  • Bridges inspected every 24 months, except:
  • Annually for:
  • Movable bridges
  • Structurally deficient bridges

  • Report:Photographs:Sufficiency Rating (SR)
  • FHWA standard measures service condition
  • Three separate group factors determine SR Rating
  • Structural adequacy (Deck, Superstructure, and Substructure)
  • Serviceability and functional obsolescence
  • Essentiality for public use
  • Condition and function are rated to current standards (not what the bridge may have been built to)
  • FHWA Coding GuideSufficiency Rating (SR) Cont’d
  • 100 percent would represent an entirely sufficient bridge; 0 is insufficient or deficient bridge
  • Rating is not a quantitative measure of safe versus unsafe
  • Example, a 50 year old bridge may be structurally adequate but deficient due to current roadway widths, standards, or clearance
  • Milwaukee Bridge Performance
  • SR of bridge inventory trending upwards
  • Milwaukee Bridge Performance
  • Relative comparison of SR for city rated bridges, 2010
