The bill authorizes a public highway authority or a governmental
partner in a public-private partnership to apply to the Colorado state patrol (CSP) for a new or modified hazardous materials route designation for a road or highway that it directly or indirectly maintains. The bill also requires the department of transportation (CDOT) to conduct a study to assess the feasibility of allowing the transportation of hazardous materials
through the Eisenhower-Edwin C. Johnson Memorial Tunnel and prepare a study report that includes findings and recommendations as to whether and under what conditions the transportation of hazardous materials through the tunnel should be allowed. CDOT must solicit input from representatives of specified counties, towns, communities, ski resorts, industries, organizations, emergency services providers, and the CSP regarding the scope of the study and must consider specified information and criteria and conduct specified types of analysis when conducting the study.
