NSBA Releases New Steel Bridge Design Handbook

February 15, 2022


CHICAGO - A newly updated and fully revised edition of the Steel Bridge Design Handbook (formerly the Highway Structures Design Handbook) is now available as a free download from the National Steel Bridge Alliance (NSBA), a division of the American Institute of Steel Construction. 


“Since it was first introduced by US Steel in the 1970s, the Handbook has been a popular and important reference for everyone involved in the design and construction of steel bridges,” notes Jeff Carlson, PE, director of market development for NSBA. “It includes the latest research and advice from the nation’s top bridge experts and includes information ranging from mechanical properties of steel to splice design to corrosion protection.” 


The original Handbook was produced by US Steel in the 1970s and quickly became a popular reference for steel bridge design. Later editions were produced by AISC and authored by FHWA, NSBA and HDR Engineering.

This current edition of the Handbook will be maintained by NSBA. It includes 19 chapters and six design examples, all in PDF format and downloadable at
