Hawaii has 3 interstates, H-1, H-2, and H-3. The H-3 ran directly from the entrance of my base (Marine Corps Base Hawaii, Kaneohe Bay) to Honolulu, going through the mountains in a series of tunnels. It is absolutely gorgeous. I used to make that drive everyday when I was stationed there and even when it rained it was beautiful.
That makes it an understate don't it Big Truck? (Meaning that it doesn't state what it should) Interstate: adjective 1. connecting or involving different states : interstate commerce.
noun 2. a highway serving two or more states.
3. (sometimes initial capital letter) a highway that is part of the nationwide U.S. Interstate Highway System.
What a lot of people don't realize is the highways connect Hawaii to California. The H interstate system runs beneath the Pacific. When somebody invents a long distance submersible car it might make the news.
