Description

With the implementation of MAP-21, and continuing into the FAST Act, the UDOT Structures Division has been working to develop performance measures to accurately represent the overall condition of the bridge assets throughout the state. As part of that we have developed a quantitative Bridge Health Index (BHI), which takes into account bridge condition by elements, load ratings, AADT, and various other factors. As we develop the BHI further, the overall system condition has shifted some from what has previously been seen. Limits were set to define good, fair, and poor bridge conditions to indicate the level of work needed for a structure. Good condition bridges will typically be limited to preservation treatments. Fair condition bridges will be considered for preservation treatments and minor rehabilitation. Poor condition bridges would be evaluated for major rehabilitation or replacement. This does not mean that they are unsafe or in critical need for repair, but that a repair needs to be evaluated and prioritized. The BHI is independent of the classification of Structurally Deficient. Structural Deficiency is defined by FHWA as a highway bridge with one or more poor condition rating on the deck, superstructure, or substructure. This is a higher level evaluation than the BHI and does not take into account individual bridge elements. UDOT continues to have all Structurally Deficient bridges programmed for work, while the BHI rating provides a tool for prioritizing structures for various work types.
