Cobb County Mobility SPLOST 2024


A Mobility Special Purpose Local Option Sales Tax (MSPLOST) referendum will be presented to voters on the November 2024 ballot in Cobb County. It will be Cobb’s first transit-related referendum since 1967.

On December 12th, 2023, the MSPLOST’s Program of Projects was approved by the Cobb Board of Commissioners and, per the HB930 process, a number of steps between the County, cities, and Atlanta-region Transit Link Authority (ATL) took place between February and June of 2024. These steps are listed in the timeline at the bottom of this page. On June 6th, 2024, the ATL board unanimously approved Cobb’s Project List for referendum consideration by the Cobb County Board of Commissioners. On Tuesday, June 11th, 2024, the Cobb County Board of Commissioners voted 3-2 to approve the Mobility SPLOST referendum for the November 2024 ballot.

If approved by voters, the one penny sales tax would collect a projected $10.87 billion over thirty years to fund transit-related projects. High capacity transit (BRT, ART) and microtransit would be the focus. According to the Program of Projects Overview, this expansion will provide the following transportation improvements to Cobb County:

  • Regional mobility through direct connections to three MARTA Stations (Dunwoody, Arts Center, and HE Holmes)
  • Connectivity to Hartsfield-Jackson International Airport
  • Countywide microtransit zones providing transportation for all including disabled, veteran, and elderly populations
  • Transit connectivity to all seven cities and three Community Improvement Districts within Cobb County
  • Transit connectivity to Kennesaw State University, Life University, Chattahoochee Technical College, and other higher education institutions
  • Transit connectivity to key entertainment venues, business centers, and healthcare institutions
  • Construction of bicycle and pedestrian facilities to provide comfortable connectivity and access to the expanded transit system
