Interstate Highways in Georgia are the high-capacity controlled-access routes forming part of the Dwight D. Eisenhower National System of Interstate and Defense Highways that traverse the U.S. state of Georgia (U.S. state), connecting major cities such as Atlanta, Savannah, Augusta, Columbus, and Macon. These routes interface with federal programs like the Federal-Aid Highway Act of 1956 and regional planning bodies such as the Metropolitan Atlanta Rapid Transit Authority and the Atlanta Regional Commission, shaping transportation, commerce, and land use across counties including Fulton County, DeKalb County, and Chatham County.

Overview

Georgia's network includes major corridors linking to neighboring states Florida, Alabama, Tennessee, and South Carolina. The system supports intermodal connections to hubs like Hartsfield–Jackson Atlanta International Airport, the Port of Savannah, and Fort Benning, and coordinates with agencies such as the Georgia Department of Transportation and the Federal Highway Administration. Major metropolitan areas served include Columbus–Phenix City, Augusta–Richmond County, and the Savannah metropolitan area, with infrastructure investments reflecting policies from the Interstate Highway System era through contemporary programs like the Infrastructure Investment and Jobs Act.

Primary routes serve as long-distance trunks across Georgia, linking to corridors such as the Piedmont Atlantic Megaregion and national arteries connecting to New York City, Miami, and Chicago. Primary interstates coordinate with state routes like Georgia State Route 400 and federal routes like U.S. Route 17 and U.S. Route 1, interfacing near landmarks such as Stone Mountain, Kennesaw Mountain National Battlefield Park, and the Savannah Historic District. These highways enable freight movements to facilities including the Georgia Ports Authority terminals and military installations like Fort Gordon.

Auxiliary interstates and business loops provide urban circulators, beltways, and spur connectors serving downtown districts and suburbs, integrating with transit nodes such as Five Points (Atlanta), Midtown Atlanta, and the Savannah Historic District. They form ring roads and bypasses around cities like Athens and Warner Robins, linking to institutions including University of Georgia, Georgia Southern University, and Mercer University. These routes support access to cultural venues such as the Fox Theatre (Atlanta), Savannah College of Art and Design, and the Macon Coliseum while intersecting major corridors like U.S. Route 80 and U.S. Route 41.

The history of interstate construction in Georgia traces to national decisions at Camp David and federal legislation like the Federal-Aid Highway Act of 1956, with early planning influenced by leaders such as Presidency of Dwight D. Eisenhower and regional planners from the MARTA Planning Department. Construction projects have encountered preservation and community responses linked to sites like Sweet Auburn Historic District, Historic Kennesaw Mountain, and the Savannah Historic District. Major milestones include the opening of urban freeways during periods of metropolitan expansion, coordination with the Environmental Protection Agency on environmental review, and legal contexts involving agencies like the Department of Transportation.

Traffic management on Georgia's interstates involves partnerships among the Georgia State Patrol, county sheriffs, and municipal public safety agencies in Fulton County and DeKalb County. Safety programs reference standards from the National Highway Traffic Safety Administration and engage institutions such as Emory University and Centers for Disease Control and Prevention for research on crash mitigation. Maintenance and capital programs rely on funding measures connected to the Transportation Equity Act for the 21st Century and federal grants overseen by the Federal Highway Administration, addressing challenges posed by weather events recorded by the National Weather Service and infrastructure stresses revealed in studies by the American Society of Civil Engineers.

Interstate corridors underpin regional economic zones including the Atlanta metropolitan area, the Savannah metropolitan area, and the Columbus, Georgia micropolitan area, facilitating logistics for corporations like The Home Depot, UPS, and Coca-Cola. They support tourism flows to attractions such as Savannah Historic District, Callaway Gardens, and Okefenokee Swamp and influence land use around centers like Buckhead and River Street (Savannah). Economic development agencies including the Georgia Department of Economic Development and chambers of commerce in Chatham County and Richmond County leverage interstates for business recruitment, while academic institutions such as the Georgia Institute of Technology research transportation economics and urban planning models used by metropolitan planning organizations like the Atlanta Regional Commission.
