iENGINEERING has successfully delivered the fall 2022 release for the LTBP InfoBridge web portal. In addition to annual data updates, new analytical tools enable engineers and researchers to analyze and monitor the performance of bridges efficiently across the US. As part of this release, a new tool has been added to view the historical condition of bridges across multiple years. The provision of additional bridge location data from the US Census Bureau will allow the filtering of bridges by Metropolitan Planning Organizations (MPOs), Political Districts, and Cities. Historical National Bridge Elements (NBE) health index graphs and more data types for experimental bridges (off-public road bridges) were added to include structural health monitoring, visual inspection, and material testing data. This release also includes enhancements to the export and filter functions as well as several improvements to improve the user experience.
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.
