US 6 – Santa Clara River Bridge – A Closer Look

US Highway 6, now known as Sierra Highway, crossed the Santa Clara River near Solemint, California. The bridge it originally used, constructed in 1938, is planned to be replaced in the near future. This bridge is one of the oldest remaining in the Santa Clarita area and is the longest span on former US 6 in California. The bridge has remained almost intact from its original construction. The only changes have been minor to the bridge itself. The highway, however, has changed quite a bit. In 1968, Sierra Highway, then State Route 14, was widened to four lanes. A second bridge for northbound traffic was added, with the original bridge being used for southbound traffic.

Presently, Sierra Highway is six lanes wide at the river crossing. As the bridges were built with a four-lane highway in mind, only a narrow shoulder along both directions exists. This condition is one of the reasons the bridges across the Santa Clara River are being replaced.

In March of 2017, I took a trip to inspect in more detail the bridge and the surrounding area. It was nice to see the bridge again, as it brought back a lot of memories. I used to live near the bridge and crossed it almost daily. It will be sad to see it go as it is one of the last remaining pieces of the old highway. So, please, check it out yourself while you still can. I’m not quite sure when the construction will begin, it may have already.

Los Angeles County Survey Records

Los Angeles County Department of Public Works has a wealth of information available on their website. With a bit of patience and some looking around, you can find quite a few treasures using their mapping application. I’ve so far found the original survey data for the “Bridge To Nowhere” roadway, plans for other roadways that were never built in the Sierra Pelona Mountains, as well as the forest service permit for the Shoemaker Canyon Road that was never completed.

Wigwags – Part 4

When you did deep enough and look hard enough, you’ll find there is far more history left in Southern California than you might think. I have found this to be true when it comes to finding wigwags in the region. This one, in Hawthorne, CA, is along a former Pacific Electric Railway line that headed to Manhattan Beach. Located at Eucalyptus Ave just north of El Segundo Blvd, it still presses on as a lasting tribute to the old railway, now a part of the Union Pacific Railroad.

New Ridge Route Video, sort of

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 near Liebre Summit. It shows some of the issues the road is facing presently regarding erosion and a lack of maintenance.

Ridge Route Online Petition

Hello all,

The Ridge Route in Southern California needs your help. The Ridge Route Preservation Organization has put together an online petition to help get the roadway back open and in working order. It has not been fully open to traffic since 2005 and is in need of your support. Please sign this petition to get the legislators and the Angeles National Forest to fix what they did wrong. More details are on the site for the petition.

Thank you for your time and efforts!

Wigwags – Part 3

Wigwags, or properly Magnetic Flagman, are a rare sight in Southern California. Recently, I found two more located in Gardena, CA along a former Pacific Electric freight spur. Today, the Union Pacific Railroad operates this stretch to service a lumber yard
at Western Ave. Both of these wigwags are just southeast of the intersection of Western Ave and 166th St.

US 99 in Alhambra, CA

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.
