These projects consist of the widening of Johnson Ferry Road from Columns Drive just north of the Chattahoochee River to Abernathy Road, and the widening of Abernathy Road from Johnson Ferry Road to Cherry Tree Lane, just east of Roswell Road.
Two alternates were originally presented. Through the input of the Citizens Advisory Committee, public information meetings, Cobb and Fulton Counties and the Georgia D.O.T.; a synthesis of the two alternates was agreed upon as the final alternate. This alternate and components are presented below:
The alternate accepted by the Citizens Advisory Committee, Fulton County, Cobb County and the Georgia D.O.T. proposes 6 lanes on Johnson Ferry Road from Columns Drive to Riverside Drive and 4 lanes from Riverside Drive to Abernathy Road. The Johnson Ferry Road typical section includes a 16’ raised median. The Abernathy Road typical section includes a variable width (16' – 32’) raised median. The intersection of Johnson Ferry Road and Abernathy Road is proposed to be reconfigured for safer and more efficient traffic operations. Other proposed features include:
- Curb and gutter, and 8' sidewalks on both sides of both roads.
- A raised median with median openings at appropriate locations. U-turns will be allowed at median openings.
- 4' bike lanes immediately adjacent to the road, one in each direction.
- The horizontal alignment of Abernathy Road will follow along the existing centerline, with widening to each side. Proposals have been made to build a "greenway" or linear park on Abernathy Road between Johnson Ferry Road and Roswell Road. Funding and design of the greenway have not been finalized. However, both Fulton County, Cobb County and the GDOT have committed to coordinate the proposed roadway improvements with the greenspace.
- Lane widths are proposed to be reduced from 12’ to 11’.
- A median opening is proposed at Barnard Place/Redding Drive.
- Wright Road will remain open as a four-legged, signalized intersection. Original concepts showed two alternates of Wright Road: one open as a four-legged intersection and one closing the southern side of Wright Road with a cul-de-sac. The decision to keep Wright Road open was made after consulting the Fulton County Fire and Police Emergency Services and agreeing that Fulton County will analyze the traffic increases after the construction of the projects. A properly maintained and timed signal system can provide better access for vehicles entering from Wright Road while sustaining acceptable operation on Abernathy Road.
- Leave Burdett Drive intersecting with Johnson Ferry Road – Burdett Drive’s alignment is proposed to show an intersection at Johnson Ferry Road an adequate distance from Abernathy Road which will allow right in and right out of Burdett Drive.
