Just returned from a trip home to see the folks in Arkansas, and it looks as though AHTD has extended US-67 about 10 miles further past Newport up to AR-226. (I think this is probably old news...but the first time I've seen it..hehe) This is a big leap as it brings traffic even closer to Jonesboro and Walnut Ridge. Work has begun on the next portion, which I'm guessing would bring the freeway all the way up to Walnut Ridge. Interestingly enough, when driving on the current alignment of US-67 south from Walnut Ridge to AR-226, there's an interesting naming method for US-67 (as shown here):

Question though...is there any freeway segment planned to connect US-67 to the I-69 freeway corridor over near Dyersburg, TN? Maybe I'm the only one here, but the route that I take from Columbus, OH down to central Arkansas is as follows:
I-71S to Louisville, KY
I-65S to Elizabethtown, KY
Western KY Parkway W to I-24W
I-24W to Purchase Parkway S
Purchase Parkway S to Fulton, KY
US-51S/US-412W to Dyersburg, TN
I-155W to END I-155W/US-412W in Hayti, MO
US-412W to US-67S in Walnut Ridge, ARUS-67S to new alignment of US-67 near Cash, ARUS-67S to US-64W in Beebe, AR
US-64W to I-40W in Conway, ARI-40 to Russellville, AR
There are three big gaps in freeway/divided highway here (shown in red above): US-412W from Kennett, MO to Walnut Ridge, AR; US-67S from Walnut Ridge, AR to Cash, AR; US-64 from Beebe, AR to I-40 in Conway, AR.
I know the US-64 deal would probably never happen although it does cut about 30 mins off having to go all the way to Little Rock and back up. However, a freeway connection from US-67 to I-155 and eventually I-69 would seem like a great thing...maybe even via Jonesboro/US-63? Thoughts?
