This document discusses the advantages of conducting road construction work at night. It notes that nighttime construction reduces traffic, resulting in fewer accidents and injuries. It also lessens distractions, allowing jobs to be completed more quickly and cost-effectively. Additionally, nighttime work improves air quality by reducing traffic delays and idling that contribute to pollution. While road worker fatalities remain a risk, working at night when there are less vehicles on the road can significantly improve safety compared to daytime construction.
