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.

Old Rialto Ave and Arrow Route in San Bernardino, CA

Sometimes when a road gets realigned, a portion of the old roadway remains as an access road. This was the case when a small section of Rialto Ave (Arrow Highway/Route) was realigned in 1961 between Rancho Ave and Mt Vernon Ave. This realignment left behind a short span from the 1940’s. The bridge doesn’t have a date stamp nor is it still in the county bridge logs, so an exact date is tougher to find. Still, this bridge has a fine example of bridge rail from that era and is a good find.

Old US 99 at Weldon Summit

US 99, known as “The Old Road” in the Santa Clarita area, has had a varied past. It was first built through this area in 1930 as a three-lane highway. This roadway, known then as the Newhall Alternate, would be the first of many versions of the road through this pass.

This is the last remaining uncovered stretch of the 1930 Newhall Alternate concrete. Motorcycle is on the 1951 alignment.

In 1949, the roadway was temporarily widened to four lanes by restriping and adding some paving to the shoulder. This was done as the real work to upgrade the highway wouldn’t commence for a couple of years. Evidence of this widening can still be seen today.

In 1951, US 99 was realigned and finally upgraded to an expressway, though this would not last long. Just south of this point, the highway was realigned again to accomodate a new freeway from the Tunnel Station Junction (US 6 and Foothill Blvd) to Sepulveda Junction (State Route 7). This freeway still exists today in part and serves as the “Truck Route” through the pass.

Starting in 1967 and ending in 1975, the pass was yet again the site of major construction. This time, little of the old highway would be utilized as the new route of Interstate 5 bypassed much of the existing route. Where it didn’t bypass the alignment, it was torn up and completely replaced with the current roadway.

US 99 would, however, serve as the main route one last time following the January 17, 1994 Reseda / Northridge earthquake. Portions of I-5 collapsed during the earthquake, resulting in a need for a quick replacement. The resulting detours created an alignment very similar to the pre-1967 highway, giving motorists (albeit not with joy) a chance to drive old US 99 again. Upgrades were made to the highway through the pass including repaving, guardrail, and a temporary prohibition on left turns. Sadly, for highway historians, this resulted in the loss of the 1951 concrete and some curbing. It is a price to pay to help keep California’s Backbone functioning during a crisis.

Ridge Route Centennial Celebration Coming Soon!

99_old_shield_big

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.
