They actually put them on one side of the road to water the other side. I may go fix them some day, but I kind of enjoy them as a monument to what happens when the entire city staff is car-bound while the politicians go on and on about wanting to "go platinum". I wouldn't want to fix them until I had a nice video of someone (it'll probably have to be me) riding through them. As has been mentioned, it's a first-world problem.
