In case you want the rundown on what the “Bridge to Nowhere” really refers to, here’s the Wikipedia page, which I suspect will become the subject of edit wars soon, if it already isn’t.

Short version, airport is on an island the requires a ferry to get to it. The airport serves about 200,000 people annually. The bridge would connect Ketchikan, the 5th largest city in Alaska (measuring in at about 7300 people, yes, really) to the island. The bridge would’ve cost almost $400 million.

Palin supported the bridge until she aspired for national office.
