Cobb Parkway at McCollum Parkway Realignment Study
Cobb County DOT has commenced work to conduct a Scoping Study for the area of Cobb Parkway at McCollum Parkway/Kennesaw Due West Road and Old 41 Highway.
Cobb Parkway at McCollum Parkway Existing Conditions Report
The County’s objectives of this study are:
- To understand and analyze the existing traffic patterns
- To accommodate the Federal Aviation Administration (FAA) approved safety zone at Cobb International Airport
- To promote the involvement of all stakeholders in the study area
- To develop at least three minimum conceptual alternatives
- To select a preferred alternative
- To evaluate relative cost, feasibility, and constructability of alternative alignments and sections in logical phases or segments.
Through the study, the County along with its consultants, will work to better understand the traffic patterns and the issues and needs of users of the corridor to develop solutions to improve mobility. The process will result in a selected alternative for further study.
Along with data collection and analysis, stakeholder and public involvement will play a key role in assisting the study team to identify issues, develop potential solutions and evaluate alternatives. It will include a variety of outreach tools and techniques to connect and engage including a Stakeholder Committee, public meetings, and a survey.
The study is anticipated to conclude in fall of 2023.

Cobb Parkway at Windy Hill Road Grade Separation Scoping Study
Cobb Parkway (US41/SR 3) at Windy Hill Road Grade Separation Scoping Study (2016 SPLOST - X2540)
The Cobb Parkway (US41/SR 3) at Windy Hill Road Grade Separation Scoping Study will explore alternatives to improve traffic operation and safety at this heavily traveled intersection. Alternatives will be considered to grade separate Cobb Parkway and Windy Hill Road to eliminate some of the vehicle conflicts that are strangling the operation of this critical intersection. Grade separation involves aligning the roadways at different heights to reduce disruption of traffic flow when they cross each other. Other alternatives that do not physically grade separate the two roads will also be considered.
Each alternative will be appraised by a variety of factors including safety, traffic operation, cost, right-of-way (ROW), accessibility to adjacent commercial development, bicycle and pedestrian movements, constructability, and aesthetics. Stakeholder and public involvement will play a key role in identifying issues, developing potential solutions and evaluating alternatives, and as such will include a variety of outreach tools and techniques to connect and engage. The process will result in a recommended alternative for future further study.
The Cobb Parkway at Windy Hill Road intersection has long been recognized as a major source of congestion and travel delay, both locally and regionally. The project to grade separate the intersection is identified in the 2015 Cobb County Comprehensive Transportation Plan (CTP) and included in the 2016 and 2022 Cobb County SPLOST. Additionally, it is an approved roadway project in the Atlanta Regional Commission (ARC) Transportation Improvement Plan (TIP), which allocates federal funds for the highest-priority projects in the Regional Transportation Plan (RTP). This scoping study is the first step in the process to identify the appropriate improvements and determine their feasibility for this complex project.
