America by Bike
Here is a colorful depiction of the routes that the Adventure Cycling Association have put together for modern bicyclist that want to travel and explore the country. They have put together 5 main routes which allow cyclists to cross the country in a multitude of ways. The main routes are: The Atlantic Coast, The Southern Tier, The Pacific Coast, The Northern Tier, and the Transamerican Route. The individual maps are full of great information and detail on bike friendly roads, camps and services. They can can be purchased directly from their website. If you are simply looking for the individual Google Earth KML files for these routes, they can be found at Steves website. If you want the entire Google Earth KML file containing all of these routes, just drop me a note and I will email it to you.
