Windy Hill Corridor

Innovating One Of Cumberland's Busiest Highways

Windy Hill Road serves as a major artery in Cumberland, connecting West Cobb to the heart of Cobb’s employment center. In the late 1980/90s, Windy Hill Road became a bustling corridor with safety and traffic concerns arising.

Due to those concerns, the Cumberland CID and Cobb County came up with an innovative solution. A $48 million project that featured a diverging diamond interchange (DDI), one of the first in Georgia and key road widenings east and west of the Windy Hill Bridge.

Improving Traffic Efficiency

The improvements along with the road widenings allowed the corridor to handle additional capacity and installed new medians for safer travel.

The DDI allowed the Windy Hill Bridge to be reconfigured which eliminated the left hand turns at traffic signals. This has improved traffic flow without the addition of extra lanes.
