I just reminded myself that US 62 connects El Paso and Lubbock, which are 5 hours (348 miles) away
and now realized that both of these two got/getting a US 62 upgrade
and they upgraded US 62 in Lubbock before, and since they're doing the same with US 62 in El Paso, why significantly upgrade US 62 in between those two at this point?
tho granted, TX has other long-term plans (like I-27 extension and the Amarillo loop upgrade)
US - 62/180 between El Paso and Carlsbad NM passes through desolate territory. It is primarily a trucking short-cut and has served as a commuting route for those working in the oil fields of W Texas and SE New Mexico. I did work in the oil fields there for about a year, working for a geo-technical firm. Average speed ranges from 65 to 90 mph, and police presence is near non-existent. Saw a lot of risk taking and hairy passing on that stretch of highway, in the wee hours of Monday morning, and on Friday afternoons/evenings. There are intermittent "poor boy" three lane segments every 10 miles or so, to allow traffic to pass. This was done, by eliminating the shoulders in these segments. Very cheap. But better than nothing.
Would agree that a double-barreling would be beneficial, and not a New Mexico style of "flush median" four laning. Keep ranch and other access, but build a parallel carriage way, 88 feet from the existing one. Would also construct a handful of interchanges - for Dell city, for FM 1111, to Sierra Blanca, for state route 54 to Van Horn, and also for FM 652 at the NM state line. For the section through the mountains E of El Paso, would either construct a new carriage way, on different elevation, or build a narrow four lane cross-section with center jersey barrier. There is a four lane section, that has existed since 1972, which passes through Guadalupe National park, which was also created in 1972. The park has some of the best examples of Permian Period exposed rock in the world. And the highest mountain in Texas.
In summary, the argument might be that the traffic counts aren't there, for four-laning, but am of the opinion it should be done for safety. After viewing the terrible three lane "poor boy" job by texas on US - 285, NW of Pecos, and the crap on FM 652, would not hold my breath.
