Agreed and on the lookout for this... I've also asked at the Fans of Route 83 Facebook page, though that is less likely to have cyclists.
The Brownsville/McAllen area is pretty populated and I've already cycled that on other routes and wouldn't take US83. I've also been through the next largest city on US 83 (Laredo, population 250,000) and driven through one of the other larger ones (Abilene, population 120,000) where I'd probably take alternate routes. Otherwise not sure there are other big population centers over 100,000 (Bismark has 70,000, Minot has 50,000) - so hopefully the lack of population centers also limits how busy the road becomes...
