The Northwest Corridor project will improve travel in the I-75/I-575
corridor by adding 29.7 miles of toll lanes along I-75 from Akers Mill
Rd to Hickory Grove Road and along I-575 from I-75 to Sixes Road. Two
Express lanes will be built to the west of the existing lanes along I-75
between I-285 and I-575. From that interchange, one express lane will
be added along I-75 north to Hickory Grove Road and one express lane
will be added along I-575 to Sixes Road.
