Study: Route 10 Modifications

Route 10 operates between the Marietta Transfer Center and MARTA’s Arts Center Station via Cobb Parkway (US 41) and Interstate 75. Route 10 is CobbLinc’s busiest route, carrying 25% of all CobbLinc boardings. Cobb County DOT initiated a study in 2015 after an increase of reports from Route 10 patrons of overcrowding and poor on-time performance. The study has identified the root causes of these issues and has recommended proposed service modifications as corrective actions that can be quickly implemented in a cost-effective manner.

I-285 Top End and Westside Express Lanes

The I-285 Top End Express Lanes is a major Georgia DOT project planned to improve mobility along the I-285 top end in metro Atlanta, one of the most heavily traveled and congested interstate highways in America. More than 240,000 vehicles travel across this stretch of highway every weekday. The project focuses on adding two new elevated, barrier-separated express lanes in both directions of I-285, alongside the existing general purpose lanes

Learn more on GDOT's I-285 Top End project page.


The ​I-285 Westside Express Lanes will add new, optional express lanes consisting of one new buffer-separated express lane in each direction on I-285 between I-20 and I-75 to improve mobility on I-285. The I-285 Westside Express Lanes will be part of the larger Georgia Express Lanes network.

DBE Program

Cobb County has established a Disadvantaged Business Enterprise (DBE) program in accordance with regulations of the U.S. Department of Transportation (USDOT), 49 CFR Part 26. In order to be in compliance with the DBE program regulations, the County is required to establish and submit an annual goal for the Transit Program relative to anticipated Federal funds to be expended during the Federal fiscal year.

All DBEs in Georgia are certified by Georgia Department of Transportation or MARTA. Cobb County does not maintain a listing of certified DBE contractors.

Completed Studies

Austell Road Access Management Study

Bicycle and Pedestrian Improvement Plan (2010)

Comprehensive Transportation Plan 2030

Cobb County conducted a 22-month Comprehensive Transportation Planning (CTP) study. The project kick-off began in early 2006 with the completion of the study in 2008. The CTP is a long-range transportation study that will review and analyze existing transportation needs (mobility, transit, multi-use trails, and sidewalks, etc.) as well as future transportation needs.

In January 2006, Cobb County (unincorporated) and the six incorporated cities: Acworth, Austell, Kennesaw, Marietta , Powder Springs, and Smyrna joined forces to conduct a countywide comprehensive transportation plan. The focus of which is to connect transportation decisions to land use policies to better serve the County and the metro-region of Atlanta. The Board of Commissioners updated and replaced CTP 2030 with the adoption of CTP 2040 in May 2015.


Plan Summary dated February 27, 2008

Comprehensive Transportation Plan 2040 Update

The Cobb County Comprehensive Transportation Plan 2040 (CTP 2040) has been prepared to serve as the blueprint for all transportation investments —vehicular, transit, freight, pedestrian, and bicycle—by Cobb County and its municipalities for the next 25 years. CTP 2040 integrally links land use and transportation within the County and its incorporated areas to efficiently and effectively address the needs identified for the transportation network through 2040.

Jointly developed with Cobb County and the cities of Austell, Acworth, Kennesaw, Marietta, Smyrna, and Powder Springs, CTP 2040 is the result of an extensive public involvement process and represents an understanding and agreement among policy makers and staff for the policies and information included herein.

The planning process, which kicked off in spring 2013, concluded in summer 2015 with adoption of the completed plan by each jurisdiction, as follows:

  • Cobb County – May 26, 2015

Trail System Map
Cobb County Trail System Map

Cobb County’s 32 family-friendly tree-lined trails offer the perfect outdoor escape for families, pedestrians and bicyclists. While portions of the trail network are recreational, many trails provide connectivity between cities, access to regional activity centers, and healthy commuting options for travelers wishing to avoid road congestion.

Sidewalk Policy

Sidewalks in District 2

Cobb County is committed to providing sidewalks on (at least) one side of major roadways and thoroughfares across the County. Sidewalks keep communities healthy by providing safety, mobility and accessibility benefits to citizens. Using limited funding, Cobb County prioritizes sidewalk placement in areas that are:

  • In close proximity to schools
  • In close proximity to trailheads
  • Near park and high activity areas
  • In support of public transit
  • Cost effective

Can I Get Sidewalks In My Neighborhood?

Currently, Cobb County requires all developers to install sidewalks in new-build developments. Typically, the cost of new sidewalks is absorbed, by the homeowner, in the cost of the new home.

But not every neighborhood in Cobb County, due to location or age, have sidewalks or sidewalk access. There are several options available to residents who wish to consider installing sidewalks.

Step One: Present a Request for Creation of a Sidewalk District 

Any property owner may begin the process by presenting a request for the creation of a Sidewalk District to the Cobb County Department of Transportation (CCDOT). This request allows the members/homeowners of that community, provided they meet the required conditions of Sec. 106-111, the possible option to finance the cost of sidewalk construction if all other subsequent provisions are met.

Sidewalks in District 1

Step Two: Boundary Determination 

Once the request is received, the CCDOT will determine the boundaries of the proposed Sidewalk District. This information will be provided to the applicant requesting the Sidewalk District.

Step Three: Petition for Approval

Once boundaries and cost estimates are determined for the proposed Sidewalk District, the applicant will be required to distribute the information among neighboring lot owners of the proposed district. If at least 75 percent of lot owners approve its creation, and there is no request for a public hearing about the proposed Sidewalk District, the Board of Commissioners can take action to approve creation of the District.

Step Four: Division of Cost

Each property owner in the newly created Sidewalk District will be assessed a share of the cost, divided among all lots in the District, which can be paid in through County financing or Community Financing.

  • Option One, County Financing - Each property owner may pay their assessed portion in one of three ways: by cash, ad valorem property tax installments, or five equal annual installments.
  • Option Two, Community Financing – The community may raise the total cost of the sidewalk project.

Sidewalk Code of Ordinance

For questions regarding this sidewalk code of ordinance, contact the Department of Transportation at (770) 528-1600 or email [email protected].

Maintenance of Sidewalks

Cobb DOT will be responsible for perpetual maintenance of the sidewalks.
