Man, that is the flustercluck of flusterclucks. I wanna say that when they started, a little before the Covid mess they said it would be done in the winter of 2023/24', but I could be wrong. This MF'ing boondoggle is at least 18 months away.
What really pisses me off is that I am old enough to remember when the did the construction, and I was driving a lot back then, for the first upgrade and that crap didn't finish until about 96/97' and then the moved more west towards McAllen. I wanna say they started that in like 92', and it was no great salvation and was crowded by 99' or so.
They should have made that interchange or an alternate route much better 25-30 years ago.
The valley has always lagged behind on the other urban areas on attention to infrastructure. An acquaintance that sat on some of the regional mobility committees or whatever they are back in the 80's told me that TDOT guru's told the committee that the RGV had a big issue with mobility going east and west and there were suggestions of loops and such branching out from out west via 107 and some stuff around the HRL/BRO area to make the military road more viable. But all were killed or tabled due to well connected landowners, so it has always been back to the expressway which is now a crowded SOB.
