Rivertown Road at Cedar Grove Road Intersection

The Transportation Division of the Fulton County Department of Public Works has contracted with American Engineers, Inc. to design the operational and safety improvements for the Feldwood Road at Bench Mark Drive, Rivertown Road at Cedar Grove Road, and Stonewall Tell Road at Union Road intersections. All three projects are funded through TSPLOST and are currently in the conceptual design phase.
County: Fulton
Project: Rivertown Road at Cedar Grove Road Intersection Improvement Project
Description: Proposed solutions to resolve the safety and operation concerns for this Rivertown Road at Cedar Grove Road Intersection consist of two alternates. Alternate 1 is to construct a roundabout that is ADA compliance with sidewalks and crosswalks, and will contain lighting. Alternate 2 is to realign Cedar Grove Road to the west by about 250-ft. with a 90-degree skew, lower the Rivertown Road hill by about 2-ft. to provide vertical sight distance, install a conventional intersection at this location with dedicated left and right turn lanes, and provide pedestrian facilities. Alternate 1 is more economical than alternate 2 and right-of-way acquisition is less for alternate 1 as well.
