Rode this last night. It wasn't a lot of fun and one of the people I was riding with got a flat.
Apparently this will continue until mid-September, but they're going in sections so that each rough section should be paved by Friday morning (saturday if there's inclement weather). So it looks like Friday-Monday (they start milling the next section of road on Monday night) should be smooth, but Tuesday-Thursday will have crappy sections of road for a few more weeks.
