What is now called the Blue Line contains some of the first sections of the MARTA rail to open. On February 19, 1975, construction on what was then known as the East Line began.[1] On June 30, 1979, service on the East Line began operating between Avondale and Georgia State.[2][1] On December 22 the same year, the West Line was opened, between Five Points station and what was then known as Hightower station (now Hamilton E. Holmes station).[1] The combined Hightower-Avondale route became known as the East-West Line.[3]
In 2009, MARTA introduced a color-coded system of naming for its rail lines.[5] As a result, the former East-West Line became the Blue Line.[6]
Future
On March 25, 2024, Andre Dickens, the mayor of Atlanta, announced plans for four new infill stations on the MARTA rail network.[7] On April 11, Dickens announced that one of those stations will be on the Blue Line: namely, Krog Street/Hulsey Yard, located on the Blue/Green Line's shared section.[8]
