Book excerpt: According to the 2016 National Bridge Inventory data, the state of Texas houses over 2100 bridges posted at load levels below the legal limit. While load postings are generally a management issue, there can be commerce, traffic, and emergency egress issues. For this reason, removing postings is always of interest. Posted structures come in all shapes and sizes, were built in different eras and environments, and exhibit vastly different structural behaviors. As such, there is no clear-cut single solution for addressing the possibility of removing postings. In this study, strategies were developed to reduce uncertainty in load rating procedures in a safe and appropriate manner to potentially increase or remove the load postings of typical steel and concrete bridges. The first phase of the project focused on the detailed review and synthesis of the relevant literature, analysis of the load-posted bridge inventory in Texas, and conducting basic load rating analysis of selected typical bridge types to identify and examine controlling limit states and areas of opportunities that could lead to an increase or removal of load posting. This Volume 1 research report fully documents the state-of-the-practice and state-of-the-art on load rating of existing bridges, the review and synthesis of the bridge characteristics of load-posted bridges in Texas, and the basic load rating for selected representative bridges to identify the controlling limit states that likely lead to an increased operating load for these bridges.
