Bridge Load Ratings
Load rating policies and procedures are administered by the Bureau of Bridges & Structures to ensure public safety and to comply with federal regulations and state statutes. The Bureau determines the safe load capacity of various types and sizes of structures from complex bridges such as trusses, cable-stayed and tied arches to simple culverts and single span bridges.
