MARTA is seeking public comment on a proposed transit line along Campbellton Road in southwest Atlanta.The agency has proposed a five-mile light rail line from Greenbriar Mall to MARTA's Oakland City station, though it's also considering bus rapid transit in the corridor. As part of its study of the corridor, MARTA is conducting an online survey at https://marta.scoutfeedback.com/campbellton. You can take the survey through June 12.The project is included in a proposed $2.7 billion transit expansion in Atlanta. The expansion was made possible when city voters approved a half-penny sales tax for transit expansion in 2016.For more information on the Campbellton Road project, contact Marcus Arnold at email@example.com.About the AuthorDavid WickertDavid Wickert covers transportation issues.
