National Hazardous Materials Route Registry

Notice and request for comment.

This notice provides the updated National Hazardous Materials Route Registry (NHMRR), which is a listing, as reported by State and Tribal Government routing officials, of all designated and restricted road and highway routes for highway route controlled quantities (HRCQ) of Class 7 (radioactive) materials (RAM) (HRCQ/RAM) and non-radioactive hazardous materials (NRHMs) transportation. This notice also provides the limitations for using these routes. FMCSA developed this listing based on information received from State and Tribal Government routing agencies as of January 31, 2014. FMCSA is presenting the updated information with a new route-ordering format and changes to the table structure intended to improve the NHMRR usability for commercial drivers who must transport hazardous materials (HM) in compliance with routing requirements. This notice also provides current information on State and Tribal Government routing agency contacts. This listing supersedes the NHMRR published on December 4, 2000, and FMCSA requests comment on the new route ordering approach, table structure and content, and other related specific route issues from the States of Alaska, California, Colorado, and Texas, and the District of Columbia.
