Bridge designers consider various technical matters that users are not conscious. In this study, I compared bridge designer’s intention and bridge user’s attention. I analyzed that the text of reports by bridge designer and the photographs on social media as representation of bridge user's attention. The analysis for six bridges revealed that there were designs not only to make design intention correspond to the user's attention but also to not respond to user's attention. Therefore, it is worth considering items that the users don’t pay attention to.
