Since your intended beginning and ending points don't seem to be directly on any of our routes, you may have to create your own. To start, you'll want to get in touch with the bike coordinators for the states in which you will be traveling through and check their online resources. The bike coordinators have a wealth of information that they can distribute for no charge. Most every state publishes a bicycle map of their
state that they will send out for free. And while the maps aren't as detailed as ours, they generally offer suggested roads for cycling through
their state. But every little piece of information can help. Here is a link to the contact information for all of the bicycle coordinators: http://www.walkinginfo.org/assistance/contacts.cfm
I hope this helps.
