Rust Belt
Every bridge you cross has a safety score. Now you can see it.
Consumer-facing US bridge safety intelligence — transforming the federal government's National Bridge Inventory (620,000+ bridges, updated annually since 1992) into a searchable, beautifully-designed, county-level bridge safety report card with individual bridge scorecards, deterioration trend charts, repair-spending accountability, and "worst bridges near you" rankings. Not engineering reports — human-readable safety journalism powered by government data.
Niche Explored
Consumer-facing US bridge safety intelligence — turning the National Bridge Inventory into human-readable safety scorecards, county-level infrastructure grades, “worst bridges near you” lookup, and accountability journalism tracking repair spending vs. deterioration.
Existing Competition
- ARTBA Bridge Report (artbridgereport.org) — annual advocacy report with state-level stats. Good data, terrible UX. PDFs and press releases only. No individual bridge lookup.
- BridgeHunter.com — hobbyist community for historic/notable bridges. No safety data, no condition reporting.
- InfrastructureReportCard.org (ASCE) — grades infrastructure categories. Updated every 4 years. No individual bridge data, no county-level drill-down.
- BetterBridges / BridgeReports.com — either defunct or paywalled B2B tools
- State DOT portals — each state has its own incompatible system. Most are GIS viewers requiring technical skills.
- Gap: NOBODY is doing automated, consumer-friendly, searchable bridge safety intelligence at the individual-bridge level with trend data, accountability tracking, and shareable visual report cards. The data is 100% public and free. It’s just trapped in government CSVs.
Data Sources Found

- BCI scores, OSIM format, every 2 years
- FHWA Bridge Condition Data — annual summary tables at https://www.fhwa.dot.gov/bridge/britab.cfm
- Pre-computed state-level summaries (good/fair/poor counts)
- USASpending.gov API — federal infrastructure spending data to correlate with repair outcomes
- Census Bureau/ACS API — population data for per-capita bridge condition scoring
SEO Analysis
- Keywords: “structurally deficient bridges near me”, “is [bridge name] safe”, “worst bridges in [state]”, “bridge safety rating lookup”, “bridges in poor condition [county]”
- Keyword difficulty: LOW to MEDIUM — dominated by news articles and ARTBA PDFs, no dedicated consumer sites
- Search volume signals: “structurally deficient bridges” spikes after every bridge collapse — consistent news cycle driver
- Long-tail opportunity: 620,000+ individual bridge pages = 620,000 indexable URLs for hyper-specific local searches
Communities
- r/infrastructure (100k+ members)
- r/CatastrophicFailure (1.5M+ members — bridge content is perennial top posts)
- r/urbanplanning (350k+ members)
- Civil engineering Facebook groups
- Local NextDoor communities (infrastructure complaints)
- Municipal council meeting audiences (accountability angle)
- Trucking/logistics communities (load-posted bridges affect routes)
Image/Graphic Feasibility
- Maps: Leaflet/MapLibre heatmaps showing bridge condition by county — trivially automatable from lat/lon + condition data
- Report cards: Letter-grade scorecards per county/state — templated SVG generation
- Trend charts: Condition deterioration over years (1992-present) — D3/Chart.js
- Before/after satellite: Harder to automate but Google Street View embeds could show individual bridges
- Infographics: “X bridges you cross daily rated POOR” — AI-generated with data overlays
- Strong visual potential overall: maps + charts + scorecards are all fully automatable
