Wow! Diane and I just drove westbound through there last night. It was open then. Glad we slipped through.
The winds were indeed high. Warnings of 45 mph gusts were posted. Our fuel economy went depressingly south as we drove into a vicious headwind from the Nebraska/Wyoming border to the Continental Divide.
Speed limits were reduced to 35 mph for a stretch and I was surprised to see every single trucker obeying them. At the higher elevations snow from the ground blew across the road and formed ice. I saw two trucks jackknifed in the ditches there. Maybe those were the two who ignored the 35 mph before we came through, or maybe the speed limit had not yet been reduced before they wrecked out.
