The American Association of State Highway and Transportation Officials and the American Welding Society or AWS have jointly published the new AASHTO/AWS D1.5M/D1.5:2025 Bridge Welding Code, 9th Edition, now available to purchase in paperback via the online AASHTO Store.

The latest Bridge Welding Code publication covers the welding requirements for welded bridges made from carbon and low-alloy constructional steels and designed to AASHTO or American Railway Engineering and Maintenance of Way Association or AREMA requirements.
The code contains dimensions in both International System of Unit or SI Metric Units and U.S. Customary Units, AASHTO noted.
The 2025 edition of the Bridge Welding Code includes 12 sections, or “clauses,” related to welding procedures:
- Clauses 1 through 9 constitute a body of rules for the regulation of welding in steel construction.
- Clauses 10 and 11 do not contain provisions, as their analogue D1.1/D1.1M sections are not applicable to the D1.5 code.
- Clause 12 contains the requirements for fabricating fracture-critical members.
This 9th edition of the Bridge Welding Code supersedes the 8th edition, published in 2020, as well as incorporates the information contained in the 2023 and 2024 Interim Revisions, published by AASHTO.
