To be clear - this is a bike lane on a road with onramps? Uh, what? There aren't even bollards (in the part without an onramp, obviously) or any semblance of protection.
The road is a surface street -- a 30 or 35mph divided arterial which goes over a freeway. The ramp is an offramp from a freeway. But yes, there is no protection, which is normal.

The photo is taken looking towards the freeway, showing the offramp.
A typical bike lane in the US is made out of paint, the lack of protection isn't noteworthy.
