Laramie, WY has for the very first time opened officially, after it was U/S for several days this past week. Except for the under construction SC in Bellefonte, PA, I-80 is now easily doable by S60s end to end. The I-10 leg between Casa Grande and El Paso looks likely to be the next to complete after I-80, but there's still nothing known to be happening in Ft. Stockton, Pecos or the San Antonio area to complete I-10 and I-20.
