On August 12, 2017, I will be hosting this websites first highway tour in the Cajon Pass area. This tour will cover the roadway from Verdemont to Cajon Summit. Some portions will have to be skipped, unfortunately, due to fire-related closures. The start of the tour has changed from the initial announcement. It will now begin at Devore, in front of Tony’s Diner at 18291 Cajon Blvd, San Bernardino, CA 92407 at 8 am. Please do not park in their parking lot. There is plenty of on-street and off-street parking in the area.

After a brief introduction, we plan to leave at about 8:30 am. The tour will stop at the following locations:

  • Verdemont (backtrack)
  • Cajon Blvd (at the freeway)
  • Kenwood Ave
  • Keenbrook
  • Blue Cut
  • Debris Cone Creek
  • Cajon Junction
  • Cajon Summit

Additional stops may be added if needed. I strongly recommend bringing water and snacks as there are few water/food stops along the route. Please RSVP if you plan to attend this tour. Again, we will be leaving the starting point no later than 8:30 am. Please RSVP no later than August 11 so that I can get a rough number of how many will attend. I look forward to seeing you out there!

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.

FasTrak and Express Lane Information

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.

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.

US 6 Tour goes east!

It has been a while since I’ve added to my US 6 tour. For quite some time, it “only” went to Tonopah, Nevada. While that town makes for a good end point, it left quite a bit of very interesting and scenic highway out of the tour. US 6 across Nevada is one of the emptiest highways in the lower 48 states. It gives travelers and geologists alike a very good cross section of the Great Basin as well as a look at the mining past of Nevada. With that in mind, my US 6 tour now extends to the Utah / Nevada State Line, covering approximately 620 miles of roadway.

Take your time and enjoy the tour!
