{ "currentVersion": 11.1, "cimVersion": "3.1.0", "id": 6, "name": "National Highway Freight Network - Primary Highway Freight System", "type": "Feature Layer", "description": "The National Highway Freight Network (NHFN) consists of four components: 1. Primary Highway Freight System (PHFS): This is a network of highways identified as the most critical highway portions of the U.S. freight transportation system determined by measurable and objective national data.2. Other Interstate portions not on the PHFS: These highways consist of the remaining portion of Interstate roads not included in the PHFS. These routes provide important continuity and access to freight transportation facilities.3. Critical Rural Freight Corridors (CRFCs): These are public roads not in an urbanized area which provide access and connection to the PHFS and the Interstate with other important ports, public transportation facilities, or other intermodal freight facilities.4. Critical Urban Freight Corridors (CUFCs): These are public roads in urbanized areas which provide access and connection to the PHFS and the Interstate with other ports, public transportation facilities, or other intermodal transportation facilities.States and in certain cases, Metropolitan Planning Organizations (MPOs), are responsible for designating public roads for the CRFCs and CUFCs in accordance with section 1116 of the FAST Act. This GIS dataset includes the first two components of NHFN network, PHFS and Non-PHFS Interstates. Another GIS dataset is also available and published for the NHFN Critical Urban and Rural Freight Corridors. The data source is FHWA and original GIS shapefiles were acquired through FHWA\u2019s National Highway Freight Network Tool in December 2019:
