The American Association of State Highway and Transportation Officials (AASHTO) Innovation Initiative (AII) selected the steel press-brake-formed tub girder (PBTG) bridge system as a 2021 Focus Technology. AII will invest time and resources to accelerate the adoption of PBTG among AASHTO member associations, local agencies, and industry partners to improve U.S. infrastructure.

Researched and tested by the Short Span Steel Bridge Alliance (SSSBA), the PBTG is an accelerated bridge construction system consisting of modular galvanized shallow trapezoidal boxes fabricated from cold-bent structural steel plate. The National Steel Bridge Alliance (NSBA) is a member organization of SSSBA.
