Bridge Snapshot: SR91 NB TPK 182.3

The SR91 NB TPK 182.3 bridge in Okeechobee, Florida carries SR91 NB TPK 182.3 over FT DRUM CREEK. It was built in 1963, making it 63 years old today. It was last reconstructed in 1990, extending its service life. The structure is built primarily of prestressed concrete and spans 8 sections, stretching 94.5 meters (310 feet) end to end. Daily traffic averages 18,350 vehicles, placing it in the heavily-trafficked tier of Florida bridges. It is owned and maintained by State Toll Authority, the entity responsible for routine inspections and any needed repairs.

The latest FHWA inspection records show a deck rating of 7/9, superstructure at 7/9, substructure at 7/9 on the 0–9 NBI scale, where 9 is excellent and 0 is failed. The weakest component sits in good condition, which drives the overall status of this bridge. No major component scores in the poor range, so the bridge is not classified as structurally deficient under federal criteria. Its NBI inventory load rating is 31.0 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, SR91 NB TPK 182.3 is one data point in a Florida inventory that FHWA inspects on a two-year cycle (more often when ratings fall). Bridge age alone is not a reliable safety signal — a 63-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 1963, this bridge is 63 years old and was last reconstructed in 1990. It carries approximately 18,350 vehicles per day. Based on the most recent FHWA inspection:

  • The deck (driving surface) is in good condition (7/9), showing no significant deterioration.
  • The superstructure (beams and supports above the deck) is in good condition (7/9), showing no significant deterioration.
  • The substructure (piers and abutments) is in good condition (7/9), showing no significant deterioration.

Its NBI inventory load rating reflects the load level it is rated to carry.

Frequently Asked Questions

What do the condition ratings mean for SR91 NB TPK 182.3?

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. SR91 NB TPK 182.3 in Okeechobee, Florida has a deck rating of 7/9, superstructure rating of 7/9, and substructure rating of 7/9.

How often is SR91 NB TPK 182.3 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). SR91 NB TPK 182.3 is part of the National Bridge Inventory maintained by the FHWA. With 18,350 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. SR91 NB TPK 182.3 is not classified as structurally deficient.

What is the inventory load rating for SR91 NB TPK 182.3?

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. SR91 NB TPK 182.3 has an inventory load rating of 31.0 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 SR91 NB TPK 182.3?

Bridge ownership and maintenance responsibility varies — bridges may be owned by state DOTs, counties, cities, railroads, or federal agencies. SR91 NB TPK 182.3 is maintained by State Toll Authority. 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 SR91 NB TPK 182.3 and does age affect safety?

SR91 NB TPK 182.3 was built in 1963, making it 63 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. This bridge was last reconstructed in 1990.

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.
