Thanks, Moose. I recall your beautiful bridge photos. I wish them luck
with their repairs.

Is it even stable enough to support a bridge?
It's not large enough to require a bridge. Long sections of Hwy 1 are
in extremely rugged terrain. Landslides and washouts are common. Many
far larger and in more difficult locations than this one. CalTrans has
a number of solutions, some really impressive. They finally tunneled
through a mountain to bypass Devil's Slide.
In creating the highway, they built the famous Bixby Bridge.

Many clones have been built since. Here's the one at Russian Gulch,
just above Mendocino, from below/behind.

And from the ocean side.

Here, I wouldn't be surprised if they mostly just cut away more
hillside and relocate inland a ways. they also have techniques for
building out over unstable areas for the outside of the pavement.
I suspect from reading that this one was a result of inadequate
maintenance and clearing of culverts. Anyway, in context, it's pretty
minor mechanically and with minimal impact on residents and
businesses, because of location.
