    • Texas DOT (TxDOT) Work Zone Data Schema Version 2.0

    Metadata Updated: October 28, 2025

    This dataset provides archived lane closure occurrences within the Texas Department of Transportation (TxDOT) highway system in a tabular format.

    The ITS JPO has collections from 23 states including Texas 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.
