completely left out i-24 that goes north-west out of nashville to st. louis & south-east to chattanooga

that is what makes nashville such a hub for trucking companies....3 major interstates coming in from most any direction leaving going in most any direction

i-65 goes north/south
1-40 goes east/west
& the forementioned i-24 goes north-west/south-east

they are now working on i-840 which is a connector that is about 35 miles outside of nashville that will eventually loop completely around & makes it look like a wagon wheel. so you can come in on any interstate, take it to go to any other interstate going in any other direction & not have to come into downtown nashville
