Factory Shoals Pedestrian Bridge Study
Cobb County is carrying out a focused study of the Factory Shoals Road and I-20 area to better understand mobility and pedestrian safety needs for crossing I-20 and within the surrounding study area near Factory Shoals Road and I-20. The study kicked off in spring 2024 with completion planned for spring 2025. The planning effort will result in recommendations and a preferred plan of action for safer pedestrian conditions in the study area (see below for map).
The study team will consider pedestrian connections over I-20 at Factory Shoals, transit implementation improvements, and other potential roadway safety improvements needed in the area. Recommended connections or improvements will improve travel for those who rely on walking and/or transit to reach their daily needs.
Cobb County is dedicated to providing safe and equitable travel routes for all travelers – pedestrians, transit riders, cyclists, and drivers - throughout the county.
The community’s experiences traveling in the area are a key part of the study!

I-20 Crossing Alternatives and Transportation Enhancements
Survey
The County hosted an online survey in April 2025 to collect public input on different alternatives to improve the pedestrian crossing at I-20 and Factory Shoals Road as well as related transit and transportation safety enhancements. Thank you to everyone that participated.
Study Area
Stakeholder Group and Related Activities
A group of key community members and leaders are meeting three times during the study process to provide information and feedback to inform the study. Additionally, the study team will be holding focused discussions and interviews with unique groups within the study area, including industrial area businesses and users with a special relationship to the area.

Active Studies
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.
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 winter of 2024.
“The survey is now closed"

Cobb Parkway at McCollum Parkway Realignment Study Completed
The county has completed the Cobb Parkway at McCollum Parkway Realignment Study. This study assessed the existing roadway network, including sidewalks, bike lanes, safety conditions, and key traffic characteristics such as volume, travel times, and congestion levels. The findings establish a baseline for the further development and evaluation of roadway alignment alternatives, which are detailed in the accompanying document. These alternatives aim to improve congestion, safety, and connectivity throughout the study area.

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.
