Northwest Corridor (I-75) Express Lanes (GDOT)

The Georgia Department of Transportation 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 Road 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.

Construction began in October 2014 and is expected to be completed in summer 2018.
