Regional Transportation Plan

The Regional Transportation Plan (RTP) is a long-range blueprint that prioritizes spending on transportation projects in the 20-county Atlanta region for the next two decades.

The RTP is developed by the Atlanta Regional Commission, which is the federally designated Metropolitan Planning Organization for metro Atlanta, along with the region’s transportation agencies and local governments. The boundaries of the Atlanta MPO can be explored in this interactive map.

The RTP is updated every four years and is the transportation element of the Atlanta Region’s Plan, the region’s comprehensive, long-range plan. Transportation projects seeking federal funding must be included in the RTP, along with any projects that might impact air quality.

The current RTP invests over $93 billion through 2040 to maintain and improve roads, highways, transit, and bicycling/walking facilities in metro Atlanta. Nearly two-thirds of the funding will be used to maintain and modernize the region’s existing systems, while $29 billion is programmed for major expansion projects.

RTP Highlights

  • Widen major thoroughfares and improve highway interchanges
    The Atlanta Region’s Plan includes $7.7 billion to widen the region’s network of major arterial roads and upgrade interchanges on freeways, the backbone of the region’s transportation system. In all, 185 major roads will be widened, from Ga. 20 in Cherokee County to Ga. 155 in Henry County, adding a total of 1,035 lane-miles of capacity. In addition, the plan calls for major upgrades to 22 existing interchanges and constructing 13 new interchanges by 2040.
  • Build a network of managed toll lanes that offer a way around the gridlock
    Imagine hopping on a freeway during rush hour and traveling at least 45 miles per hour across the region. That’s the promise of managed toll lanes – a free-flowing ride for people willing to pay a toll, carpool or ride a bus. The plan will nearly triple the miles of freeway corridors with managed lanes, from around 70 today to over 200 by 2040.
  • Expand transit service to better connect our region’s major employment centers and improve mobility
    Any attempt to improve mobility in the Atlanta region must include additional transit options. The Atlanta Region’s Plan commits nearly $12 billion for potential transit expansion projects, including MARTA projects in Clayton County, Ga. 400, I-20 East and the Clifton Corridor, one of the region’s largest employment centers. Most of these projects won’t be built for several decades or more unless additional local funding is identified.
  • Help local governments create more walk- and bike-friendly communities, with improved access to jobs and transit
    The plan will expand the region’s network of bicycle and pedestrian trails and foster the development of communities that offer increased walking and biking options, as well as improved access to transit, jobs and services. About $300 million still remains available from a total $500 million commitment to fund transportation projects, such as sidewalks and bike lanes, through ARC’s Livable Centers Initiative.

The cost to implement the transportation vision defined by this plan is estimated to range between $110 billion and $115 billion through the year 2040, meaning there is a shortfall of $17 billion to $22 billion to implement the full vision of the plan.

Transportation Improvement Program

The Transportation Improvement Program (TIP) is the short-term portion of the RTP, covering a six-year period. The TIP allocates federal funds for the region’s highest-priority transportation projects. Projects in the TIP must be fully funded.

ARC is committed to enforcing the provisions of Title VI of the Civil Rights Act of 1964 and taking positive and realistic affirmative steps to ensure the protection of rights and opportunities for all persons affected by its programs, services, and activities.
