Roads and Highways

Improving, Expanding for Future Growth

Metro Atlanta sits at the intersection of three major interstate highways and serves as a major logistics hub for the Southeast and the nation.

The Atlanta Regional Commission, the transportation planning agency for the 20-county region, forecasts metro Atlanta’s population will reach 8 million by 2040. ARC and its partner agencies are working on a number of fronts to address this growth in order to reduce congestion and increase transportation options, while improving safety and air quality:

  • Regional Transportation Plan (RTP) – The region’s long-term transportation plan includes $85 billion to maintain and improve roads, highways and transit in metro Atlanta through 2040. Highlights of the RTP include a network of managed toll lanes on area highways and improvements to major interchanges and arterial roads
  • Transportation Improvement Program (TIP) – The TIP allocates federal funds for use in construction of the highest-priority transportation projects contained in the Regional Transportation Plan. The current TIP covers the first six years of the RTP, or 2016-2021. Projects in the TIP must be fully funded
  • Regional Freight Mobility Plan – ARC, working with a Freight Advisory Task Force, has developed a regional freight plan designed to improve the movement of goods throughout metro Atlanta.
  • Georgia Commute Options – This program encourages a range of alternative commuting options, such as carpooling, vanpooling, transit and teleworking.


  • Intelligent Transportation Systems – Overhead warning signs, efficiently timed traffic signals, traffic monitoring, and other technological advances help reduce congestion and improve safety.

Congestion Management Process

A congestion management process is the federal terminology for planners identifying congested roadways and bottlenecks and developing strategies for relief. Because parts of the Atlanta region are in non-attainment for air quality, any project that receives federal funding must be vetted through the congestion management process and must meet federal approval. ARC’s RTP serves as the Atlanta region’s “congestion management process” for federal planning purposes.
