What this source cannot tell you

⚠ Anything outside United States bridges represented in the National Bridge Inventory. A request past that edge comes back empty rather than approximated.
⚠ Which years it spans, because the covered period is not declared.
⚠ Anything FHWA National Bridge Inventory does not publish. ParcelOps returns this source as it stands and never fills a blank field from a different one.
⚠ NBI fields are planning context and not route-clearance, posting, load, permitting, engineering, or inspection authority.
⚠ Verify current route conditions with the bridge owner and roadway authority before moving equipment.
