Just like there's a flyover taking I-69 north onto I-55 north. Oh wait.
There actually should be, IMO. A one-lane loop ramp is no way to carry a major Interstate corridor.
I-69 between Shreveport and Memphis? A major Interstate corridor? Ha.
I-69 between Shreveport and Memphis? Probably not. I-69 between Houston/South Texas and Indy? Definitely.
Either build the flyovers or shift I-69 to I-269/TN 385. Oh, wait, isn't that what you advocate for all major city Interstates to go around cities?
The point remains, though, that a one-lane loop ramp isn't the most desirable movement for TOTSO's. When/if I-69 is actually competed between Houston and Memphis, that needs to be corrected.
