iENGINEERING has successfully delivered the fall 2021 release for the LTBP InfoBridgeTM web portal. In addition to annual data updates, new analytical tools enable engineers and researchers to analyze and monitor performance of bridges efficiently across the US. As part of this release, some of the major enhancements implemented included the addition of new climatic attributes using the NASA Modern-Era Retrospective Analysis for Research and Applications (MERRA-2) data repository and the addition of new analytical tools for calculating bridge asset valuation using replacement, existing, and remaining values of selected bridges. In addition to the data for National Bridge Inventory (NBI) and National Bridge Element (NBE), users can now also view, download, and analyze data collected on experimental bridges (off public road bridges). Other features and data filtering enhancements were also incorporated in this fall release for LTBP InfoBridge.
InfoBridge is developed by the LTBP Program, which is an FHWA long-term research effort to help the bridge community better understand bridge performance. The overall objectives of the LTBP Program are to monitor representative samples of bridges nationwide to collect, document, maintain, manage, and disseminate high-quality quantitative performance data over an extended time horizon.
