Description: Based on the 2010 Census, Montana currently has 19 qualifying urban and urbanized areas with population of 5,000 or greater. In conjunction with the 2010 Census and in accordance with FHWA Urban Boundary Criteria, MDT staff has worked with local officials to conduct urban boundary reviews based on the latest decennial Census. The adjusted boundaries must encompass Census-defined urban areas and are subject to approval by the Secretary of Transportation [23 USC 101 (a) (36)-(37) and 49 USC 5302(a) (16)-(17)]. The revised boundaries, including the new urban areas of Columbia Falls, Glendive, Hamilton, and Sidney, were developed in cooperation with local officials and have been discussed with a representative of FHWA. MDT staff have reviewed associated roadways for functional and logical connectivity and termini and identified associated functional classification changes.

Description: A metropolitan planning organization (MPO) is a federally-mandated and federally-funded transportation policy-making organization in the United States that is made up of representatives from local government and governmental transportation authorities. The United States Congress passed the Federal-Aid Highway Act of 1962, which required the formation of an MPO for any urbanized area (UZA) with a population greater than 50,000. Federal funding for transportation projects and programs are channeled through this planning process. Congress created MPOs in order to ensure that existing and future expenditures of governmental funds for transportation projects and programs are based on a continuing, cooperative, and comprehensive (“3-C”) planning process. Statewide and metropolitan transportation planning processes are governed by federal law (23 U.S.C. §§ 134–135). Transparency through public access to participation in the planning process and electronic publication of plans now is required by federal law.
