Follow the money. While Don Young is one of the main players in this total waste of cash you know there are many others who should be mentioned as runners-up in this dog and pony show. Want to know who they are? They are actually very familiar political players. Just drive over to the area where the bridge would have landed on the shore across the water from Anchorage. It's all laid out for the mega-buck subdivisions these Einsteins had made bank on and their names are on the state funded road signs. Or you could just go on line and check out the borough land ownership records.
A few commenters have said Don and his buddies have done Alaska a world of good over the years. Well Don did succeed in one thing. When lower 48er's hear the term "bridge to nowhere" they know it refers to Alaskan corruption.  Whether Young's or Murkowski's corruption is the only confusion since there were two different bridges to nowhere. A twofer of greed is pretty rare but certainly a legacy of a sorry kind.
