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.

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.

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!

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.

Website Updates

Over the past week or so, I’ve been working to add more content to the site. Not to avoid completing the existing pages either, just to fill in some gaps. Here are some of the updates:

  • New Website Feature – a new Discussion Forums feature has been added. It is an experiment, so we’ll see where it goes.
  • New SectionCivic Information – These pages give links to every incorporated city in Southern California and give a bit of information about each county as well. The links are finished, but the format is still being worked on.
  • New PageSeeking¬†Old Highways – A while back I was working on putting up a guide to looking for old roads, bridges, and signs. It is still a work-in-progress, but has now been more given its own page in the Highways section.
  • Additional Historic Photos – Old photos of US 101 in the Los Angeles area have been added to the US 101¬†page.
