"The new I-85 Express Lanes Extension will improve traffic flow and increase mobility options for people who travel the area, including motorists, transit and registered vanpool customers," Georgia Department of Transportation Deputy Commissioner Mike Dover said in a news release. "This project addresses one of the region's most congested commuter corridors."
In addition to the new express lanes, work will include building "auxiliary" lanes at Ga. 20 northbound and Gravel Springs Road and at Ga. 20 southbound and Lawrenceville-Suwanee Road. An express lane bridge will be built at the northbound interchange of I-85 and I-985 as well.
The project is expected to be completed by summer 2018. Work will take place during non-peak hours.
The existing I-85 HOT lanesopened in 2011 and run 16 miles from northern Gwinnett to DeKalb County. Their construction rankled many commuters who either didn't want to pay or were upset they replaced the already-existing HOV lanes.
