Some kind of horizontal deflection — a curve to the side can still be used to slow bikes near an intersection. But here the original design practically required getting off the bike to go through it, while the path around it will hardly slow bikes at all. So both attempts were failures.
Here’s example of a newly constructed protected bike lane which curves as it approaches an intersection to slow bike traffic.

This looks deadly.
Because of the curve for cyclists? That’s fine.
It’s an upgrade from the old condition of no protection at all.
