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.

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.

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 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.

Caltrans Adopt-A-Highway

This month marks 16 years for me as an Adopt-A-Highway program volunteer. In August 1998, I adopted a section of Interstate 5 in Grapevine Canyon in Kern County. To be more specific, my section is on Route 5 between Postmiles 6 and 8 in Kern County. I chose that section initially as it allowed me to inspect sections of old US 99 that I couldn’t reach before. Now that I have adopted it and have a permit, I can stop along that segment and see the old roadway.


I found that the section I adopted was also quite scenic and special. Of all the sections of Grapevine Canyon, mine has the most of the wild grapes that gave the canyon its name. It also contains one of the more famous sections of the original Grapevine Grade, Deadmans Curve. During wildflower season, the canyon is green and alive with yellow, orange, and purple flowers. Deer, hawks, and other wildlife can be spotted in the canyon as well.

Passing through Grapevine Canyon now gives me a sense of pride. I’ve actually gone there many times to help clean the highway, given stranded motorists help, and fixed things along the roadway. It is something that I enjoy doing and something that I don’t do often enough. When I first adopted it, I lived in Santa Clarita. Now I live in San Diego, much further away. As a result, I don’t clean it as often but still try to get up there as much as I can. I’ve also had the help of friends at times which has been nice.

I encourage all those that have the ability to adopt a roadway to do so. You can help clean up some of your community, or even someone else’s in my case. You can help others and can be a lot of fun. Most counties and states have this sort of program. Find out what your local agency has and find a section to adopt. You never know what you might find out there.
