Just back from a 1500 trip. We must have seen a couple thousand orange barrels and one person that we think was working. Mile after mile of closed lanes but no work go on.
I remember a while back seeing miles of of I-85 in NC closed on 1 side for several weeks with no obvious work going on. Came through 1 time during daylight and they were pressure washing the road. Guess it was dirty. Miles of 1 lane closed in WV and never did see anything going on, not even a person or a running machine. I think it is just easier to store those cones that way.
