API, files, or your warehouse. Daily, weekly, or hourly.

Every dataset here carries a 0–10 score built on documented fields, and the ranking follows those scores. When records tie, coverage breaks it: more geography, deeper history, finer granularity. Cadence isn't a scoring axis — it's a delivery setting. Delivered daily, weekly, or hourly, your call.

    It ranks second because it is the only record here carrying routing-ready geometry at planetary scale while keeping upstream attribution dates on every feature.

    Ranks third because joining crossings to incidents inside a single catalog removes the usual cross-agency key-matching work.

    It earns its place because those four attribute families are precisely what corridor feasibility studies otherwise lack a worldwide source for.

    It ranks below Overture for schema stability but above the planet file for practicality - most teams want one country, not eighty gigabytes.

Frequently asked questions

Which dataset covers every public US highway bridge?

FHWA's National Bridge Inventory. The 2025 edition carries roughly 624,000 records covering all 50 states plus DC, Puerto Rico and the US Virgin Islands, one row per bridge or culvert holding location, structure type, age, traffic exposure, condition ratings, appraisal results and inspection history, with editions from 1992 onward.

What is the largest road and rail network dataset by segment count?

Overture Maps' Transportation Theme. A single monthly release lists about 128 million residential segments, roughly 34.9 million service-road segments and around 1.5 million rail segments as GeoParquet, each feature carrying linearly referenced property ranges along the line and retaining its upstream edit date.

Where does railroad grade crossing and crossing accident data live?

In the USDOT catalog: a federal grade-crossing inventory of 438,762 rows across 187 columns sits alongside 251,149 Form 57 incident records across 154 columns. FRA crossing and incident series run from 1975 through the current year, which supports multi-decade safety trending at a single crossing or nationally.

How far back do US highway statistics reach?

The FHWA Highway Statistics series has published annual state tables since 1945, with within-edition trend lines reaching 1920 for road mileage and 1950 for motor fuel. The Highway Performance Monitoring System adds annual national submissions since 1978, and USDOT finance tables reach back to 1949.

Does Datadory sell the underlying sources or add value on top?

Neither. We deliver what these catalogs publish - the rows, fields and coverage documented above - normalized into stable schemas and shipped through the channel you choose. What changes is the engineering around them: parsing, typing, joins and refresh handled upstream, so your team works with tables rather than file formats.
