Night Work/Off Peak Work
Increasingly high traffic volumes on many highways make it difficult to perform work operations in or near travel lanes during much of the day because of the disruption in traffic flow and the risk this introduces for the workers and the traveling public. As a result of these concerns, all kinds of highway work are increasingly scheduled for off-peak periods, particularly at night, to alleviate the problems associated with working in traffic.
