2018 AADT levels on US-71 between Fort Smith and Texarkana vary greatly depending on location. It's 28000 just South of the AR-549/US-71 junction South of Fort Smith. It drops to around 8300 close to Huntington. It dips to as little as 2800 going through the mountains between Waldron and Mena. AADT levels get back up over 10000 between Ashdown and Texarkana.

Current AADT levels along US-71 are not really enough to say "NO'' to building I-49 between Fort Smith and Texarkana. It's very certain a great deal of long distance traffic moving through the region chooses other Interstate or 4-lane US highway corridors rather than taking that stretch of US-71. Much of that segment of US-71 is a 2 lane route. Forests run pretty thick along many parts of the route.

I think it's pretty likely AADT levels would jump quite a lot if I-49 was completed between Fort Smith and Texarkana. An existing 2 lane road isn't going to achieve AADT levels typical of a rural Interstate highway when the Interstate isn't built there yet.

Good points. I was just curious what the current traffic was like. I read the Highway commission report and saw a lot of unfunded projects. I also saw one picture of a road with 4 lanes and a yellow strip with a center lane that looked a little narrower than the driving lanes. Is that the Arkansas design for the non interstate 4 lanes it is building?
It's an interesting design. Does it save much money over a divided?

I'm not a big fan of those 4-lane highways with a really skinny center "lane." That middle lane really isn't wide enough to properly function as a left turn lane. There is no barrier between opposing lanes of traffic. So it doesn't take much for someone having a sudden spaz moment or driving inattentively to cross that "median" into the opposing lanes. A true median or a Jersey/cable barrier would be a good idea.

To answer your question, yes, it is usually cheaper to build a single 4˝ lane wide roadway on a single landscaped berm rather than build up two separated berms with their own 2-lane carriageways, shoulders, landscaping, drainage, etc.

It's very certain a great deal of long distance traffic moving through the region chooses other Interstate or 4-lane US highway corridors rather than taking that stretch of US-71.
US-167 between Alexandria and Little Rock is mostly 4-lane divided highway, with the exception of a short stretch in southern Arkansas that is 3-lanes that has an alternating passing lane, and I-40 between Little Rock and Fort Smith is all interstate highway.

That routing is only about 10 miles slower than I-49 / US-71, and only a few minutes slower. It’s likely much truck traffic / long distance traffic utilizes US-167 / I-40 over I-49 / US-71 for these reasons.

Thanks Missouri is a fan of the 3 lane. They don't have the money for those either.I just went through Iowa after a snow and the narrow Interstate medians and those little fences don't help that much.

As currently estimated, the new Bentonville Walmart headquarters (2024) and the I-49 Bella Vista Bypass (2022) are estimated to be completed within a couple of years of each other.  Don't quite know how each will affect the other, but watching the changes (and needs) thereafter will be quite interesting.:
