ATLANTA — It may seem intimidating at first, but the Georgia Department of Transportation says the seventh diverging diamond interchange in the state will help improve traffic flow.
GDOT contractors opened the Camp Creek Parkway DDI bridge Sunday night at I-285 ahead of schedule, following a complete shutdown of the intersection this weekend, they said.
The DDI configuration is designed to reduce driver turn movements to access and leave the interstate and reduce traffic back-ups and delays. Nationally, GDOT says, DDIs have proven to be cost-effective, quick-delivery ways to address congestion for high-traffic interstate access points.
Contractors closed the Camp Creek Parkway bridge on Friday night over I-285 to traffic in order to complete the permanent striping of the new DDI lane configuration, check traffic signals and perform other work.
Contractors will continue work on the pedestrian sidewalk in the center of the bridge, they said. Motorists will see cones and barrels on the bridge until the work is completed.
Officials encourage motorists to drive slowly and pay attention while navigating through the new lane configuration. In addition, police officers will be located on the bridge to assist motorists during the transition.
Other DDI bridges in the metro Atlanta include one at I-285 at Ashford-Dunwoody, I-85 at Jimmy Carter Boulevard and I-85 at Pleasant Hill.
The project included widening the existing bridge, adding the pedestrian sidewalk in a newly constructed median, resurfacing the roadway, installing new traffic signal equipment, and making improvements to the bridge, they said. The overall completion date is set for May 2020.
