Windy Hill Road lane closure at I-75 overpass to cause significant delays and congestion

Beginning Wednesday, Sept. 7, 2016, the right lane for eastbound travel on Windy Hill Road at the I-75 overpass will close indefinitely as the westbound lane on the north side of the bridge reopens. This 24-hour lane closure will cause significant traffic congestion and delays at different times throughout the day. Following this traffic shift, the lane configuration for eastbound traffic across the I-75 bridge will be two through lanes and one left turn lane to I-75 North. Construction work in the area will take place weekdays from 9 a.m. to 4 p.m. Drivers are strongly encouraged to use alternate routes.

The closure comes as part of continued work on the Windy Hill Diverging Diamond Interchange (DDI). Designed to increase capacity, decrease congestion and enhance safety at intersections while minimizing construction costs, the DDI will remove the existing left turn signals for vehicles accessing I-75, eliminating potential crossing conflicts between vehicles.

The DDI is one of five projects included in the $48 million traffic and safety improvements along a 1.43-mile stretch of Windy Hill Road, from U.S. 41/Cobb Parkway to Powers Ferry Road. Completion of the majority of the projects is expected in spring 2017.
