Description:

Abstract: The Fixing America's Surface Transportation Act (FAST Act) repealed both the Primary Freight Network and National Freight Network from Moving Ahead for Progress in the 21st Century Act (MAP-21) and directed the FHWA Administrator to establish a National Highway Freight Network (NHFN) to strategically direct Federal resources and policies toward improved performance of highway portions of the U.S. freight transportation system. The FAST Act also directed the FHWA Administrator prepare and submit to Congress a report that describes the conditions and performance of the NHFN biennially. The first Highway Freight Transportation Conditions and Performance Report is published as a standalone document and will also be included in the 23rd edition of the Conditions and Performance report to be published on a later timeline. The NHFN includes the following subsystems of roadways:

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. The network consists of 41,799 centerlines miles, including 38,014 centerline miles of Interstate and 3,785 centerline miles of non-Interstate roads.

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. These portions amount to an estimated 9,843 centerline miles of Interstate, nationwide, and will fluctuate with additions and deletions to the Interstate Highway System.

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. Nationwide, there are 4,412 centerline miles designated as CRFCs.

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. Nationwide, there are 2,213 centerline miles designated as CUFCs.

Purpose: The primary purpose of this geospatial data set is to serve the FHWA needs in highway freight planning, policy analysis, visualization of the NHFN database and network modelling.

Data Quality Information:

Attribute Value Accuracy Information:

Attribute Accuracy Report: Quality checks were for cross referencing purposes. The dataset was cross-referenced with the state dataset to determine if the spatial data and attribute data were accurate within each state.

Logical Consistency Report: The uniqueness of entity IDs and the values of begin and end milepost values were generated by the computer algorithm developed under ArcGIS Pro 2.6.1 environment.

Completeness Report: All NHFN links with HPMS 2019 GIS network representation have been conflated to the NHFN.

Positional Accuracy:

Horizontal Positional Accuracy:

Horizontal Positional Accuracy Report: The original elements of the NHFN have been conflated to the ARNOLD 2019 GIS network, which requires spatial resolution of 1:100,000 or better. However, most of the state submitted data has spatial resolution between 1:5,000 to 1:10,000.
