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.
A new bypass highway was completed a couple years ago by Caltrans around Brawley. Signed as State 78 and State 111, it forms a northeast loop around town. It is an expressway, not a freeway. This distinction makes for some unusual signage where there is an interchange with State 111.



I took a trip recently to the Corona area to check out some of the old alignments of US 91. I had been there before, but it has been a long time. Starting from the Green River exit off of the 91 Freeway, I headed east along the south side of the freeway. Here, the roadways named Green River Road and Palisades Drive cover the pre-freeway alignment of US 91. This section is also a portion of the 1939 Prado Dam Relocation. This realignment took the highway out of the riverbed to the north and pushed it closer to the hills. A significant portion remains today relatively intact.
Near the Green River Road interchange, an abandoned portion of the roadbed is revealed by a 1939 culvert. The pavement has long since been removed. A portion of the old median, complete with curb divots, remains to the east. The best portion, however, is on Palisades Drive. This section has a fairly continuous old median, old bridges, wooden railing, and even a mile marker from Route 91. This whole section was bypassed in the early 1970’s along with a change to the 91 / 71 interchange.
