The Non-radioactive Hazardous Materials (NRHM) routing process establishes which roads may be
used to transport certain hazardous materials. NRHM routes
are typically developed by local jurisdictions (such as a
city or county) and must
follow the guidelines established by
federal regulations. The state rules for designating
NRHM routes are in the
Texas Administrative Code.
Although TxDOT is responsible for reviewing and approving NRHM routes, we are not involved with issuing permits for
the actual movement of hazardous materials. For information
on permits, contact
the
Commercial Vehicle Enforcement Service of the Texas
Department of Public Safety at (512) 424-2051. For more information on the development of NHRM
routes, please
contact us.
NOTE: The accuracy of NRHM route maps is limited
to the validity of data as of the date of each map. Please
consult the applicable local ordinance or code for more
detailed information.
