The state of Washington has received a $90,000 grant to study the feasibility of using old aircraft carriers to bridge the Sinclair inlet. From Popular Mechanics:
In the not-too-distant future, drivers in Washington state could cross the Sinclair Inlet on a bridge made of two or three decommissioned aircraft carriers. It may sound like a wild pipe dream or a portrait of military dystopia, but the idea is under active consideration by the state, which has received federal funds to study its feasibility.
