The first section of the San Diego Freeway in San Diego (US 101 at the time) to be constructed was the Mission Bay Bypass in 1954. Elements of this construction can still be seen today, such as some older curbing at the intersection of Damon Ave and Santa Fe St. North and south of this small section of freeway, it was still a narrower four-lane roadway with some expressway sections. Between 1966 (north) and 1969 (south), the adjacent sections were constructed, completing I-5 in the City of San Diego.

US 99 Tour Extension

It has taken a while, but I have finally extended my Virtual Tour of US 99, again. This extension adds another 40 miles to the tour, bringing the northern terminus to just south of Tulare, California. A friend of mine helped getting some of the photos as well. In time, I will extend the tour yet further to Fresno, but it will take a while as I am missing photos at this time. If anyone is willing to help, let me know and I can tell you what I will need.

So why not take a tour of one of California’s more historic roadways?

A friend of mine has been posting some really good videos on roadways throughout Southern California and Arizona. I highly recommend them as they offer an opportunity to travel some of the roads without leaving the comfort of your home during this time. Roads such as US 66 across the Mojave Desert, I-10 from Los Angeles to Phoenix, I-8 across the Imperial Valley, and more are covered. Check it out!

Views From The Ridge Route

2 Comments

In December 2019 and January 2020, I had the chance to take a couple of trips over the Ridge Route. Once this current situation is over, I fully intend to get back up there for a multitude of reasons. As I cannot get up there at present and we’re all still on some form of “lockdown”, I thought I’d share some of the photos I took up there. The Ridge Route is a very scenic route, far more than I-5 or even the “new” alignment of US 99. They all have their merits but the Ridge Route gets the best of the views. Just an FYI, some of these pics may be from earlier trips. Maybe you be the judge? Which is your favorite?

Care to help preserve the road? Head on over to the Ridge Route Preservation Organization to see what you can do to help and perhaps have the opportunity to traverse the Scenic and Historic Ridge Route.

Step faulting, slickensides, and heavily fractured rock

The San Gabriel Mountains have been subject to quite a bit of deformation in their past. Some of which is still ongoing, such as the movements along the Sierra Madre and San Andreas Faults. Here, near Mt Wilson, the rocks exhibit multiple instances of deformation. The white vein is mostly composed of quartz, which has been offset by multiple faults. Slickensides can be seen as the reddish areas on the right side of the photo. The surrounding materials are complex metamorphic rocks.
