report synthesizes existing literature on nighttime construction operations, identifies gaps in the current state of knowledge, and summarizes research in progress studies that are planned or underway. The literature review and synthesis found the following: there is no statistically significant difference between nighttime and daytime operations in terms of safety; there is no difference in productivity levels between nighttime and daytime operations; quality of work does not seem to be affected by working at night; user cost decreases when work is performed at night; there is no consensus on whether construction cost increases or decreases for work at night; nighttime work may affect worker health negatively, as in any other night shift work; traffic congestion and delays are significantly reduced or eliminated with nighttime operations, which in turn leads to air quality improvement; noise pollution and vibrations can be of concern to for nighttime as well as daytime work; and new technologies are effectively addressing concerns over light pollution during nighttime operations.
Project engineers used a QuickZone analysis that included multiple scenarios for extending the lane closure duration time and the number of lanes clos...
