Published February 7, 2023

On May 6, 2022, at 87 FR 27396, FHWA published a final rule updating 23 CFR part 650, subpart C - National Bridge Inspection Standards (NBIS). The final rule incorporates by reference the Specifications for the National Bridge Inventory (SNBI), which is dated March 2022. These Questions & Answers (Q&As) aim to facilitate implementation of the SNBI. If your question is not addressed by these Q&As, please email your question to: NBIS_SNBI_Questions@dot.gov.

Since the SNBI is incorporated by reference in NBIS (23 CFR 650.317(b)(1)), there is some NBIS discussion in this document. There are separate Q&As for the NBIS, which should be referenced for clarification on the regulatory requirements.

Except for any cited statutes or regulations, the contents of these Q&As do not have the force and effect of law and are not meant to bind the public in any way. These Q&As are intended only to provide information regarding existing requirements under the law or agency policies.
