Abstract	This report presents a bridge management system module for the selection of rehabilitation and replacement projects. The process starts with a budget to be allocated to the Texas districts and is finalized with the selection of projects to be submitted for bidding and contracting within the alloted funds. The ranking process included in both the allocation and selection processes is based on multiobjective decision theory. The developed system is composed by six computer modules, five at the state level and one at the district level. The one at the district level captures the expertise of the district engineers and includes it in the selection process. The system automates the process that recently was used to determine the district allocations and project selections in the last on and off systems Texas Highway Bridge Replacement and Rehabilitation Program. The ranking processes utilized by a selection of other states are reviewed and compared to the Texas procedures. A forecast of the funding needs for rehabilitating and replacing the Texas bridge network in the next decades is also presented.
