I've noted on a couple of posts over the last few months the problems we're having here in Tucson as I-10 is widened through the city: No entrances or exits for several miles through the heart of the city, traffic re-routed onto frontage roads, occasional complete closures for several hours due to accidents, etc. At the end of this month the highway will be closed completely for an entire weekend. From 10 PM on Friday May 30 until 5 AM on Monday June 2, I-10 through Tucson will be completely closed. Plan accordingly.
