The Northwest Corridor Project express lanes designed to relieve traffic on I-75 and I-575 in Cobb and Cherokee counties are anticipated to be fully operational by the Labor Day weekend.
UPDATED: Northwest Corridor Lanes opening Saturday, Sept. 8
But now’s a good time to purchase the required passes for driving along the nearly 30 miles of managed lanes, which are nearly complete after more than five years of planning and construction.
That’s the message from Steven Lively, the Georgia Department of Transportation’s program delivery manager for major projects.
Earlier this week, he provided an update to the East Cobb Civic Association. While the general expected opening of the lanes is still “late summer,” he said “we hope to have traffic in the system by Labor Day.”
Resurfacing I-75 along the Express Lanes route, and on I-285 between the Chattahoochee River and Cobb Parkway is expected to be done by Aug. 31, he said.
The “Peach Pass” is currently being used on other managed lane and toll routes in Georgia, and will soon be expanded to the Northwest Corridor Project.
The pass is an electronic transponder device with an adhesive that sticks to a windshield or front bumper. Motorists purchase the passes in advance of their first time using the lanes, and then refill their accounts with money, depending on how much they use the lanes.
“We encourage people to use the system when it benefits them,” Lively said. “It may not be an everyday option but you get to make a choice.”
Motorists can apply online here to set up an account (for an initial fee of $20), and passes will be mailed. There’s also a mobile app for the Peach Pass.
The costs will be based on what’s called “dynamic pricing,” which rise as demand increases and is reduced during off-peak hours, Lively said.
He said toll charges for the Northwest Corridor routes will be set later by the State Road and Tollway Authority (SRTA).
Fines will apply to motorists who enter the lanes without a Peach Pass, or with one that’s expired, or if an account has insufficient funds, as well as for driving a vehicle that’s unregistered for Peach Pass use (more on fines here).
The finishing touches of the project, including testing of electronic signs and other devices at the interchanges, are underway now, according to Lively, who said the project is around 95 percent complete.
The $834 million project—the biggest in state transportation history—stretches in two lanes along I-75 from Akers Mill Road to Hickory Grove Road in Acworth. Three of the six interchanges will be easily accessible to East Cobb motorists: Akers Mill Road, Terrell Mill Road and Roswell Road.
The Express Lanes also include a spur at the I-75 junction that then goes up I-575 in a single lane to Sixes Road near Canton. Three sets of “slip ramps” include a northbound exit and a southbound entrance at Shallowford Road in Northeast Cobb.
The managed lanes will be for southbound traffic in the morning, and northbound traffic in the afternoon rush hour. Lively said the express lanes will be closed for three hours in between to clear vehicles and reverse the direction of the traffic flow.
Georgia DOT estimates that the Express Lanes can ultimately save motorists up to 43 minutes on their daily commute time, depending on how long their travel is on that route, and that drivers in the general lanes could have their traffic time reduced by as much as 16 minutes.
