A sorta outside the box trans am to accomplish max safety/min. traffic + most fun route selection cycling:
Employ 'Longitude Linking.'
E.G. ~ If one were choosing to consider this notion, here is how one could 'craft' such an approach.....
Start at the east coast side of the ACA Southern Tier - St. Augustine.
Travel west to either Baton Rouge or dog-leg northwest to Jackson MS.
Stop.
Pick back up at any of the following longitude equivalent vicinities:
Memphis, St. Louis (Think Katy Trail : ), Springfield IL, or Madison WI, etc. .....
Craft your route per your selection of max safety/min. traffic + most fun.
Here is a USA Longitude Map Link:

not work for the
100% "non-stop end to end coast to coast tour."
Meanwhile ... the reality is .... doing a "non-stop end to end coast to coast tour"
frequently may well have a least a point or two of breakage in the non-stop 'continuity'
where a river must be crossed and the bridge
just no way, no how offers a way for the cyclist to cross it and the cyclist gets a ride by vehicle across the bridge
and then
re-starts on the other side....
or, say, the cyclist must take a ferry across the water.
In such case(s), one does not even have what I am saying is "Longitude Linking," necessarily,
unless, of course said river crossing point is offering a 'switch back' configuration (grinning).
