Blue Cut Fire and Other Wildfire Information

With all the wildfires propping up lately, it is important to stay on top of the news. Your local newspaper and tv stations should be able to give updated information, but you can also get it directly from the agencies involved. I highly recommend the sites listed below as they can give more detailed information about what is going on and are usually updated regularly.

Blue Cut Fire

Fire Perimeter Map from InciWeb as of 8/17/2016 at 8:22 am

In regards to the current fires in the Cajon Pass, I plan to assess the damage to the highways myself once the area is clear. From what I understand so far, it looks like most of the wooden railing along US 66 / 91 / 395 in the pass may be gone, in addition to the historic Summit Inn restaurant at Cajon Summit. Other structures, not associated with the roadway, have also burned. According to CHP, a railroad bridge in the pass has burned, the Alray UP where former US 66 / 91 / 395 passed below. Please stay clear of the Cajon Pass for the duration of this fire.

DETOURS:

If you need to head north toward I-15 and I-40 near Barstow, I recommend taking I-10 East to State 62 East to State 247 North to Barstow. From there, you will connect with I-15 and I-40 just west of their junction. State 247 is a two lane roadway and may be busier than usual, so use caution.

All other traffic should use State 14 through Santa Clarita and the Antelope Valley to connect with points to the north/west of I-15.

Following old US 91 near Corona

I took a trip recently to the Corona area to check out some of the old alignments of US 91. I had been there before, but it has been a long time. Starting from the Green River exit off of the 91 Freeway, I headed east along the south side of the freeway. Here, the roadways named Green River Road and Palisades Drive cover the pre-freeway alignment of US 91. This section is also a portion of the 1939 Prado Dam Relocation. This realignment took the highway out of the riverbed to the north and pushed it closer to the hills. A significant portion remains today relatively intact.

Near the Green River Road interchange, an abandoned portion of the roadbed is revealed by a 1939 culvert. The pavement has long since been removed. A portion of the old median, complete with curb divots, remains to the east. The best portion, however, is on Palisades Drive. This section has a fairly continuous old median, old bridges, wooden railing, and even a mile marker from Route 91. This whole section was bypassed in the early 1970’s along with a change to the 91 / 71 interchange.
