On-line presentation regarding possible Mississippi River crossings in the Memphis area.
I don't know how logical this sounds, but has anyone wondered whether or not I-30 should just be extended from Little Rock, cross the river on the Southern Gateway, join I-69 over to I-55, and the follow U.S. 78 instead of I-22?
