Yeah, is it really news beyond “maintainers of somewhat famous highway didn’t do very good erosion control over the years and are now suffering the consequences of that”?
It's more like highway built on fundamentally unstable coastal geology[1] falls into the ocean here and there.
[1] California is basically schmutz scraped off a subducting plate over the last 100 million years. Friend worked on a job where they excavated into a hillside behind a house and found a 10 inch wide crack filled with wet clay.
They built a tunnel to bypass devils slide. Now it's a pedestrian and bicycle path. On the Carquinez Strait there used to be a road that was abandoned due to landslides I think in the early 80's. Now is the George Miller Regional Trail.
