Bridge Snapshot: COLUMBIA-PURVIS RD

The COLUMBIA-PURVIS RD bridge in Marion, Mississippi carries COLUMBIA-PURVIS RD over UPPER LITTLE RIVER. It was built in 1966, making it 60 years old today. The structure is built primarily of steel and spans 1 section, stretching 85.3 meters (280 feet) end to end. Daily traffic averages 810 vehicles, placing it in the lower-traffic tier of Mississippi bridges. It is owned and maintained by County Highway Agency, the entity responsible for routine inspections and any needed repairs.

The latest FHWA inspection records show a deck rating of 6/9, superstructure at 6/9, substructure at 4/9 on the 0–9 NBI scale, where 9 is excellent and 0 is failed. The weakest component sits in poor condition, which drives the overall status of this bridge. Because at least one major component scores 4 or lower, the FHWA classifies this bridge as structurally deficient — a maintenance flag, not a closure order. Its NBI inventory load rating is 19.8 metric tons — the load level the structure is rated to carry at inventory (long-term) level.

In a county that maintains hundreds of NBI-tracked bridges, COLUMBIA-PURVIS RD is one data point in a Mississippi inventory that FHWA inspects on a two-year cycle (more often when ratings fall). Bridge age alone is not a reliable safety signal — a 60-era structure can outperform a newer one when maintenance is consistent, materials are sound, and traffic loads stay within design limits. Use the condition ratings above, the sufficiency score, and the structurally-deficient flag together to read the bridge's real status, and check the linked county and state pages to see how this bridge ranks against its peers.

Every figure on this page comes directly from the Federal Highway Administration National Bridge Inventory (NBI), the public dataset that catalogs more than 617,000 highway bridges across the United States and is updated annually from the records that each state Department of Transportation submits to the FHWA. The condition codes use the standardized FHWA Recording and Coding Guide, the same scale that determines federal eligibility for the Highway Bridge Program and the Surface Transportation Block Grant set-aside for off-system bridges. A "structurally deficient" classification under those federal criteria is a maintenance and funding flag, never a closure order; states keep deficient bridges open with load posting, weight limits, or accelerated inspection cycles until rehabilitation or replacement is funded.

Condition Analysis

Built in 1966, this bridge is 60 years old. It carries approximately 810 vehicles per day. Based on the most recent FHWA inspection:

  • The deck (driving surface) is in fair condition (6/9), with minor deterioration that may require routine maintenance.
  • The superstructure (beams and supports above the deck) is in fair condition (6/9), with minor deterioration that may require routine maintenance.
  • The substructure (piers and abutments) is in poor condition (4/9), showing advanced deterioration that may require priority repair.

Its NBI inventory load rating is low, indicating a load-restricted structure. This bridge is classified as structurally deficient, meaning at least one major component is rated in poor condition. This does not mean the bridge is unsafe — it means it requires repair or monitoring.

Frequently Asked Questions

What do the condition ratings mean for COLUMBIA-PURVIS RD?

Bridge condition ratings use a 0–9 scale set by the Federal Highway Administration (FHWA). Ratings 7–9 indicate good condition with no significant problems. Ratings 5–6 mean fair condition with minor issues. Ratings 3–4 indicate poor condition requiring repair. Ratings 0–2 are critical, meaning the bridge has serious structural problems. COLUMBIA-PURVIS RD in Marion, Mississippi has a deck rating of 6/9, superstructure rating of 6/9, and substructure rating of 4/9.

How often is COLUMBIA-PURVIS RD inspected?

Federal law requires most highway bridges to be inspected at least every 24 months. Bridges in poor condition or with known issues may be inspected more frequently (every 12 months or less). COLUMBIA-PURVIS RD is part of the National Bridge Inventory maintained by the FHWA. With 810 vehicles crossing daily, regular inspection is essential.

What does "structurally deficient" mean for a bridge?

A structurally deficient bridge has at least one major component (deck, superstructure, or substructure) rated 4 or below on the FHWA 0–9 scale. This classification does NOT mean the bridge is unsafe for travel — it means the bridge needs repair, rehabilitation, or eventual replacement. Structurally deficient bridges remain open and are monitored. COLUMBIA-PURVIS RD is currently classified as structurally deficient.

What is the inventory load rating for COLUMBIA-PURVIS RD?

The NBI inventory rating is the load level a bridge is rated to carry for an indefinite period, recorded in metric tons. A lower number means the structure is more load-restricted. COLUMBIA-PURVIS RD has an inventory load rating of 19.8 metric tons. It is distinct from the FHWA sufficiency rating, a separate 0–100 funding-eligibility score that this dataset does not include.

Who is responsible for maintaining COLUMBIA-PURVIS RD?

Bridge ownership and maintenance responsibility varies — bridges may be owned by state DOTs, counties, cities, railroads, or federal agencies. COLUMBIA-PURVIS RD is maintained by County Highway Agency. The FHWA oversees the National Bridge Inventory program and sets inspection standards, but day-to-day maintenance falls to the owning agency. If you notice damage or safety concerns, contact your state DOT or call 911 for emergencies.

How old is COLUMBIA-PURVIS RD and does age affect safety?

COLUMBIA-PURVIS RD was built in 1966, making it 60 years old. Bridge age alone does not determine safety — condition depends on materials, design, traffic load, maintenance history, and environmental exposure. Many older bridges remain in good condition due to regular maintenance and reconstruction.

Disclaimer: Bridge condition data is from the FHWA NBI and reflects the last reported inspection. A structurally deficient rating does not mean a bridge is closed or unsafe for travel — it indicates the bridge requires repair or replacement. For current closure or safety information, contact your state DOT.
