The proposed path would take I-369 over the Orr Chevrolet and Orr Honda car dealerships, if not some of the shops on the western end of the Texarkana Pavilion shopping center. I can't see I-369 being built "through" I-30 where that part of the loop currently ends
I don't think anyone is seriously considering that route anymore. Over a year ago, in
this post, I recounted parts of a conversation with a Texarkana MPO official relevant to your observation:
I-69 Spur
They are well aware that they are located on a proposed I-69 Spur, which is why they want some signage as soon as possible. The current climate for transportation funding has given rise to a fear that the I-69 Spur might be eliminated altogether. The thinking is that I-69 signage would make it more difficult to eliminate the spur ... Related to the concerns about getting spur signage as soon as possible, vocal (a minority, but vocal nonetheless) neighborhood opposition is slowing down evaluation of the West Loop alternative route to TexAmericas Center. The US 59 freeway section in question is literally the only section of the Spur that could be signed as an interstate in a relatively short period of time. He said that they could always de-designate that section as an interstate if the West Loop were to be built.
At the time, I thought having some form of I-69 signage in Texarkana in the foreseeable future was a big stretch; however, I-369 signs should be installed by the new year.
Northern Loop
A big retail center that was built around the time of the issuance of the Northern Loop FEIS has made a connection to the current US 59 prohibitively expensive. Also, even if construction of the West Loop were not a problem, preserving a Northern Loop corridor is not feasible due to both a lack of money and Texas state law having strong property protections for landowners. If connected to a West Loop, the only interchange between I-30 and I-49 would be at Richmond Road (FM 559). Regardless of whether a Freight Shuttle line would come to Texarkana, they are actively working on trying to get some type of multi-modal facility built at the TexAmericas Center.
Extending I-369 across I-30 is no longer being considered.
In a
followup post, I recounted possible justifications for construction of the Northern Loop:
He did mention that Texas A & M has recently built a Texarkana campus near a possible route for the Northern Loop and that demand may grow for a Northern Loop as that campus grows.
In the intermediate term, construction of a multi-modal facility at the TexAmericas Center and/or construction of the I-69 Spur West Loop (combined with the Texas A & M - Texarkana factor) may generate enough demand/justification/need to build it.
Above said, I think the lack of corridor preservation for the Northern Loop will likely kill it.
