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.
After having done a fair amount of research into how roads in Southern California are tolled and how each agency handles the tolling itself, I decided it was time to add another page to the site. Seeing as how each agency uses FasTrak in a different way and that there are, at least for now, five different agencies, each with their own transponder, in the region, it was time to help clarify some things. Please use the link below to access the new page. I hope the new page helps explain the confusion that is FasTrak.
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.
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.
