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.
