In early and mid-February 2024, the Ridge Route Preservation Organization went on a field survey trip over the Ridge Route to assess damage. They took a lot of videos and put together an overview of what they saw.
Come join the Ridge Route Preservation Organization on their journey over the Ridge Route.
Castaic Junction, located just north of Six Flags Magic Mountain in the Santa Clarita Valley was an important stop along US 99 and State 126 until the 1980’s. A Standard Oil gas station, one of the largest and busiest at the time, was located here in addition to Tip’s Restaurant. The restaurant was reported to be the last stop for James Dean before he died on September 30, 1955. A Beacon station also existed here at the south side of the junction, though it didn’t last as long as the Standard station. The gas station closed sometime in the 1980’s and the restaurant persisted as the Castaic Junction restaurant a bit longer.
The roadway through the junction has also undergone many changes since it was first paved. In 1917, a 15′ concrete slab was laid down. This was widened in 1922 by adding two 2.5′ slabs on either side of the existing concrete. At the time, Castaic Junction was a “wye” intersection, with US 99 making up the east side and State 126 on the south side. The west side was a connector road from SB US 99 to WB 126. In 1931, the 1917/1922 pavement was removed and replaced with a wider two-lane section along the same route. By 1933, an additional lane was added making it a three-lane “suicide lane” setup.
In 1948, yet more changes were made to the junction. US 99 was realigned a bit to the east and made a four-lane expressway. State 126 was also widened, though just at the junction itself. The former west leg of the junction was removed as the Standard Oil gas station was augmented. This configuration lasted until 1964 when I-5 was constructed and the whole intersection was bypassed.
Today, little remains of any of the structures that existed at the junction. A new shopping center and Caltrans maintenance yard occupy the area east of the junction. The original traffic signals were replaced and additional curbs were added.
Surprisingly, the original 1917 wye junction remains nearly completely intact. The west and east legs of the junction are still visible, despite a major realignment, the construction of the Standard Oil gas station in 1948, and its subsequent demolition. How long any of this will last is unknown as development is likely to erase these traces in the near future.

From the Ridge Route Preservation Organization:
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.
On September 13, 2022, I will be giving a Zoom presentation for the Historic Highway 99 Association of California on the Ridge Route Alternate between Castaic and Tejon Pass. Come join the Association for the presentation! See the link below for details and to learn how to sign up.
