Adopt-A-Highway Cleanup – May 20, 2017

On May 20, 2017, I am planning a cleanup of my section on I-5 in Grapevine Canyon. Specifically, this is KER-005-6.0/8.0. For those interested in joining, please send us a message to add your name to the list. The plan, thus far, is to meet in Lebec in the morning and carpool to the cleanup site to reduce the number of vehicles along the roadway. Let us know as soon as possible if you are interested in joining us. A partial tour of the remaining sections of US 99 and the Ridge Route in Grapevine Canyon, including Deadman’s Curve, will also be included in the cleanup.

Website Updates

Time for a website update!

The first “major” update is an extension of my US 99 tour. I’ve decided to take it north of the Kern River. How far north I have not yet decided, but so far at least as far as Delano to the Tulare County Line. I may push it to Goshen, but we shall see. More photos are necessary as well as more research. Maybe Fresno is in the future, but it will be quite some time away. Right now, I’ve extended the tour two stops north to the Oildale OH, the northern end of the 1933 Bakersfield Bypass.

Storm Damage Updates – Tejon Pass Area

This weekend, I had the opportunity to survey the damage from the recent storms in the Tejon Pass / Grapevine area. I took my motorcycle, as I expected to need extra clearance on some of the roadways I was going to take. The results of the survey were better than expected, mostly.

Ridge Route:

While I was only able to inspect the Ridge Route from State 138 south to the Tumble Inn, I was pleased to see how little damage was done to the roadway. As it has also been a while since I have been able to travel this section, I had to go by what I had heard and knew of the pre-existing damage. The bulk of the roadway was seemingly untouched by the recent storms. Only two sections, one with an existing problem, were a problem. One of those sections in particular, just south of Liebre Summit, is nearly impassable by a standard clearance automobile.

Grapevine Canyon:

Mudslides, due to a locally heavy rainfall, closed Interstate 5 through this canyon for some time. Mudslide damage is still very apparent from near Ft Tejon north to near the lower escape ramp. Most of the slides affected the northbound lanes. These slides buried a significant section of former US 99 paving, especially between PM 5.5 and 6.0. While a more detailed inspection will be done later, it appeared that most of the exposed Ridge Route concrete along the northbound side was intact, with the later US 99 concrete being buried. The southbound lanes were also hit, though most of the old highway sections were still intact and relatively untouched.

Overall, the damage from these storms was very localized. As we approach a possibly strong El Nino winter, it is my hope that this storm was not a preview of things to come. As this winter progresses, this site will try to document the changes to our historic roadways throughout Southern California.

Ridge Route and US 99 Update Coming

This weekend, I am travelling to the Liebre Mountains to inspect the damage from the recent storms on the Ridge Route, Grapevine Canyon, and the Ridge Route Alternate. I plan to inspect in detail those sections and take lots of photos. Updates on the status of the roadway will be initially via my Twitter account (@SocalRegionWeb) with a post update following. The sections I plan to cover in detail are Palomas Canyon (Five Mile Grade), Three Mile Grade, Ridge Route from State 138 to the Tumble Inn, Tejon Pass, and Grapevine Canyon. I’ll be taking my 2014 Kawasaki KLR 650 which will allow me access to more of the highway. Stay tuned for updates.

Ridge Route Centennial Celebration Coming Soon!


This year, the Ridge Route will be celebrating its 100 year anniversary. While the roadway is still not fully open to travel and has not been since January 2005, it is still there and still coming up to its century mark. This celebration will be held in Lebec at the El Tejon School, located near the top of Grapevine Grade on Lebec Road. For more information, please contact the Ridge Route Communities Museum. The road also needs your help and pressure to reopen the roadway to the public. For more information about this issue, contact the Ridge Route website.

From the Ridge Route Communities website:

Southern California – Defined?

This website started off covering a small area, the Santa Clarita Valley. I later started a second website for the San Diego area. Both sites were somewhat limited in scope. Now, with those sites combined, I’ve also increased the area that the website covers. The new name for the site, Southern California Regional Rocks and Roads seems to state a much larger area. What really is Southern California and what does part of it does this website really cover?

The region, Southern California, or So Cal by some, varies by definition. My definition isn’t exactly a standard one either but I think it is the best fitting one. Southern California is usually defined as the whole of Ventura, Los Angeles, Orange, San Bernardino, western Riverside, and San Diego Counties. This constitutes much of the populated section as well as the area west (or south) of major mountain ranges. This definition leaves out quite a large area, however. It really should be “Coastal Southern California”. How do I then define Southern California and what area I plan to cover with this website? I personally define Southern California as the area south of the 119 degree line, which tends to define the northern boundaries of San Luis Obispo, Kern, and San Bernardino Counties. This site, however, will cover a smaller portion of that region. This website will cover, eventually, the region encompassing all of Santa Barbara, Ventura, Los Angeles, southern Kern, San Bernardino, Riverside, Orange, Imperial, and San Diego Counties.

I’ve sometimes termed this website to be a “monster”. Why do I? Every time I think it is “done”, I come up with more projects to expand the site. There is a lot to cover here in Southern California and I intend to do the best job that I can for the scope of the site. Defining those boundaries will help to at least partially limit the site’s growth.
