Bridge Snapshot: STC3895;YELLOWPINE
The STC3895;YELLOWPINE bridge in Valley, Idaho carries STC3895;YELLOWPINE over JOHNSON CREEK. It was built in 1959, making it 67 years old today. It was last reconstructed in 1991, extending its service life. The structure is built primarily of steel and spans 3 sections, stretching 27.1 meters (89 feet) end to end. Daily traffic averages 70 vehicles, placing it in the lower-traffic tier of Idaho 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 8/9, superstructure at 8/9, substructure at 6/9 on the 0–9 NBI scale, where 9 is excellent and 0 is failed. The weakest component sits in fair 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 68.0 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, STC3895;YELLOWPINE is one data point in a Idaho inventory that FHWA inspects on a two-year cycle (more often when ratings fall). Bridge age alone is not a reliable safety signal — a 67-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.

How STC3895;YELLOWPINE compares
NBI inventory load rating (metric tons) and structural-deficiency status compared across Idaho, computed live from the FHWA NBI.
Condition Ratings
Ratings are on a 0–9 scale: 9 = Excellent, 7–8 = Good, 5–6 = Fair, 3–4 = Poor, 0–2 = Critical/Failed. Sufficiency rating (0–100) combines structural adequacy, functional obsolescence, and essentiality.

Condition Analysis
Built in 1959, this bridge is 67 years old and was last reconstructed in 1991. It carries approximately 70 vehicles per day. Based on the most recent FHWA inspection:
- • The deck (driving surface) is in good condition (8/9), showing no significant deterioration.
- • The superstructure (beams and supports above the deck) is in good condition (8/9), showing no significant deterioration.
- • The substructure (piers and abutments) is in fair condition (6/9), with minor deterioration that may require routine maintenance.
Its NBI inventory load rating reflects the load level it is rated to carry.
Frequently Asked Questions
What do the condition ratings mean for STC3895;YELLOWPINE?
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. STC3895;YELLOWPINE in Valley, Idaho has a deck rating of 8/9, superstructure rating of 8/9, and substructure rating of 6/9.
How often is STC3895;YELLOWPINE 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). STC3895;YELLOWPINE is part of the National Bridge Inventory maintained by the FHWA. With 70 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. STC3895;YELLOWPINE is not classified as structurally deficient.
What is the inventory load rating for STC3895;YELLOWPINE?
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. STC3895;YELLOWPINE has an inventory load rating of 68.0 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 STC3895;YELLOWPINE?
Bridge ownership and maintenance responsibility varies — bridges may be owned by state DOTs, counties, cities, railroads, or federal agencies. STC3895;YELLOWPINE 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 STC3895;YELLOWPINE and does age affect safety?
STC3895;YELLOWPINE was built in 1959, making it 67 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 1991.
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.
