Synthesis of Information Related to Highway Practices. Topic 51-12. Night and Weekend Movement of Oversize/Overweight Loads

Movement of oversized/overweight (OS/OW) loads has traditionally been conducted on weekdays during daylight hours. However, increases in congestion have led states to consider allowing OS/OW loads to move at night and on the weekends. The states that allow night and weekend movement may not be consistent with neighboring states, creating confusion at border crossings. The objective of this synthesis is to document current state DOT OS/OW night and weekend policies and practices. Information to be gathered includes but is not be limited to: (1) State laws and regulations governing the night and weekend movements of OS/OW loads (2) Permitting practices used by state DOTs or authorized OS/OW permitting agencies (3) Characteristics of policies and practices for night and weekend movements of OS/OW loads (4) Issues and challenges that may arise from the inconsistency in policies and practices from state to state. Information will be collected through an inventory and review of state laws and regulations, a survey of DOTs, and follow-up interviews with selected agencies. Information gaps and suggestions for research to address those gaps will be identified.
