How RoadworksCheck gets its data

RoadworksCheck is an independent information service. It is not a government website and it is not run by National Highways.

National Highways

Motorway roadworks and closures come from the National Highways Road and Lane Closures API (DATEX II). That feed covers England’s strategic road network — the motorways and major A-roads National Highways operates.

Local roadworks data

Local street works come from open-data event notifications published by the Department for Transport. Town, city and postcode pages show live and scheduled works inside a 5-mile radius of the place you searched.

How often it updates

Place names and centre coordinates also use GeoNames, licensed under CC BY 4.0. We filter this dataset for UK settlements and retain our existing curated locations.

Pages refresh from the latest stored snapshot. A successful HTTP response does not by itself mean the listing is live. RoadworksCheck also looks at source timestamps and ingest times.

When data is delayed or out of date

If a feed was updated in the last 30 minutes, listings can be described as live. After that, a short public note is shown. After two hours the site does not call the data live or current. After six hours, Live now must not present those records as current roadworks. Empty or failed fetches are not allowed to wipe a previous usable snapshot.

Technical timestamps and health diagnostics stay on the private source-health endpoint, not on public pages.
