The American Association of State Highway and Transportation Officials recently issued interim revisions to its LRFD Steel Bridge Fabrication Specifications, 1st Edition publication, originally published in 2023.

This publication governs the fabrication of steel bridges designed for vehicular traffic, as well as the furnishing and fabrication of steel structures and the structural steel portions of other structures.
AASHTO said the objective of this specification guide is to achieve quality and value from a common specification that standardizes vehicular steel bridge fabrication in the United States.
Specifically, those specifications help minimize variations among projects; provide economy, because individual fabricators would not have to change their methods and production variables; allow expertise in steel bridge fabrication to be shared among states; and enable owners to share resources, minimizing the effort each would, otherwise, spend to maintain their individual bridge fabrication specifications.
The 2025 Interim Revisions to those steel bridge fabrication specifications contain changes to six sections, including those on cutting and shearing plates and shapes, base metal repair, and bolted connections.
Meanwhile, new material has been added to three other sections and one annex, including ones encompassing steel bridge materials and bending plates.
To order a copy of the new 2025 interim revisions, visit the online AASHTO Store online and search by the publication’s item code – LRFDSFS-1-I2 – or click here for a direct link to the publication’s web page on the AASHTO Store.
AASHTO stressed that it is necessary to have the 2025 interim revisions as well as the 2024 interim revisions (Item code: LRFDSFS-1-I1) to have all current steel bridge fabrication specification information.
