Transit Planning

Transit Center Studies

Cobb County Department of Transportation and CobbLinc are planning the development of three multimodal transit centers to meet current and future transit ridership and operational demands.  The expansion and relocation of the two existing CobbLinc transfer facilities at Cumberland and Marietta will address capacity and operational issues.  A third facility will be developed to serve operations in the South Cobb area.  All three facilities were identified in Cobb County’s recently adopted Cobb Forward Comprehensive Transportation Plan 2050 (CTP).

Cobb County is completing background planning studies, including system analysis, site evaluation, public and stakeholder outreach, and environmental documentation in two study phases:

  • The first phase, currently underway, will provide a systemwide operational analysis and a needs assessment to determine the overall need for the transit centers, general locations most suitable for the facilities, and the size and elements required for each.  Site evaluation criteria and methodology will also be developed.  Outreach in this phase will include stakeholder coordination and interviews, as well as a rider survey.
  • The second phase will provide a separate site selection analysis, environmental screening and documentation, and conceptual site design for each of the three transit centers.  This phase will include significant stakeholder and public outreach specific to each facility.  The scope of each of these studies will also include laying out next steps for funding and implementation, including a timeline for land acquisition, design, and construction of the facility.

Phase 1 Transit Centers Study (Underway)

Cobb County is planning the development of three multimodal transit centers to meet current and future transit ridership and operational demands. 

The Phase 1 Study will provide a systemwide analysis and needs assessment of CobbLinc’s transit system, existing conditions and future service expansion of the system as it relates to determining locational needs, size and amenities for the future facilities in order to meet the demands of a growing population, expanded services and useful life of the facilities. This includes determining general locations for each of the three facilities that best meet current and future rider demand and provides efficiency of CobbLinc operations. This will also include a needs assessment to determine the types of facilities needed for each location, what rider amenities should be included, and what facilities should be included for CobbLinc drivers, dispatchers and other employees. 


The Phase 1 study is expected to conclude in April 2023


Cumberland Transit Center Site Selection Study

The Cumberland Transit Center Site Selection Study will proceed in early 2023.  This study will evaluate potential sites and select a preferred site for the relocation and improvement of the existing Cumberland Transfer Center.


The relocation of the existing Cumberland Transfer Center is identified in several regional and local plans dating back to the 2015 Cobb County Comprehensive Transportation Plan (CTP) update.  The facility is programmed in the Atlanta Regional Commission’s Transportation Improvement Program (TIP); included in The Atlanta-Region Transit Link Authority (The ATL) Regional Transit Plan (ARTP); the Connect Cobb Environmental Assessment; and in the 2017 Cumberland CID’s Blueprint 3.0.  The recently adopted update to Cobb County’s CTP identifies the Cumberland transit center as a short-term project, and it is also included as a project in The ATL’s draft Priority Investment List. 


Previously identified issues and needs driving the expansion and relocation of Cumberland Transfer Center include:

  • Bus bays are at capacity
  • Bus bays are only located on the eastbound side of Cumberland Boulevard, requiring westbound buses to make several turning movements and circulate through the Cumberland Mall parking lot after departing and prior to accessing the transfer center.
  • No parking is provided
  • No kiss and ride or transit network company (TNC)/taxi/rideshare drop-off zones.  Drop offs are done ad-hoc within bus bays, sometimes impacting operations.
  • Although located in a CID, it is not close or convenient to core office, commercial, residential areas


Marietta Transit Center Site Selection Study

The Marietta Transit Center Site Selection Study is anticipated to proceed in Spring 2023.  This study will evaluate potential sites and select a preferred site for the relocation and improvement of the existing Marietta Transfer Center.

More Information Coming Soon


South Cobb Transit Center Site Selection Study

The South Cobb Transit Center Site Selection Study is anticipated to proceed in Spring 2023.  This study will evaluate potential sites and select a preferred site for the development of a new transit facility serving the South Cobb area.

More Information Coming Soon

Connect Cobb

Connect Cobb Logo

Through the Connect Cobb project, Cobb County is developing a transit solution for the mobility needs in the Northwest Atlanta Corridor, defined as US 41/Cobb Parkway and I-75 between Cobb County and City of Atlanta. The project proposes the addition of Arterial Rapid Transit (ART) along U.S. 41/ Cobb Parkway. The majority of the ART system would operate on dedicated guideway (from the Kennesaw area to Cumberland), with continuing service in the existing High Occupancy Vehicle (HOV) lanes on I-75 to the existing Metropolitan Atlanta Regional Transit Authority (MARTA) Arts Center Station. The proposed system would begin at the terminus station at Kennesaw State University (KSU) near the intersection of Chastain Road and Frey Road. Fourteen (14) ART stations are proposed in Cobb County.

An Alternatives Analysis (AA) was completed for the project in December 2012 that identified the locally preferred dual-service alternative. An Environmental Assessment (EA) was initiated in early 2013 to further define the alternative and assess its effects on mobility in the corridor and on the surrounding environment.

Alternatives Analysis

Cobb County conducted the Connect Cobb/Northwest Transit Corridor study, an Alternatives Analysis to investigate transit options and their impact on mobility, livability and connectivity on Cobb Parkway/U.S. 41 and I-75.

The AA developed a recommended locally preferred alternative (LPA) that identified a high capacity transit system best suited for the corridor. The selection of the LPA involved analyzing several types of fixed guideway transit including light rail, BRT and dedicated busway.

In conjunction with the study, land use, economic development, and redevelopment opportunities were considered with emphasis on transit oriented development and transit station area planning. To complement the technical components of the AA, a robust public involvement program was implemented to ensure community and stakeholder involvement. The study began in August 2011 and was completed December 2012.

Following completion of the AA report, the Connect Cobb project advanced to an Environmental Assessment.

All comments received will be part of the official record. 

Environmental Assessment (EA) is approved!

In April 2015, the Federal Transit Administration (FTA) approved the EA for the Connect Cobb project for public review. Included in the EA process is a detailed evaluation of the benefits and impacts of the proposed improvements to the natural, built and social environments; preparation of ridership and travel time forecasts; and calculation of probable construction costs.

Following the close of the comment period on July 14, 2015, FTA and CCDOT will consider all comments submitted. Based on the information in the EA and the comments, FTA will make a determination on the extent of the environmental impacts.
