AASHTO Girder

AASHTO Girder

AASHTO sections are typically used for railroad, or other private entity, bridge construction when a standard wide flange (WF) girder section does not meet the project design criteria. The top flange of AASHTO shaped girders is not as wide as standard (WF) flange beams making AASHTO a preferred design choice for bridges located in a roadway curve.
