Recently, there were some road "improvements" on the stretch of PCH in Long Beach. Added to the road were some really poorly implemented bike lanes. I would argue that they do more harm than good. The southbound lane abruptly ends in several spaces, one of which is a bridge with some surface irregularities.
This is a quintessential example of people with no bicycling expertise designing bike facilities. I mean, it doesn't take a genius to see that the lanes are dangerous. I wonder how many people have to be nearly run over or run over before things change. Anyway, here is a short assemblage I'm going to be showing at a presentation tomorrow with some city people.
