Would be nice if that stretch of highway could indeed be added to the current interior bypass.
Here's one thing that troubles me (and I'm sure someone here can answer). I know that part of the reason I-69 is coming together in Texas is because the Feds allowed interstate sections to be signed (if they're at interstate quality) even if they don't currently connect to an existing other stretch of interstate.
If the I-49 article (from Ark 22 to U.S. 71) is correct about the future I-49 at Fort Smith, this will need to have adequate signage to convey that the highway essentially dead-ends at Arkansas 22, and that one will have to, at the "dead-end" turnoff, take Arkansas 22 (Rogers Avenue East, heavily traveled in east FSM) to the JK Klutz Memorial Expressway about 3 miles west, then head north on that across the Arkansas River to get to I-40, current I-540.
Maybe this is a minor issue, but this is brand new interstate rather than interstate being built along an existing highway (such as so much of Texas I-69, where it exists, is now). I'm afraid it will get confusing, even as it's exciting that apparently yet another I-49 section will be dedicated next year.
