Crossing Guard
You trust the road. We inspect the part hanging in the air.
Consumer-facing bridge safety intelligence — an automated public-interest site that turns the National Bridge Inventory, traffic counts, flood exposure, and funding records into local bridge scorecards, commuter risk maps, county rankings, and brutally clear explainers about which bridges are aging badly, which ones carry the most people, and where repair promises are lagging reality.
Niche Explored
Consumer-facing bridge infrastructure intelligence — condition tracking, county-level scorecards, and accountability journalism for the 623,000+ bridges in the US.
Existing Competition
- ARTBA Bridge Report (artbabridgereport.org) — Industry association report, state rankings by % structurally deficient. Dry, infrequent updates, targets engineers/policymakers, not consumers. No narrative or visual storytelling.
- ASCE Infrastructure Report Card (infrastructurereportcard.org) — Gives bridges a “C” grade. Very high-level, updated every 4 years. No per-bridge or per-county data.
- BridgeHunter.com — Hobbyist/historian catalog. Not data-driven journalism. No condition analysis.
- BridgeReports.com — Paid service for inspection reports. Not public interest journalism.
Gaps Identified
- NO consumer-facing site that answers “are the bridges I drive over safe?”
- NO one doing county-level visual scorecards with trend analysis
- NO narrative journalism that names specific bridges and tells their stories
- NO automated tracking that flags when a bridge’s condition rating drops
- NO one combining NBI data with traffic data to calculate “risk-weighted crossings”
- The Francis Scott Key Bridge collapse (March 2024) created massive, sustained public interest in bridge safety
Data Sources Found
- FHWA National Bridge Inventory (NBI) — https://www.fhwa.dot.gov/bridge/nbi/ascii.cfm — Free downloadable ASCII files for every bridge in the US, updated annually. Data goes back to 1992. 445-character fixed-width records with: lat/long, year built, condition ratings (deck/superstructure/substructure on 0-9 scale), traffic counts, owner, design load, structural evaluation, and much more. 623,218 bridges in latest dataset.
- ARTBA Bridge Report — https://artbabridgereport.org/ — State-level summaries and rankings. Freely browseable.
- ASCE Infrastructure Report Card — https://infrastructurereportcard.org/cat-item/bridges-infrastructure/ — National summary statistics. $373B funding gap. 6.8% poor condition. 22,420 susceptible to extreme storms.
- Bureau of Transportation Statistics GIS data — https://geodata.bts.gov/ — National Bridge Inventory as GIS/geospatial data. REST API for querying.
- FHWA Bridge Condition by Highway System — Annual summary tables published by FHWA.
- NOAA Climate Data — Weather/flood event correlation with bridge failures.
- USGS StreamStats — River flow data for bridges over waterways.
- Wikipedia List of Bridge Failures — Historical collapse data for context and storytelling.
SEO Analysis
- Keywords: “structurally deficient bridges near me” — high intent, underserved
- “bridge condition rating” — engineering searches, growing consumer interest post-Key Bridge
- “dangerous bridges in [state]” — state-level long-tail, very little good content
- “bridge inspection results” — public records interest
- “infrastructure spending tracker” — political interest
- Search volume signals: Post-Key Bridge collapse, “bridge safety” searches spiked 400%+ and remain elevated. “Infrastructure” remains politically charged topic.
Communities
- r/InfrastructurePorn — 1.4M+ subscribers (visual infrastructure content)
- r/CatastrophicFailure — bridge collapses get massive engagement
- r/engineering — professional interest
- r/urbanplanning — policy angle
- State-specific subreddits — local bridge stories go viral
- Transportation Twitter/X — DOT officials, civil engineers, journalists
- Local news — bridge stories consistently get high engagement
Image/Graphic Feasibility
- Maps — Excellent. Lat/long for every bridge. Can generate county/state heatmaps of bridge condition.
- Trend charts — 30+ years of data enables powerful time-series visualizations.
- Scorecards — Visual report cards per state/county.
- Bridge “ID cards” — Individual bridge profiles with condition meter graphics.
- Before/after — Condition rating changes over time as visual degradation indicators.
- Risk overlays — Combine condition with traffic volume for risk-weighted maps.
