I recently stumbled across a February 2014 Power Point presentation that includes a slide envisioning "I-69 TXK Western Loop" going to the TexAmericas Center and north of I-30 (continuing as the Northern Loop?):

... It's also interesting that the ... slide suggests a Northern Loop connection to I-49, which makes sense considering the Intermodal Center part of the slide includes I-30, I-49 and I-69 shields.
This April 11 Texarkana Gazette article (behind paywall) reports on a recent presentation by the President of the Interstate 49 International Coalition, Curt Green, that includes emphasis on the importance of the future connection of I-49 to the TexAmericas Center:
As president of the Interstate 49 International Coalition, Curt Green let his audience know Thursday that Texarkana represented a smooth-running motor at the Economic Engines of the Ark-La-Tex meeting.
The meeting, known as the Tri-State Conference, focused on how cities such as Texarkana, which sits in I-49’s corridor, could become one of those such engines.
Green also cited TexAmericas Center ... as poised to help fuel Texarkana as an economic engine. He emphasized TexAmericas because of its large open real estate and strategic position near the future intersection of Interstate 30 and I-49—once the last 140 miles of I-49 connecting Fort Smith, Ark., to Texarkana are built.
Formed in 1997 in the aftermath of the Base Realignment and Closure Commission’s review of the RRAD, TexAmericas now has 12,000 acres available for modern industrial and commercial business development—space that is also inside a designated foreign trade zone, Green explained.
As a not-for-profit industrial development company, the center is in the process of repairing and maintaining 36 miles of rail system, 200 miles of roadway, 240,000 square feet of warehouse space and 170,000 square feet of dry storage space. ....
Texas is also getting serious about opening the Interstate 69 corridor, he said. One portion of it received official designation along a stretch of U.S. Highway 59 in Texarkana with a ceremony in September 2013.
Although the I-49 "intersection with I-30" that would provide access to TexAmericas Center, if ever, would probably be via the Northern Loop with the actual I-30 interchange being with a new terrain I-369 west of the current I-369, the big picture (putting aside roadgeek details) is that the I-49 boosters are joining the the I-69 Corridor boosters in emphasizing the importance of good access to the TexAmericas Center.
Otherwise, the article does not have any new I-49 funding or construction developments, but it does include a new rallying cry for I-49 boosters: "Too Close to Stop Now":
Green gave the audience an update on the interstate’s status, since it’s “Too Close to Stop Now,” when it comes to completion.
“Where we are today?” he asked. “We have a roadway that is now 80 percent complete, with 5 percent of that remaining 20 percent now being worked on in the 140-mile stretch between Fort Smith and Texarkana. The remaining 15 percent of that stretch still needs funding. Since work started on getting the interstate extended north throughout the rest of Louisiana in the 1980s, you can see that Louisiana has done a good job of making it a financial priority down here.”
