East-West Gateway is responsible for maintaining and updating the region’s Roadway Functional Classification System mandated under federal law. Roadways are classified according to their urban or rural setting and the type of service they provide based on considerations such as: connectivity, mobility, accessibility, vehicle miles traveled, average annual daily traffic, and abutting land use. The purpose of roadway functional classification is to describe how travel is channelized through our roadway network and to determine project eligibility for inclusion in the Long Range Plan and short-range Transportation Improvement Program (TIP).

A roadway must already be classified at minimum as a planned or existing Urban Collector or Rural Major Collector in order to be eligible for federal funds allocated in the TIP. Table 1 shows the urban and rural roadway functional classes. For more detailed information on functional class criteria and characteristics please see FHWA Functional Classification Guidelines: Concepts, Criteria and Procedures. EWG is currently in the process of updating it’s own procedure manual based on the FHWA text.

To maintain the functional classification system, East-West Gateway accepts applications for functional classification revision during the months of May and November each year. A full-scale system wide review is conducted every 3-5 years.
