EquipmentWorld.com | November 2015 27 Methodology: Conducted since 1979, Equipment World's Better Roads Bridge Inventory is an exclusive, award-winning annual survey that asks bridge engineers across the nation to provide qualitative and quantitative details about bridge conditions. Through consultation with states, the Federal Highway Administra- tion (FHWA) has assigned a suffi- ciency rating to each inventoried bridge measuring 20 feet or more. Factors for these ratings are outlined in the current FHWA report, "Recording and Coding Guide for Structures Inventory and Ap- praisal SI&A of the Nation's Bridges." The qualitative data are collected through our questionnaire about major issues concerning bridge conditions and maintenance. In the event a state did not respond to our survey, we used data from FHWA's National Bridge Inventory. The FHWA's explanation of structurally deficient and functionally obsolete bridges is available on the Policy & Government Affairs Conditions and Performance section of FHWA's website. The Equipment World editorial staff would like to thank state highway engineers for their continuing coopera- tion and special effort to provide cur- rent data, which was collected through October 2015.
