bags of Quikrete Asphalt Repair to fill potholes and a bag of quick setting concrete for the sign. We have had quite a few donations lately that have made this possible!

Great day to be out doing roadwork in the Angeles National Forest too!

Stay tuned for our Summer CUTRR dates
