N2  - The paper describes the results of a survey of U.S. State Highway Departments in which 60% of the 47 responding states recommended using the Inventory Bridge Rating for the operation of longer-combination vehicles.  Calculations for double 48 ft and triple 28 ft vehicle configurations show that the choice of bridge rating criterion dramatically affects predicted longer-combination vehicle impacts on the rural Interstate network.  Employing these vehicle types and the Inventory rather than Operating Rating on the rural Interstate network produces 309% more deficient bridges, 531% higher affected traffic volumes, and 335% higher replacement costs.  The replacement cost rating differential exceeds $6 billion, excluding user delay costs.<p />
