Transportation and Mobility 

Middle Tennessee's transportation system, with its vast network of roads, bus routes, rail lines, sidewalks, and bicycle lanes, is the backbone of our regional economy. Coordinated planning of that system is critical to the continued growth of our local and regional economies. Planning also is important to ensure that as the system grows to manage the traffic congestion that we know is coming as a result of our economic growth and development and that it grows in a way that is sensitive to our region's valuable natural and community resources. 

In recent years, there has been a growing demand to invest in transit, sidewalks, bike lanes to provide increased transportation options. GNRC works closely with local, state, and Federal government to ensure that walking and bicycling are viable transportation options in the greater Nashville area.

Regional Transportation Planning


GNRC serves as the Metropolitan Planning Organization (MPO) for Middle Tennessee. In this role, GNRC is the federally-designated transportation planning agency for more than 3,000 square miles and more than 1.5 million people throughout Davidson, Maury, Robertson, Rutherford, Sumner, Williamson, and Wilson counties.

Serving as a regional partnership among the United States Department of Transportation, Tennessee Department of Transportation, transit agencies, local elected leadership, local planning and public works directors, the business community, and citizens across the seven-county planning area, GNRC leads in the development of the region's long-range transportation plan and short-range Transportation Improvement Program and contributes to ongoing conversations about issues such as land use, economic development, climate change, and the environment, safety and security, and public health.

GNRC's Transporation Policy Board has the authority to plan, prioritize, and select transportation projects for federal funding appropriated by the United States Congress through the United States Department of Transportation Federal Highway Administration and Federal Transit Administration, and is responsible to for ensuring the region is in compliance with federal planning requirements and national ambient air quality standards.

*NOTE: As GNRC continues to integrate resources of the Nashville Area MPO program, information can still be found on the existing MPO website.
