Notice of proposed rulemaking (NPRM); request for comments.

The FHWA is requesting comments on proposed revisions to its National Bridge Inspection Standards (NBIS). This proposed action is necessary to address perceived ambiguities in the NBIS that have been identified since the last update to the regulation fourteen years ago. The proposed changes would clarify the NBIS language that is vague or ambiguous; reorganize the NBIS into a more logical sequence; and make 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 and Federal agency level.
