This pedestrian bridge crossing Greenway Parkway in Phoenix, Arizona is one of the nicest examples of such a contraption in our fair city. I have never seen anyone using it, but I am sure it must be used at some time or other or why would the state build such a thing? Matter of fact, rarely will one see a pedestrian at all on our streets. At our bus stops, it is just as likely the person waiting is not actually waiting for a bus but is using the bench to get some sleep. I have seen crazy people running down the street, not away from someone chasing them, but running for exercise – in this heat? Checking my memory I just can’t remember anyone walking that would make bridges such as this useful.
