Ridge Route February 2024 Update Video

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.

Ridge Route Preservation Organization Begins Pothole Project

From the Ridge Route Preservation Organization:

The Ridge Route Preservation Organization was cleared by the Angeles National Forest to repair potholes along the north section of the Old Ridge Route from the 138 to the Tumble Inn.

The intent is to preserve the road and make it more accessible to the public as well as emergency services. Filling the potholes can reinforce crumbling sections of the road as well as prevent further damage to the original road surface.

The Ridge Route Pothole Project will begin in spring of 2024.

These improvements don’t only serve to protect the history of the Ridge Route, the repairs will also serve everyone who passes through the area. It’s a large stretch of open land that provides recreation for hikers, cyclists and hunters as well as being a heavy fire danger area. It’s important that emergency vehicles have quick and easy access when mere seconds matter.

A donation of $15 buys a 50 pound bag of asphalt cold patch.

Original pavement remaining at Castaic Junction, CA on old US 99

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.

A Brief History of the Roadway Changes

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.

Ridge Route Work Event – May 20, 2023

Event announcement from the Ridge Route Preservation Organization. Please go to their website to sign up and get additional information.

We are planning our first CUTRR – Clean Up The Ridge Route – event to be held on May 20, 2023. The road has suffered through a lot this winter and it needs your help! Our work will concentrate on clearing drains of debris on the northern end between the Tumble Inn and Reservoir Summit. Due to conditions, we won’t be able to go over the entire roadway afterward as we have done in the past. Additionally, lower clearance vehicles are not recommended on the Ridge Route at this time.

Please RSVP so we can get a rough headcount before the event. We look forward to seeing you all out there!
