Is there ever really a "good time" for road construction?

Tennessee, as stated by truck drivers, has some of the best roads to travel, in America. and, rightly so. state workers are constantly repaving roads in Tennessee. daytime, night time, anytime, you will see roads being worked on in Tennessee. Question: in your opinion, what is the best time for roads to be “down to one lane of traffic” for repaving a road and the safety of the workers?
