Action
Final rule.
Summary
The FHWA is revising its regulation on the National Bridge Inspection Standards (NBIS). This action is necessary to address perceived ambiguities in the NBIS that have been identified since the last update to the regulation in 1988. The changes clarify the NBIS language that is vague or ambiguous; reorganizes the NBIS into a more logical sequence; and makes the regulation easier to read and understand, not only by the inspector in the field, but also by those administering the highway bridge inspection programs at the State or Federal agency level.
