A huge piece of California's Highway 1 was washed out this week by a winter storm that brought heavy rain and snow.

California Department of Transportation (Caltrans) officials said in a statement Friday a debris flow from the hillside above the roadway "overwhelmed drainage infrastructure, flowed across the highway, and eroded the road resulting in the complete loss of a segment of Highway 1" at Rat Creek, about 15 miles south of Big Sur, a mountainous stretch of the state's central coast.
California Highway Patrol Officer John Yerace said he was in the area on Thursday around 4 p.m. when he noticed "this section of roadway, specifically the southbound lane, had fallen off into the ocean."
Images and drone footage from the scene show a huge gap in the scenic highway, which runs along much of the California coast.

Seriously though, this is what, the 2nd or 3rd in the last year? I've always dreamed of taking a month and just drive one end to the other, but I think that is unlikely to ever happen. I am old, and between climate change and the normal process of nature winning in the end...
I hope no one was hurt ...

(9,760 posts)Not giving up on it yet, but even w/o climate change, there was always the high potential for earthquake factor.
So, do you mean 2nd or 3rd collapse on the PCH?

(9,760 posts)Well, I'm no engineer, but I would be shocked if the collapsed part of that road were repaired and safe to drive in any time soon.
I'll be happy to be proven wrong.

... when the Schoharie Creek Bridge on the NY State Thruway washed out. Two vehicles went down with the bridge and five more drove off into the gap after the collapse.
There were unconfirmed reports that some motorists who had seen the collapse (and stopped in time) tried to flag down oncoming vehicles, but were ignored by the doomed drivers. If it's true, it says something about human nature. I'm not sure what.

That's where we were stationed when my Dad did his year in Vietnam.
Sorry gettin' sentinmental here.

(5,305 posts)I was stationed at Ft Ord for two years 1970 - 72 as a member of the Army Band. Like so many at the time, I resented and hated the fact I was forced to serve in the military.
Fifty years later I look back on it as two of the best years of my life and could not think of a better place to be than the Monterrey Bay area.

(5,305 posts)In 1968 I was a 140 pound weakling scared shitless at the thought of being drafted and thrown into deadly combat in Vietnam. When I was forced to drop out of college for financial reasons the military soon came after me. After my pre-induction physical an Army recruiter gave me a call. I went to the recruiting office and was pleasantly surprised to learn that by enlisting for three years instead of waiting to be drafted for two years I could choose what job I would do and where I would be stationed for a year. I chose to enlist, be a musician, and serve in California. It was one of the best decisions I've ever made. It changed the entire trajectory of my life for the better. Monterrey is an enchanting place in so many ways and it has always held a special place in my heart.

(23,971 posts)...around 2002, from an older man who had been in one of the military bands, - Joe Varhula. Interesting guy. I recently Googled him, and there are many references to him by former students who are professional drummers and speak of him as one of the best teachers they ever had. Greater Chicago area.
I grew up in Rochester, NY, home of the Eastman School Of Music. Many Eastman grads spend some time in various of the military bands.
I spent 4 years in the Air Force Nurse Corps as a pediatric nurse practitioner. My second active duty tour was 2 years at Yokota Air Base outside Tokyo. Fascinating, and it changed my life, too. Met my husband there (pilot, next door neighbor in the BOQ). Aforementioned younger son and his older brother would not exist had I not been stationed in Japan.
I played the flute thru high school, and piano. I still have 58 yr old flute, and a wonderful old upright piano built in 1918, and I play when I am the only one homeostasis there is no one to hear my mistakes. For the past 9 years, Ive been in a handbell choir.
Do you still play?

(5,305 posts)Being from a very poor family all the normal options of a kid growing up, like music lessons etc were simply not available to me. I learned to play marching drums for free by joining the Drum&Bugle Corps in my town. I fumbled my way through high school band but lacking basic music lessons I could never play as well as the kids who started out with a teacher. The Army sent me to music school where I received my very first music lessons. My ability improved a lot during my Army enlistment, and after I was discharged I bought into the fantasy that I was a professional musician. I played in a few unsuccessful rock bands over the next few years but when I got married and started my family I just sort of grew out of it. I am proud that I was able to afford to provide music lessons for my two kids, and my son,while not professional, is now the musician I never was. You might say I'm living my fantasy through him and gives me a source of great satisfaction.

(23,091 posts)When we lived in San Jose, we'd take the trip at least once a year and drive up to Big Sur /Andrew Molera for the day. Hope they fix this so others won't lose the opportunity for too long. Also, we do plan on going back, visiting friends and of course do the Big Sur drive. Glad they weren't immediate plans for many reasons.

(6,818 posts)It's a basic "most everything must be dropped in by crane" project. The biggest challenge may be proximity to the concrete batch plant.

(2,398 posts)I've been along there, and the number of patches is dismaying. I love it... but....
When you have a relatively unstable cliff on one side of the road, and a steep drop of about 300 feet on the other, there's not much room to expand and stabilize the road.

(10,133 posts)Highway 1 south of Big Sur is a narrow, winding road built along what little land there is between the cliffs and the ocean. The winter rains, earthquakes off the coast, and gravity combine to make landslides a regular occurrence: the road only recently -like 3 or so years ago - reopened after the last landslide. The reason it's so sparsely populated along this stretch is because until the road was built in the 1930s it was practically inaccessible.
It's possible to get construction equipment in, but it requires a lot of planning and forethought: the nearest city is Monterey, about two hours in good conditions on a narrow winding two-lane road. The road is maintained and gets repaired regularly after slides, but it's not going to be quick.

(6,818 posts)It's the distance to the building materials that's the biggest challenge. I had a project 90 minutes from the nearest town years ago. In the West Fork of Susquehanna river region of Pa. mountains. Saw bears regularly on the trails to and from the work site. Logistics and resource scarcity was everything. But I preferred that to high rise projects in urban centers. Traffic control and scheduling materials deliveries as well as hassling with all the city government types makes isolated rural projects seem like a vacation.

(36,416 posts)Even asshole engineers like the late KGO radio host Dr Bill Wattenburg. His plan to use railroad flatcars to temporarily span a washed out bridge on Interstate 5, in California, was used by Caltrans. I-5 was patched up and running in, like, two weeks, but one could make the argument they jumped on it FAST because it was a critical transportation corridor.

.........................
If you go to asshole Dr Bill Wattenburg's site, you can see how easy it is to adapt it to local conditions. (The site won't let me pirate his photos)
The Modular Bridge Design: The modular bridge constructed by Caltrans is shown in Fig 2. The individual 10 ft. wide by 53 ft. long flatcar modules (Fig. 2a) are massive steel frame structures which are designed to carry loads of up to 50 tons. The flatcar modules are coupled together in interlocked fashion such that the module connections emulate pinned joints (Fig. 2b). The 50 ft. wide roadway deck of the assembled bridge consists of four flatcars side by side which span 53 ft. between two vertical piers (Fig. 2c). The piers are constructed with a single flatcar in the horizontal direction (on top) supported by two half-flatcar vertical columns. The pier structure provides its own foundation with a horizontally placed flatcar on the ground at the foot of each pier. In the transverse direction, two diagonal steel braces are added to provide stability and stiffness to the assembled pier structure. Strong surplus boxcar center beams are used for the diagonal braces. In the longitudinal direction, the underside of the bridge is left open without obstruction to allow for passage of traffic from cross streets or railroads spanned by the bridge.
A new modular multi-lane steel freeway bridge is constructed from surplus railroad flatcar decks. It can be erected on site in a few days' time. It has been built and static load tested for emergency freeway bridge repair. This inexpensive modular bridge may also have broad application around the world for low-cost bridges in areas where funds are limited. We have performed an extensive computer dynamic analysis which indicates that this simple modular design is as strong and dynamically stable as many contemporary freeway bridges, and, when used for emergency repairs, it can withstand severe aftershocks expected immediately after a major earthquake.

(21,596 posts)I have friends, who still live up way up north in Mendocino County, CA. I drove across country from Georgia in an epic road trip, camping and hiking in national parks along the way, to attend their wedding in the redwoods overlooking the Pacific Ocean. After the wedding, I drove all the way to LA, where my other good friend lived at the time, in a garden style 1920s apartment building on San Vicente Boulevard, just around the corner from Melrose Avenue.
On a later trip, I flew out to LA to see my good friend, and then drove up to see my friends in Mendocino and Humboldt counties. I drove back down to LA after that.
I may never be able to go and do that again, but I have such incredible memories of the iconic drives along California Highway 1! It is so beautiful! Great memories!

I/we would buy a place to live there.
And the occasional shutdown of Highway is a blessing and a curse. I remember a couple of years back when the north and south were both out, the residents reveled in the relative peace and quiet. Yes, it did happen during peak season, biz suffered, but community thrived.

... also, the way the road curves to the left after the outcropping.
jaxexpat
(6,818 posts)The culprit is in the depression to the left of the HWY. A drainage structure which was supposed to carry drainage under the road got filled in when the land above it slipped into the depression. All the rain water had to either fill the depression and drain over the road or saturate the road embankment, weakening it and gravity taking over. Both may have happened here. I've seen multiple tiered drainage structures which are designed to function even if dirt slides into them. They may not always work for the long term but they're comparatively cheap while eliminating emergency road closures like this.

(37,158 posts)Also from one photo in the CNN article. There aren't too many of those pull-over spots along that stretch that have trees right at their edge, so, in satellite view, I looked for one that did and confirmed it by matching up the street view.

You have to give those officers credit, they're trained to be observant and notice every subtle detail.

(8,767 posts)Such is the pattern that defines the morphology of California coastal mountains.
This at Big Sur is an extreme case of what can happen.
Anyone that experienced the 1964 Christmas Flood on the far north coast of California knows the potential active geology of the region.
