Abstract In Europe, many countries are struggling with the condition of their infrastructure, particularly bridges. A significant number of bridges were constructed during the post-war era, and as a result, many are approaching the end of their service life. Another critical factor contributing to this issue is the lack of regular inspections and insufficient data for informed decision-making based on strategic planning. The approaches to condition rating systems vary across European countries, which can lead to differing final decisions on bridge maintenance and repairs. This paper focuses on the state of road bridges in Italy, Portugal, and Slovakia (Southern, Western, and Central Europe). It provides a summary of differences in rating systems, the number of bridges constructed from different materials, the distribution of bridges across various road types, and their geographical locations. Additionally, the paper discusses the principles behind these rating systems, including the COST Action TU1406, and outlines future challenges. This summary serves as a foundation for further research aimed at evaluating the application of various condition rating systems for road bridges and proposing a suitable, common European rating system, taking into account the possibilities offered by COST Action TU1406.
