WSDOT Rail, Freight and Ports DivisionThe Washington State Freight and Goods Transportation System (FGTS) classifies freight corridors by modes in Washington state based on annual freight tonnage moved, including truck, rail, and waterway freight corridors. The Washington State Department of Transportation (WSDOT) designates and updates the FGTS every two years. This dataset depicts the waterway freight corridors classified under the FGTS system, and provides information on waterway name, link name, annual freight tonnage moved, and corridor classifications in tiers based on 2023 data.The data source for creating waterway freight corridors is the US Army Corps of Engineers, Institute for Water Resources: https://www.iwr.usace.army.mil/About/Technical-Centers/WCSC-Waterborne-Commerce-Statistics-Center/. The Link Tonngae report was used to extract cargo tonnage data by waterways in Washington State, and the GIS data of the National Waterway Network was used for mapping purposes. This GIS data is published for the 2025 FGTS update. Two other GIS datasets are also available and published for the 2025 FGTS update, including FGTS Truck Corridors, and FGTS Rail Freight Corridors.
