Short Span Steel Bridges 
Building a Sustainable Infrastructure with Steel Bridges
In June 2022, the Short Span Steel Bridge Alliance (SSSBA), National Steel Bridge Alliance (NSBA) and University of Wyoming hosted a five-part webinar series featuring a distinguished panel of 13 industry experts which provided educational information on topics essential to the design and installation of steel bridges.
One of the sessions featured two presentations on building a sustainable infrastructure with steel bridges. The recorded session can be viewed below (please note professional development hours are not included for viewing the recorded session on this website page):

Does steel provide a sustainable option for bridges?
Steel is the most recycled material on the planet. Some of the sustainable advantages of steel include:
- Steel from a disassembled bridge can be used again for another project.
- Steel bridges can last 100 years or more, with minimal maintenance over their long service lives.
- The high strength of steel permits longer spans, which minimizes disruption to underlying habitats.
- Steel is highly resistant to extreme natural disasters such as earthquakes.
- The American steel industry has achieved a 31 percent reduction in energy intensity and a 36 percent reduction in greenhouse gas intensity since 1990.
