After finally resolving some software issues, I have finally been able to start editing and posting videos again. My most recent one was taken in November 2015 along the Ridge Route from the Tumble Inn to State 138 at Neenach. It shows some of the issues the road is facing presently regarding erosion and a lack of maintenance.
Bridges and culverts can be great indicators of when a highway was built and by whom it was built. In California, there are a few different styles of railing which can be used to put a relative date on a particular bridge when they don’t have date stamps on them. Other indicators may be used when the bridge rail has been modified or even replaced by modern rail. Styling elements on the superstructure vary depending on age. Older bridges tend to be more ornate than more modern structures. This page will serve as a guide to these styles and help to increase understanding of what goes into the design of these bridges.
San Diego’s Mission Valley can be quite a challenge during the winter. Most of the crossings of the San Diego River are low and not bridged. As a result, when it rains these crossings can be closed rather quickly. This greatly affects the ability to transect the valley along these roadways. The freeways, I-5, State 163, I-805, and I-15 are built with bridges and high enough to not flood. This is a guide to what is normally closed during storms.
From west to east:
Pacific Highway – Bridge – not closed
Morena Blvd – Bridge – not closed
Fashion Valley Road – closed more often than not during storms. This crossing has been rebuilt several times as well.
Avenida Del Rio – closed regularly during storms.
Mission Center Road – low crossing built a little higher than average. Still floods during major storms but is strong enough to avoid being damaged as a result.
Camino Del Este – Still low but built strong. Closes during major storms.
Qualcomm Way – Closes during very large storms. Built a little higher to help keep it open during major storms.
Ward Road – very low crossing and subject to closure during storms.
San Diego Mission Road – low crossing and subject to closure.
Friars Road (east) – Bridge – does not close.
Now, in the event all of these low-level crossings are closed, it is probably best to simply avoid Mission Valley in general. If you have to be there, I would suggest taking the 163 or 15 to cross the San Diego River. It may be a convoluted and circuitous route to use, but it is your only choice. Mission Valley circulation wasn’t designed with the river to flood in mind, unfortunately. Some developments, such as Fashion Valley Mall, was at least partly designed for flooding. The southern parking structure was built with the lower floor to be flooded and still allow for use of the rest of the structure. Even MTS built the San Diego Trolley Green Line with the floods in mind. Most of it is elevated through the valley.
On September 6, 2016, I finally got a chance to survey the damage to the roadways in Cajon Pass that were involved in the Blue Cut Fire. Portions of the area are still closed, specifically the area north of Cajon Junction, so I was unable to access the Alray UP or the abandoned expressway sections in that area.
I was, however, able to inspect State 138 east of I-15 and all of old US 66 / 91 / 395 south of Cajon Junction. I chose not to investigate State 138 west of I-15 as there was a lot of heavy construction in progress for a four-lane widening project.
I started my journey by taking the “new” Cajon Blvd alignment that bypasses Devore Junction (I-15 and I-215). Caltrans has recently completed reconstruction of this interchange and as part of that reconstruction, they have partly rebuilt Cajon Blvd through here. While much of it is a new alignment, it does follow the original alignment (pre-1937). As a result, I was able to get some nice photos of part of that alignment.
The burn area itself became very apparent after Kenwood Road. The fire in this area burned as far as Keenbrook, damaging many structures in that area. A few things didn’t get burned though. One, a lone sign that says “EAT” along with its accompanying structure, remained intact. At Blue Cut, the source of the fire, I was rather amazed at what didn’t burn. Most of the cottonwood and oak trees survived untouched as well as most of the guardrail in the median of the expressway.
North of Blue Cut, the burn area stops mostly at the old highway, but not east of it. The wooden railing is still intact at Debris Cone Creek. Some structures were damaged near Cajon Junction, such as the Chevron gas station and the McDonalds restaurant.
After Cajon Junction, I followed State 138 east toward Summit. The burn area covered the entire highway from Cajon Junction to Summit Valley Road. This section is scheduled to be realigned in the near future as well.
Overall, most of the old highways through the Cajon Pass remained intact. Some guardrail was damaged but most was only lightly burned. How this area will react during the next few major rain storms does remain to be seen. Hopefully, mudslides and debris flows don’t become the order of the day.
All these were taken on July 1, 2016.
While much of the 1934 Garvey “Superhighway”, former US 60 / US 70 / US 99, has been either built over or completely modified, a small portion remains virtually untouched. In Alhambra, CA, there is a small section of original concrete paving still intact. This section, called Garvey Ave, runs from Ramona Rd to Casuda Canyon Rd.
At Fremont Ave and Monterey Pass Rd, there are also some grade separations from 1934 that are still intact. These weren’t photographed but videos were made. When I get my video software working again, I will post those.
