GDOT will assist Cobb County to construct a diverging diamond interchange at Interstate 75 and Wade Green Road.
A diverging diamond interchange (DDI) is an intersection traffic solution designed to increase capacity, decrease congestion and minimize cost. The DDI is designed to ease the flow of heavy traffic by eliminating a left turn signal and allowing two-directions of traffic to cross the opposite side of the side or cross street at or near the bridge point over the freeway.
Cobb County will be responsible for completing and funding the preliminary engineering and right-of-way costs for the project.
Once completed, GDOT will fund up to $1 million of construction costs from their operational improvement lump sum. The rest of the $1.625 million cost will come from Cobb County SPLOST funds.
