NCHRP Synthesis 20-05/Topic 51-12 [New]

Night Movement of Oversize/Overweight Loads
[ NCHRP 20-05 (Synthesis of Information Related to Highway Practices) ]

  Project Data
Funds: $45000
Staff Responsibility: Tanya Zwahlen
Fiscal Year: 2019

Preliminary Scope

Movement of oversized/overweight (OS/OW) loads has traditionally been conducted during weekday 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 movement are not consistent with neighboring states, creating confusion at border crossings. States and industry are both benefiting from night movement. In many cases states are interested in expanding their program to make more loads eligible for night travel. However, there are obvious safety concerns.
 
The objective of this synthesis is to document current OS/OW night and weekend policies and practices in the United States.
 
Information to be gathered includes but is not be limited to:
  • Laws and regulations governing the night movement of OS/OW loads
  • Permitting practices used by state departments of DOTs (e.g. electronic, paper, website availability of information, webtools, contacts, etc.)
  • Positive or negative characteristics relative to states allowing night movement
  • Effective practices for allowing the movement of OS/OW loads on nights and weekends
  • How consistency or the lack thereof of policies and permitting between states impacts this issue
Information will be collected through literature review, survey of DOTs, and follow-up interviews with selected agencies for the development of case examples. Information gaps and suggestions for research to address those gaps will be identified.
 
 
Information Sources (Partial):
  • State law, Regulation and policy documents
  • Specialized Carrier and Rigging Association
  • Special hauling permit services
