To use internal or system redundancy to remove NSTM bridge status, what approval is required?

• A. FHWA Approval
• B. NSTM Approval
• C. Owner Approval
• D. No approval required

Answer: (A)

The action of using internal or system redundancy to remove a NSTM bridge status is a safety‑critical change that falls under federal oversight. FHWA approval is required because it ensures the change is evaluated against established safety criteria, properly documented, and consistent with federal‑aid bridge standards. Navy‑specific or owner approvals don’t replace this federal authorization, since the status affects public safety and the national standards that govern it. No approval isn’t acceptable because such a change must go through the formal oversight process to verify that the redundancy truly meets safety requirements and to maintain an auditable record.
