Let's see. The longest trip I've ever taken on Interstates has to be the trip to Metropolis, Illinois in 2019. I took Interstate 40 going east and Interstate 70 going west. 

The second longest has to be the trip from Des Moines, Iowa to Orange County, California in December. I took Interstates 35 and 40. 

RV Travel has posted an article on the best Interstate routes.

They begin it with:

In the video below, we join Kyle, aka the Geography King, for his countdown of the six best interstate routes for cross-country road trips. The “Geography King” is basing his picks on his experiences taking more than 20 cross-country trips, and counting.

The video focuses on interstate highways, as most major U.S. cities are near one. And, as the topic is crossing the country, it focuses on east/west routes. Kyle chose to feature six because, well, there are only six major routes that cross the United States. So, the competition for the six-best list was, in reality, not that tough.

Those six routes are Interstates 10, 20, 40, 70, 80, and 90. Of those six, know that I-20 does not officially completely go across the entire country, but goes 2/3 of the way before ending in Southwest Texas; and I-70 only goes about 3/4 of the way before it ends in Southwest Utah.

Be sure to watch the video. In addition to what you can expect to see along each route, our host shares some creative variations and alternative routes from each that let you see even more sites.

These are the order of Kyle’s preference of cross-country routes. Yours may be different. I know I can find interesting things to see almost ANYWHERE.
