Short Span Steel Bridges 
AASHTO/NSBA Release Updated Steel Bridge Fabrication QA/QC Guidelines
The following information was provided by the National Steel Bridge Alliance.
The AASHTO/NSBA Steel Bridge Collaboration has released the updated G4.1 Steel Bridge Fabrication QC/QA Guidelines.
G4.1 outlines minimum quality control and assurance requirements, guiding fabricators, contractors and owner agencies in consistent inspections and verification.
It’s an essential resource for building robust steel bridge quality management systems.
Does steel provide an economical solution for bridge construction?
- Due to the light weight of steel, cost savings can be significant
- Studies show that weathering, A1010 (A709-50CR), and galvanized steel reduces both initial and life cycle costs.
- Steel can compete and even save costs when compared with nearly identical concrete structures. re.
- Steel bridges also have long lives, decreasing the need for replacement.
- Steel’s high strength permits longer spans, minimizing disruption to underlying habitats.
- Steel is highly resistant to extreme natural disasters such as earthquakes.
- Steel is the world’s most recycled material and is infinitely recyclable.
- Short span steel bridges can be designed with prefabricated elements which provide a simpler installation and cost savings.
