FLORIDA DEPARTMENT OF TRANSPORTATION BRIDGE SCOUR EVALUATION PROGRAM

Following the catastrophic failure of the Schoharie Creek bridge in April 1987 FHWA established a national bridge scour evaluation program under the National Bridge Inspection Standards to be implemented by state highway and transportation departments. Initial scour susceptibility screening was completed for the most part by October 1992, and FHWA has established January 1997 as the completion date for scour evaluations of all existing bridges identified as scour susceptible. The procedures that were developed and the results to date of scour evaluation of bridges in Florida are highlighted. The Florida Department of Transportation guidelines contain a four-phase approach to scour evaluations: Phase I is data collection and qualitative analysis, Phase II is hydrologic and hydraulic assessment for scour analysis, Phase III is geotechnical and structural scour assessment, and Phase IV is a recommended plan of action. The checklists and field procedures developed to complete Phases I and II of the evaluation are presented, and the results of the scour evaluations to date are summarized.
