The roving crews don't even give a warning that there's a lane ahead closed

KYW traffic would report they were out and about, but listeners had no idea where the crews where. Several times, I was interstate speed cruising down I95 and encountered them. The first inkling was a line of traffic slowing down to funnel down to two lanes. Those roving crews are so dangerous, I'm surprised there's not a daily accident involving them.

Agree about the cattle shutes and don't forget the lane shifts.
