History
In July 1998, the Metro Atlanta Chamber of Commerce created a board to study the root causes of air pollution in Atlanta to advert the U.S. Environmental Protection Agency's threat of withholding $475 million in federal transportation funding from the region. The board presented several recommendations to then-Governor of Georgia Roy Barnes including the creation of a centralized regional planning authority.[2] In January 1999, Barnes introduced legislation creating the Georgia Regional Transportation Authority to the Georgia Senate.[3] The legislation was officially signed into law on March 23, 1999.[4]
In June 2017, GRTA combined offices and staff with the State Road and Tollway Authority (SRTA).[5]
