Cobb County Mobility SPLOST 2024


A Mobility Special Purpose Local Option Sales Tax (MSPLOST) is under consideration for referendum on the November 2024 ballot in Cobb County. It would be Cobb’s first transit-related referendum since 1967.

In December 2023, the MSPLOST’s Program of Projects was approved by the Cobb Board of Commissioners and, on February 1st, 2024, was reviewed by the Atlanta-region Transit Link Authority (ATL). This first ATL readthrough opened a 30-day period for public comment, which is the current stage of the process. Next steps include an official ATL amendment, a meeting of Cobb cities, a BOC resolution to establish its intent to call for referendum, an ATL approval of that intent, and another BOC resolution to place that referendum on the November 2024 ballot. To read more about the timeline, see the bottom of this webpage.

If included on the ballot and 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
