    • Work Zone Data Exchange (WZDx) Feed Registry

    Metadata Updated: January 20, 2026

    This dataset contains the up-to-date metadata on Work Zone feeds that meet the Work Zone Data Exchange (WZDx) specifications and is registered with USDOT ITS DataHub. The current work zone data from each feed can be accessed through their respective API links. Some links provide direct access, while others require a user to create their own API access key first. Please see the attached API Key Instructions document to learn how to sign up for API keys for the requisite feeds.

    The ITS JPO has collections from 23 states covering various parts of the time period from 10/2019 to 08/2024 depending on when the feed was active. The data is split into two archive files, the raw data contains the collection of .json or .geojson files exactly as they were on the individual state’s WZDx feed at the time of collection. The processed data is organized by work zone, so that as information about the work zone changed through feed updates they would be collected in a single file for that work zone. To request access fill out the form here.
