planning a cross country bike route

Belda

Hi everyone, I'm planning a bike trip for two people
starting in San Diego and ending in New Brunswick, NJ. I've
broken the trip down to about 20 legs and I'm asking people
for their routes from one point to the next. However, some
places that we're going to seem out of the way, so I was
wondering if anyone could tell me how to pick certain
highways on a map to choose as part of the trip.

What I'm concerned about is what roads are limited
access and prohibit bicycling. I know as a general
rule bicyclists should stay off the interstate, but
which highways are preferrable? Thank you for your
help in advance.
