FMCSA updates National Haz Mat Route Registry

May 4, 2015

The Federal Motor Carrier Safety Administration announced the latest update of the 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 transportation of highway route controlled quantities (HRCQ) of Class 7 (radioactive) materials (RAM) (HRCQ/RAM) and non-radioactive hazardous materials (NRHMs) transportation.

The updated listing supersedes the NHMRR published on July 14, 2014, and includes current route limitations and allowances, and information on State and Tribal Government routing agency contacts reported to FMCSA as of March 30, 2015. The notice also responds to comments received on the Agency's Notice and request for comment on this subject published on July 14, 2014.

The effective date for the NHMRR was April 29. To find the most up-to-date listing of hazmat routes, access the NHMRR at: http://www.fmcsa.dot.gov/regulations/hazardous-materials/national-hazardous-materials-route-registry.
