The United States Marine Highway Program is a Maritime Administration-led program to expand the use of our Nation's navigable waterways to relieve landside congestion, reduce air emissions, and generate other public benefits by increasing the efficiency of the surface transportation system (https://www.maritime.dot.gov/grants/marine-highways/marine-highway). This dataset contains the locations of all 35 maritime routes that have been designated as Marine Highways by the Secretary of the U.S. Department of Transportation. Routes included in this dataset are diagrammatic and may not depict all waterways and port connectors that are considered to be part of the U.S. Marine Highway System. A data dictionary, or other source of attribute information, is accessible at https://doi.org/10.21949/1529036 This data provides users with information about the marine highway locations for national and regional analysis applications.

Users are advised to read the rest of the metadata record carefully for additional details. This shapefile is created by identifying segments of the U.S. Army Corps of Engineers' National Waterway Network that correspond to the individual Marine Highway routes. Route lengths were determined by calculating the geodesic distance in statute miles using the Web Mercator projection (EPSG 3857). data is updated as deemed necessary Jake Tsubota U.S. Maritime Administration (MARAD) Economist 1200 New Jersey Ave. SE Washington DC 20590 United States jake.tsubota@dot.gov party that accepts accountability and responsability for the data and ensures appropriate care and maintenance of the resource
