Over in my neck of the woods...
Only 1.5 miles long, but it's a start---2-way protected bike lanes on a one way street in Pasadena, CA. It officially opened today (Saturday, 9.9.2023).
I took a few pictures---while driving in my car!
Separate traffic signals for cars, bikes, and pedestrians... hopefully everyone will behave properly.

See... bikes and peds need to wait while the driver has a "protected" left turn...

2-way bike lane on a one-way street. You can see that there's a bike signal facing the other way.

There are some solid islands too, not just plastic bollards, separating bike/vehicular traffic, but I didn't take a picture. Some raised driveway aprons, too, for higher visibility of cyclists, and for cyclists to be aware of possible motorists entering or exiting driveways/parking lots.
The first signalized protected bike lanes I saw in LA County are in Long Beach, and this was probably 11 or 12 years ago. And then they installed some in downtown LA. These are the first in Pasadena, and as far as I know, they're the first in the SGV.
