This is the Page about I-69 progress in Arkansas!


The only Part I've been seeing lately that's been worked on is the Monticello Bypass, and the progress has been really slow last time I checked

17 mile section of Future I-69 in Arkansas starting in 2022 (https://vpi-ldph-job-020678-hwy-278-to-hwy-65-i69-drew-and-desha-ardot.hub.arcgis.com/)

This is a public hearing being done virtually on October 6 regarding the first phase from US-278 to US-65.  It'll have 2 at grade intersections and 2 overpasses and will be a 17 mile long Super-2 with enough right-of-way for the ultimate 4 lane divided finished project.

Moving very slowly.  Like I have said before, this is needed whether the Great River Bridge ever gets built.

The funeral march in building Interstate 69 across Arkansas continues. When this new US 278-to-US 65 segment opens, I wonder what designation it will have? An extension of Bypass US 278? A revival of AR 569? Or might it be unnumbered altogether?

At least Arkansas is making progress.  I don't expect Mississippi to lift a finger to progress any further on I-69 until funding is secured for the Great River Bridge.

Mississippi wanted it when Trent Lott thought it could be paid for with funds designated for it and not being transferrable.
Now that it has to come out of a less restrictive pot of Federal funds, they would prefer to spend their allocations elsewhere.

Arkansas is building roads in the corridor. What they are building is needed whether I-69 ever comes or not. While they are buying up ROW's for a multi-lane facility, as a whole they are building two-lane roads with  periodic passing lanes. There are a few overpasses but there are more at-grade intersections. From my experience southern Arkansas has some of the least modern highways in the US. I-530 meets he overall status quo in Arkansas: Everything goes either to Little Rock or to WalMart (NWA)

The "adjunct" I-69 SIU (#28; the 530 extension) was the "consolation prize" for the failure of the "Dickey Split" I-69 alignment along US 79; it was always the part of the current I-69 configuration to garner regular attention from ADOT and their political handlers; the "trunk" of the corridor would be eked out over decades, while at least the initial lanes of 530 south of Pine Bluff and near Monticello were built in short order.  Everything that can be sold as localized improvement on the I-69 mainline will be built as such:  2 lanes on a 4 ROW with minimal structures -- and as in-place upgrades of existing routes; the Monticello-McGehee US 278 stretch, always somewhat convoluted, is essentially such a project.  The new terrain stuff from Warren southwest to the LA state line will likely be the last to even see planning efforts -- a bit difficult to sell that as anything but an I-69 segment.  My guess:  AR 530's missing section will be built well before anything but the Monticello-McGehee "improvements"; solidly in keeping with AR historic priorities.

DESHA COUNTY | November 22, 2022

Join fellow stakeholders in southeast Arkansas next week for a ceremonial groundbreaking on the next phase of construction for the Interstate 69 Corridor. Members of the Arkansas Highway Commission, ARDOT staff and local leadership will gather at ARDOT's District 2 Maintenance Headquarters Tuesday, November 29, at 11 a.m. (see map).

Designated by the United States Department of Transportation as a Corridor of the Future, this federally recognized highway will be invaluable to future freight movement across the United States.

When complete, Interstate 69 will span over 2,600 miles from Laredo, Texas to Port Huron, Michigan.

You have to remember Bob Moore is still alive and the chairman of the Arkansas Highway Commission. . ArDOT has to at least give lip service to his pet project through his hometown. I cannot see it ever being built; especially as projected. The one given is even if it is NEVER upgraded to interstate standards or even four-laned, what they are doing  will make the infrastructure better in these remote counties than it is right now or has even been.

^ That is true, providing a 65 mph super-2 with mostly control of access will be a tremendous improvement to the current roadways. Especially if they end up linking them together to create a long continuous segment.

Won't help I-69 long haul traffic per se, but will be a local / regional improvement.

It will create a "main"  highway for the areas traffic which could help draw some traffic off other roads and limit the need for improvements on those other routes.
Title: Re: I-69 in Arkansas
Post by: Bobby5280 on December 02, 2022, 12:47:56 PM
Building out a Super-2, even without controlled access, is going to be better than nothing. Right now the main goal should be securing ROW along the proposed corridor. A simple 2-lane route can get that accomplished.

I-49 between Fort Smith and Texarkana is a tougher task, even if trying to build it out initially as a Super-2, due to the more hilly territory.
Title: Re: I-69 in Arkansas

^ Any super 2 should at least be constructed with limited access right of way. There can be at grade intersections, but no private driveways.

Only the Foran Gap segment between Y City and Mena is particularly "hilly" and I'd venture to say it's much gentler than most north-south routes through the Ouachitas. But I agree, ROW purchasing is crucial at this point.

That's the idea. The entire point of building out a minimal Super 2 is to secure the future 4-lane freeway's right of way. Even secure the land needed for limited access exits. AR DOT has already done this to some degree with AR-530. They could do the same with future I-69. Just build a 2-lane road along the proposed alignment just to secure the ROW. Then slowly upgrade segments of it to Interstate standards as funding allows.

Depending on what AR DOT has planned for I-49 thru the Foran Gap they might end up having to build all four lanes at once, at least in some spots. I imagine they'll have to carve into hillsides a good bit to improve the geometry of curves and grades. If they cut into hillsides they'll have to cut enough for four lanes rather than just two.

Westerman hears ARDoT pitch for federal funding
I-69, Hwy. 82 "˜critical' projects, congressman says by Caitlan Butler | June 29, 2023 at 5:00 a.m.

https://www.camdenarknews.com/news/2023/jun/29/westerman-hears-ardot-pitch-for-federal-funding/

We just provided the congressman with an update of where we're at on the future Interstate-69 corridor through Arkansas... The Mississippi River bridge is an issue because it's so expensive. It's about a $2 billion price tag; $1.2 billion is Arkansas's portion," Tudor said. "For a small, rural state like Arkansas, there's just no way we can really fund that without federal assistance."

However, work has started on Arkansas's portion of the interstate, with two-lane sections under construction in Drew County and work scheduled to start on additional length on that road in 2025. Environmental approval has been secured for the part of the road that will run through Union County.

Does anyone else get the impression that Interstate 69 in Arkansas, when more of it is eventually built, will be an underutilized freeway? Since the only significantly-populated towns 69 will go past are El Dorado and Monticello, future 69 may not need more than two lanes total.

If I-69 is ever fully complete between Shreveport and Memphis, I think it will have decent utilization and be a viable alternative to I-30 and I-40 for southeast Texas / Mexico bound traffic. Even with the "curvy"  routing, the distance will be around the same as I-30 / I-40.

In the mean time, I-69 will be perfectly adequate at 2 lanes until it is fully linked to I-20 and I-269.

I'm skeptical I-69 will ever be completed thru Arkansas and Mississippi. The Feds would pretty much have to cover all of Mississippi's obligation. Meanwhile Arkansas has more important fish to fry in other parts of the state. I-49 and I-57 are far more plausible, realistic projects to finish.

The fact the proposed I-69 route offers little if any mileage savings versus the I-30/I-40 combo would more than likely depress traffic counts on the highway. There will be far less road-side services along I-69 than I-30 or I-40 for a long time. And it seems like a sure bet the Great River Bridge will carry a pretty hefty toll. The proposed bridge's cost is now tipping the scales over $2 billion. I'd be shocked if it was built as a free-to-cross structure. Meanwhile, IIRC, I-40 has no tolls on it for its entire length. I-30 is free with the exception of express lanes in the DFW area.

If funding is an issue for I-69 Mississippi River Bridge, why isn't US 82/US 278 Greenville bridge used to connect both states? I know it would mean I-69 would dip south and then back north after entering Mississippi, but that bridge is barely new. Or was that one of the alternatives before being eliminated in favor for a new Mississippi River crossing?

In addition to the aforementioned projects for I-49 and I-57, I would suspect that ArDOT would prioritize widening I-40 between Memphis and Little Rock over I-69. The recently-completed new bridge that carries I-40 over the White River has been built to accommodate three travel lanes in each direction, plus full inside and outside shoulders, although the bridge is currently striped for two lanes each way.

Because that would bend I-69 into an even more ridiculous "L" shape route than it already is. The currently proposed I-69 route going through McGehee and Arkansas City offers little if any mileage savings over the I-30/I-40 combo as it is. The Greenville Bridge is another 25 miles farther South from the proposed Great River Bridge location. If I-69 was routed over that bridge then all of I-69 in Arkansas and Mississippi would only be of value to local traffic. The long distance traffic would stay on I-40 and I-30. It might still work out that way anyway.

Quote from: abqtravelerIn addition to the aforementioned projects for I-49 and I-57, I would suspect that ArDOT would prioritize widening I-40 between Memphis and Little Rock over I-69.

It's ridiculous I-40 isn't already built in a 3x3 lanes or greater configuration between Little Rock and Memphis. The amount of truck traffic on that segment is unreal. A completed I-57 might work as a pressure valve to relieve some of the congestion. But that stretch of I-40 has to be upgraded regardless. If it weren't for the I-57 and I-69 projects either proposed or under construction I'd be calling for I-40 to be built 4x4 all the way from Little Rock to Memphis.

I-40 has 2023-2026 STIP items for 6 laning from the I-55 concurrency in West Memphis (Exit 277) in West Memphis to the Jennette exit (Exit 265) and for the LR end from I-440 (Exit 159) to Kerr Rd. (Exit 165).  That leaves 100 miles in between to grow the ends toward the middle eventually, but unlikely to happen completely for decades at this rate barring some earmark love unless LOS decay/AADT counts mandates otherwise.  Good news is that other than a handful of overpasses that may be narrow on the underside and one of the St. Francis River bridges, most of the rest of the bridging is already wide enough.  Just will need to build some wider berms through the ricelands.

I-69 has utility in providing another connection and bypass to Shreveport if Louisiana gets their act together, but also for avoiding the bottlenecks of Little Rock and Memphis/W. Memphis with the I-269 loop around the south and east sides of Memphis.  With all of the onshoring/nearshoring of manufacturing that's in the process of really accelerating now that it's been discovered that China really isn't our friend, but Mexico really is and can take on a chunk of the inexpensive goods along with SE Asia, which means more truck and rail traffic coming from South Texas.  Those with foresight to see where freight flows are going to be growing for the next 3 decades would be wise to invest in the road and rail links coming out of Texas.  And Louisiana needs to do more value added processing of petrochemicals to grow their economy rather than load oil and gas onto ships for overseas customers.
Title: Re: I-69 in Arkansas
Post by: Bobby5280 on July 12, 2023, 03:58:46 PM
Mexico could absorb a great deal of the manufacturing production the US has based in China currently. But Mexico has to modernize somehow into a more safe, stable and less corrupt environment in order to take on much of what was based in China. It's a pretty difficult challenge for American companies to build manufacturing plants in Mexico under the current circumstances. If the US didn't have so many drug addicts Mexico would be a much safer place to visit.

Regardless of what happens in Mexico, a great deal of business is going to exit China. The regime there is increasingly authoritarian and less friendly to international business. Worse yet, China appears to be locked in a generational demographic decline. Marriage rates and birth rates have been hitting record lows due to several economic and cultural factors. Not nearly enough young people are being born to balance out the enormous size of aging/elderly generations. China isn't going to have enough working age manpower to get a lot of things done.

Currently, political conditions are pushing businesses to move production out of China to places like Vietnam or other nations in SE Asia. Nations in Africa could benefit immensely, only if more of those nations could maintain stable governments. Africa is on the verge of being home to the majority of the world's youth (if it isn't there already). The Chinese government is already trying to establish "beach heads" there so they can emulate America's outsourcing game. Africa has great and scary possibilities for the future. It can become an economic powerhouse. Or it could be the thing that gets World War III started.

Mexico and other countries in Central America and South America are being affected by the drug trade to the US. If we could only get a handle on that situation Mexico could be the primary landing spot for businesses leaving China.

(Exit 165).  That leaves 100 miles in between to grow the ends toward the middle eventually, but unlikely to happen completely for decades at this rate barring some earmark love unless LOS decay/AADT counts mandates otherwise.  Good news is that other than a handful of overpasses that may be narrow on the underside and one of the St. Francis River bridges, most of the rest of the bridging is already wide enough.  Just will need to build some wider berms through the ricelands.
Best advice for through traffic is to exit halfway through at Brinkley, get yourself a bite and if it's a fall Friday, go watch an 8-man football game.
