Original paving in Grapevine Canyon

This is a section of abandoned roadway, paved in 1919, within Grapevine Canyon, near PM 8.0 on the east side of the canyon. This section was bypassed in 1933 by a newer alignment of US 99.

Fire in Grapevine Canyon, Kern County

It would seem that both ends of the Central Valley are having issues. Yesterday, a fire broke out along I-5 in Grapevine Canyon, known by Kern County Fire as the Water Fire, most likely named as it was near one of the watering holes along the grade. The cause may have been a truck fire which spread to vegetation. From photos and videos, it looks like the fire burned along the southbound side from near PM 7.0 to 7.5. This happens to by along my cleanup section. I will be doing a thorough investigation when time allows, most likely in October. This section includes a two sections with original wooden railing, albeit damaged from previous fires in the canyon. I will post photos on my Twitter account as well as this site when I get them.

For now, see the Kern County Fire twitter account for current details.

Be safe out there and really be careful around the brush. Too many fires are being caused by carelessness, nevermind the fires that have been the result of arson.

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.

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.
