The Metropolitan Atlanta Rapid Transit Authority (MARTA) has been the cornerstone of Atlanta's public transportation since its inauguration on June 30, 1979. Established to address the city's growing transportation needs, MARTA plays a vital role in connecting Atlanta and its surrounding suburbs. The MARTA rail system consists of four lines – Red, Gold, Blue, and Green – which provide extensive coverage and serve major areas of the metropolitan area. The system is characterized by its commitment to public art, with various stations showcasing creative installations. As Atlanta continues to grow, MARTA remains at the forefront with ongoing expansion projects and a vision of improved connectivity, sustainability and accessibility for diverse communities.
