Notes: Rankings are for routes in which continuous stop-and-go conditions occur with few, if any, breaks in the queue. Thus, corridors that have equally severe delays but where congestion is broken into several segments may rank lower in this type of congestion listing. Congestion is defined as average speeds below 35 miles per hour for 15 minutes or more.
