Question: Is Ketchikan International Airport or Watertown International Airport further west in the United States?
Context: The Gravina Island Bridge, commonly referred to as the "Bridge to Nowhere", was a proposed bridge to replace the ferry that currently connects the town of Ketchikan, Alaska, United States, with Gravina Island, an island that contains the Ketchikan International Airport as well as 50 residents.  The bridge was projected to cost $398 million.  Members of the Alaskan congressional delegation, particularly Representative Don Young and Senator Ted Stevens, were the bridge's biggest advocates in Congress, and helped push for federal funding.  The project encountered fierce opposition outside Alaska as a symbol of pork barrel spending and is labeled as one of the more prominent "bridges to nowhere".  As a result, Congress removed the federal earmark for the bridge in 2005.
