The SolTecUSA Database provides federal bridge data for all US states — posted limits, deck condition, clearances, and structure type — that supplements field surveys.
The SolTecUSA Database contains inspection and condition data for all bridges on public roads in the United States.
What SolTecUSA Data Provides** - Structure type and material - Deck condition rating (0-9 scale) - Substructure and superstructure condition - Posted weight limits (if posted) - Vertical clearance (roadway over bridge and under bridge) - Bridge authority jurisdiction (state, county, city, railroad, etc.) - Functional classification of roadway - Year built and year reconstructed
How to Use Bridge Inventory Data in Route Planning** 1. Identify bridge structures along candidate routes 2. Review deck condition ratings — structures rated below 5 may warrant special attention 3. Note posted weight limits and compare to your load configuration 4. Identify bridge authority for each structure requiring coordination 5. Cross-reference bridge data against field-verified measurements
Limitations** - Data reflects the most recent inspection cycle, not real-time conditions - Some data fields may be blank or outdated - Vertical clearances are computed values, not field-measured at the travel lane - Posted limits may not reflect current conditions after recent inspections
Best Practice** Use bridge inventory data as a reconnaissance and verification layer — not as a substitute for field measurement. It identifies structures that warrant closer examination and provides context for field findings.
