The ½-mile span called the Tongass Narrows separates Ketchikan from Gravina Island, where Ketchikan International Airport is located. In August 2005 the 2005 Highway Bill provided for $223m to build the Gravina Island Bridge (nicknamed "the Bridge to Nowhere" by its critics) between Ketchikan and Gravina Island. The bridge would have connected the island of Ketchikan to Gravina island where the airport is located so you can drive to the airport rather than taking the ferry across the waters. After years of national and international ridicule over the expense of this project, the Alaska government ultimately chose not to build the bridge, and will spend the appropriated funds elsewhere.
