Project Description:
This project begins on I-75 where the current HOV system ends at Akers Mill Road. It will be two bi-directional lanes, one lane in each direction, from Akers Mill to I-285. At I-285, the project will construct two reversible managed lanes on west side of I-75 between I-285 and I-575, adjacent to the southbound lanes. Near the I-575 interchange the managed lanes will move to the median. One lane will continue north on I-75 to north of Hickory Groove Road. One lane will continue north on I-575 to Sixes Road. System will be barrier separated and access points on I-75 will be provided which will not interfere with general purpose interchange operation. I-575 will have slip ramps to or from GP lanes. The operation of the manage lanes will be tolled to improve effectiveness. Access points on I-75 will be provided at I-285, Terrell Mill, Roswell Road, I-575, Big Shanty and Hickory Grove. The project length is 16.8 miles on I-75, 11.3 miles on I-575 and 1.6 miles on I-285.
