The book Next Exit is excellent for travel anywhere in the U.S. It lists all Interstate highways and all exits, showing what is at that exit (fueling, motels, food, hospitals, diesel, etc.) and where they are in relation to the exit. We've used it for years.

I have pasted the link to the book at Amazon.com because it also gives plenty of info about the book as well as reviews by users of the book.
