Windy Hill-Terrell Mill Connector

As Cobb County continues to grow in population, educational opportunities, professional prospects and recreational options, it is vitally important that our roadways develop and expand to support that progress. One of our fastest-growing areas, Cumberland, will soon serve as an even greater hub for sports, music and culinary enthusiasts with the addition of SunTrust Park and The Battery in 2017. However, plans for facilitating increased travel in Cobb have been in the works for years—a decade or more in some cases—long before the county became the new home for the Braves.

One such long-planned project is the Windy Hill – Terrell Mill Connector, a proposed extension of Bentley Road. The new four-lane road will begin at the intersection of Spectrum Circle/Interstate North Parkway and Windy Hill Road and connect at the current Bentley Road and Terrell Mill Road intersection. This project will serve as a reliever for Powers Ferry Road by absorbing traffic normally traveling that route to and from Windy Hill Road and Terrell Mill Road. With the addition of a landscaped median, multi-use trail, sidewalk and lighting, the road will be an excellent new travel option that connects to the Bob Callan Trail System and provides a congestion-alleviating alternative access route to the future I-75 Northwest Corridor Express Lanes.
