route from Lewis & Clark end to transam east in Il

[vanick]

I'm planning on riding (for the most part) the Lewis & Clark east from Oregon starting mid July, to its endpoint in Illinois, then hooking into the TransAm route across Kentucky to my home near the cookie lady in Virginia.  

Unless I'm missing something (which is entirely possible), there seems to be a gap in the ACA mapped routes between the end of the L&C at Hartford Ill, and the TA at Murphysboro Ill.  I'm sure I can pick up an Illinois road map and figure something out, but any suggestions from those who have been there, as to a bicycle-friendly route, would be welcome.

Thanks, Nick
