Road closures underway for new $5M Cobb traffic project
Closures have begun for the $5 million Wade Green Road construction project over I-75.
There will be a single-lane closure on the bridge from Monday to Friday. The whole bridge will be closed from 9 p.m. Friday to 5 a.m. Monday and the same times the next weekend.
That section of the West Cobb artery will be transformed into a diverging diamond interchange — DDI — over I-75. The project was announced in June.
These types of traffic patterns shift traffic to the opposite side, making it easier to turn left onto an interstate.
The estimated cost is $5,046,495.07 with $2.07 million coming from federal funds, according to the transportation agency.
A portion of Windy Hill Road became a DDI earlier this year. The county posted a simulation online of how that traffic flow now works.
The intent is to get rid of crossing conflicts at ramp intersections and increase capacity without adding lanes, the agency said.
Crews will:
• Widen the southbound ramp onto I-75
• Reconstruct the westbound lane of Wade Green starting just east of where it meets the I-75 northbound ramp
• Add a right turn lane from the BP gas station for use by northbound I-75 traffic
• Add a left turn lane to the two westbound Wade Green lanes as they approach the I-75 northbound ramps
• Configure three West Green westbound lanes to cross the southern side of the existing bridge
• Add new sidewalks on both sides of Wade Green
