The Georgia Department of Transportation (GDOT) broke ground Sept. 17 on an $834 million project that will create 30 miles of dedicated managed toll lanes on I-75 and I-575 in Cobb and Cherokee counties. Construction will commence at four separate locations next month.
GDOT is teaming up with Northwest Express Roadbuilders in a public-private partnership (P3) on the Northwest Corridor express lanes project. I-75 and I-575 are two of the state’s busiest roadways, and the department hopes to improve traffic flow in the Atlanta metro region. A pair of reversible lanes will be implemented just west of I-75 between I-285 and I-575, directing traffic south in the morning and north in the evening. Single reversible lanes will be installed on I-75 and I-575 north of where the two roadways meet and diverge.
The Northwest Corridor lanes will utilize the Peach Pass transponder system already in place. Six new I-75 exits will provide access to the toll lanes, as well as three slip-ramp access points.
Northwest Corridor lanes should be open to traffic by 2018.
