At the rate of growth that it's going in, I recommend that TxDOT starts working on the designing phases of upgrading US 83 within Sullivan City to the interchange with FM 2360. This would be especially true if La Joya and Sullivan City grow at the same rate Penitas did from 2000 to 2010. Plus, La Joya had announced that it will build their new fire station.
I really don't think most Americans outside of South Texas realize just how many people live in the Rio Grade Valley region. IMHO, an I-2 upgrade of the US-83 corridor up to Laredo is necessary.
There are plans and studies in progress for areas West of Sullivan City. The cluster of cities from Roma to La Puerta will eventually get a freeway bypass, which could be a further extension of I-2. I think the segment of US-83 from the end of the La Joya bypass thru Sullivan City to La Puerta could be upgraded to Interstate quality along the existing US-83 ROW. It would be a tight squeeze though.
Interstate upgrades of US-83 between Roma and Laredo would be easier since the territory is more desolate. The towns of Zapata and Siesta Shores would need a new terrain bypass out to the East. I imagine there might be an outcry about that from local businesses. But the upshot is the towns would be more visible on the map being connected to the Interstate network.
I do. Approximately 1.3 million in the Rio Grande Valley, 2/3 of them in the McAllen area and 1/3 of them in the Brownsville area. And growing! As is most of Texas. Very little of Texas is depopulating, Texas overall is one of the fastest-growing states, especially in the Triangle.
Yeah, I would say I-2's extension could be desired, possibly needed. Although I would say an upgrade of primarily Texas 71 between Austin and Columbus to Interstate quality and designating it I-12 is a higher priority.
You have to remember though, Texas is one of the few states that has very reasonable speed limits on its highways. Among the best in the nation! They need Interstates and multi-lane divided highways more for capacity than they do speed!
I would LOVE to have Texas's speed limits! Tennessee's speed limits, especially on their Interstate highways, suck! As does most of the East! Where you have 75 and 80 mph speed limits on your expressways (even 85 on Toll Texas 130!), we are stuck with...70.
