Shasta County, CA

500 public highway bridges

Shasta County Bridge Snapshot

According to the Federal Highway Administration's 2024 National Bridge Inventory, Shasta County, California contains 500 public highway bridges. Roughly 41.2% are rated “Good,” 44.6% “Fair,” and 2% “Poor.” Poor means the lowest applicable deck, superstructure, substructure, or culvert rating is 4 or below on the 0–9 NBI scale. It is a condition category, not a live safety or closure decision.

Responsible agencies inspect covered bridges on risk-based intervals under current NBIS rules and submit inventory data to FHWA annually. The list below shows every NBI-tracked bridge in the county. Use the “Sort by” controls to change the ordering, and click any row for its reported inspection date, traffic count, and condition fields.
