Bridge Snapshot: SR 4012
The SR 4012 bridge in Sullivan, Pennsylvania carries SR 4012 over LOYALSOCK CREEK. It was built in 1850, making it 176 years old today. It was last reconstructed in 2004, extending its service life. The structure is built primarily of wood or timber and spans 1 section, stretching 46.6 meters (153 feet) end to end. Daily traffic averages 137 vehicles, placing it in the lower-traffic tier of Pennsylvania bridges. It is owned and maintained by State Highway Agency, the entity responsible for routine inspections and any needed repairs.
The latest FHWA inspection records show a deck rating of 5/9, superstructure at 3/9, substructure at 5/9 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 0.9 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, SR 4012 is one data point in a Pennsylvania inventory that FHWA inspects on a two-year cycle (more often when ratings fall). Bridge age alone is not a reliable safety signal — a 176-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 SR 4012 compares
NBI inventory load rating (metric tons) and structural-deficiency status compared across Pennsylvania, 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 1850, this bridge is 176 years old and was last reconstructed in 2004. It carries approximately 137 vehicles per day. Based on the most recent FHWA inspection:
- • The deck (driving surface) is in fair condition (5/9), with minor deterioration that may require routine maintenance.
- • The superstructure (beams and supports above the deck) is in poor condition (3/9), showing advanced deterioration that may require priority repair.
- • The substructure (piers and abutments) is in fair condition (5/9), with minor deterioration that may require routine maintenance.
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 SR 4012?
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. SR 4012 in Sullivan, Pennsylvania has a deck rating of 5/9, superstructure rating of 3/9, and substructure rating of 5/9.
How often is SR 4012 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). SR 4012 is part of the National Bridge Inventory maintained by the FHWA. With 137 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. SR 4012 is currently classified as structurally deficient.
What is the inventory load rating for SR 4012?
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. SR 4012 has an inventory load rating of 0.9 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 SR 4012?
Bridge ownership and maintenance responsibility varies — bridges may be owned by state DOTs, counties, cities, railroads, or federal agencies. SR 4012 is maintained by State 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 SR 4012 and does age affect safety?
SR 4012 was built in 1850, making it 176 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 2004.
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.
