Abstract: The Federal Highway Administration (FHWA) is now requiring a comprehensive evaluation of bridge scour as part of the National Bridge Inspection Standards (NBIS). FHWA has established January 1997 as the completion date for scour evatuations of all existing bridges identified as scour-susceptible. The requirement to identify scour and stream stability problems at bridges will continue under the NBIS, and bridge inspectors will be responsible for recognizing these problems in the field. To provide training for bridge inspectors in this area, the National Highway Institute (NHI) supported the development of a one-day training course for bridge inspectors as a supplementary module to the longer (3 to 3–1/2 day) training course on stream stability and scour. This paper highlights the objectives and content of the bridge inspectors scour training module.
