DEFINITIONS: <br /> Weight Restricted bridges are signed to inform the traveling public of the notice of maximum vehicle <br /> weight a specific bridge can safely support.This helps to extend bridge service life by reducing the risk of <br /> damage and potential failures. <br /> Structurally Deficient is defined by FHWA as a classification given to a bridge which has any component <br /> (Deck, Superstructure, Substructure or Culvert) rated in Poor or worse condition. Structurally deficient <br /> means there are elements of the bridge that need to be monitored or repaired. The fact that a bridge is <br /> classified as structurally deficient does not imply that there is an imminent threat of collapse or it is unsafe. <br /> Functionally Obsolete is a bridge that was built to standards that are not used today. These bridges are <br /> not automatically rated as structurally deficient,and they are not inherently unsafe. Functionally obsolete <br /> bridges may not meet current standard for lane width, shoulder width or vertical clearance or those that <br /> may occasionally flood. <br /> Sufficiency rating is a rating system developed by FHWA to serve as a prioritization tool to allocate funds. <br /> The rating varies from 0 (poor) to 100 (very good). The formula considers structural adequacy, whether <br /> the bridge is functionally obsolete, and level of service provided to the public. Sufficiency rating is no <br /> longer used by FHWA.WSDOT continues to use sufficiency rating for local agency projects. <br /> Fracture critical describes a non-redundant steel tension member which is in the load path. <br /> Kittitas County 2024 Annual Bridge Report <br />
