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 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 longer <br />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 2023 Annual Bridge Report <br />
