The Long-Term Bridge Performance (LTBP) Program is a 20-year research effort by the U.S. Federal Highway Administration (FHWA) to collect scientific performance field data from a representative sample of bridges nationwide that will help the bridge community better understands bridge deterioration and performance. The products from this program will be a collection of data-driven tools, including predictive and forecasting models, which will enhance the abilities of bridge owners to optimize their management of bridges. The paper describes a key product of the LTBP program, the Bridge Portal, which contains bridge performancerelated data mined from existing sources (National Bridge Inventory, State Highway Agency bridge element level data, national weather data, traffic data, weigh-in-motion data, bridge maintenance data, and other data sources), but it also serves as a central repository for all field data collected through the LTBP Program. Additionally, the Bridge Portal also functions as a research and decision-making tool by implementing bridge life-cycle and deterioration modeling using both mined data sources as well as LTBP-acquired field data to allow users to investigate bridge performance on many different levels.
