The real question is what to do with the I-69 Gulf Coast traffic. It might be as expensive to upgrade I-30 / I-40 to handle the I-69 traffic as it would be to actually build I-69 through NW Louisiana and across Arkansas.
Well see, you could build I-69 to accommodate that I-69 traffic... which is why it was proposed.
The only problem is funding. It's not a useless segment, it will have viability once completed, if ever.
I agree with you. The problem is Arkansas and Louisiana are not going to build it until the feds force their hands. Mississippi might not be able to come up with any money for it even if it was. I will add one thing. The traffic volume demands a new road somewhere. I just am unsure that west of I-55 in Mississippi is the right place for a multitude of reasons.
OK -- presume that the end points of I-69's central segment remain static -- Shreveport & Memphis. The most direct route more or less follows US 79 through Pine Bluff; in fact ages ago congressman Dickey tried to get that road approved at least as a branch of the corridor, but was rebuffed because at the time (mid-'90's) Trent Lott, using his bully position in the Senate, wanted to make sure his state got a "piece of the pie". AR reconsidered their position and opted for a compromise: I-69 would cross the southern tier of their state before entering MS, there
would be considerable mileage within MS as a result, but AR would get an extension of I-530 (AR 530 for the time being) down to the I-69 corridor at Monticello, which satisfied their wish to serve Pine Bluff and LR as well. Well, Lott had to skedaddle in disgrace, his power dissipated (now lying with McConnell), so sliding funds through the back door to MS was no longer a given. So MS is back to its impecunious state, AR is juggling previously prioritized projects (say
that three times in a row!), and I-69, except for a short section of 2-lane expressway (and the Clarksdale bypass freeway) remains a dotted line on a planning map. But that dotted line has to go
somewhere; at least Lott did recognize that the MS Delta region along US 61 could benefit from a bit of "make-work" money input, so US 61 became, at least in part, the default alignment. But the potential alternatives within MS just aren't that great either -- if the corridor headed east along MS 8 to Grenada, it would still involve about 56 miles of construction from US 61 to I-55, while the current plan features a 30-mile stretch north to Clarksdale and its bypass freeway. If taken directly east from
there on US 278, it's still another 36 miles or so to get to I-55. But it's only 50 miles from Clarksdale to the stub-end of extant I-69 northeast of Tunica. So there's about 80 miles of construction between Cleveland and current I-69 versus 56 miles east to Grenada and 66 miles to Batesville via Clarksdale. Something of a mileage saving for sure by shunting directly to I-55 -- but at a distinct inconvenience in terms of both mileage and time to the driver -- particularly the commercial driver who is concerned about such things.
In a policy world more rational than seen today, IMO the optimal solution from a C/B basis would be to (a) relegate the current construction along US 278 in AR to local use, and (b) reroute I-69 straight south on US 61 to US 82, where it could (c) cross the river on a nice new multilane bridge before continuing to US 425 before (d) turning south to Bastrop and Monroe, LA (and extending 530 south to the new US 82 alignment in the process). (e) I-69 would multiplex with I-20 west to Barksdale AFB, where it could turn south onto its Shreveport bypass alignment per existing plans. AR would still get its N-S "spine" 530 freeway, and MS would be spared a bunch of new-terrain construction west from Cleveland. Yeah, it drags commercial I-69 traffic through less of southern AR, but the prospects of using that corridor to provoke development was at best purely speculative anyway. However, the chances of that scenario happening are pretty slim; too many folks have reputations tied up with the current proposal. I for one think we're going to be looking at that dotted line for some time to come!
