FGTS Classification Tables

FGTS classifications for roadways, freight railroads and waterways are determined according to the annual gross freight tonnage they carry. The FGTS Update team reviews tabular and graphic information for errors and inconsistencies in FGTS classification. Adjustments are made to correct anomalies, ensure route continuity, and confirm consistency across jurisdictional boundaries.

State route classifications are provided by the Transportation Data & GIS Office (TGDO). Average annual truck traffic and tonnage for state highways is obtained from available permanent and short locations. Counts are converted to gross annual tons.

Note: Tonnage and truck volumes are averages for the highway section. Within the section, a variety of data sources may have been used to set the average, not just the data from a single location. Higher and lower values may be identified at spot locations within the section.

County road classifications are provided by the County Road Administration Board (CRAB) in the annual County Freight and Goods System (CFGS). Classifications are based on the same methodology used for state route designation.

City street classifications are provided by the appropriate city or town having jurisdiction of the roadway. The Association of Washington Cities (AWC) and WSDOT contact all cities and towns for updated classifications of city streets within their jurisdiction. Guidance is provided to promote consistent methodology.

Freight rail classifications are collected and provided WSDOT State Rail and Marine Office. Rail and Marine Office worked with all freight railroads in Washington State to gather data on 2010 freight tonnage carried by railroad segments. The tonnage data provided by railroads was further verified using Waybill commodity flow data acquired from Surface Transportation Board.

Freight waterway classifications are provided by WSDOT State Rail and Marine Office. Cargo tonnage by ports and by waterways information was gathered from the 2009 waterborne commerce report published by US Army Corps of Engineers Navigation Data Center and used for estimating the annual freight tonnage carried by Washington state waterways.
