Multi-State, Multimodal, Oversize/Overweight Transportation

TRB’s National Cooperative Highway Research Program (NCHRP) Report 830: Multi-State, Multimodal, Oversize/Overweight Transportation is a compilation of existing permitting requirements for the transportation of oversize/overweight (OSOW) freight throughout the United States. It identifies and presents information about state-by-state differences in OSOW road transportation regulations and permitting practices, and the challenges these differences may pose for carriers. It discusses factors affecting modal competitiveness in OSOW transportation as well as opportunities for improved modal access. The report also discusses ongoing and potential opportunities to improve information and procedural applications, covering the permitting process and the need for improved communication and coordination.

Accompanying this report is a website with maps illustrating the variety and range of OSOW regulations across the United States.
