GA DOT gives official nod to $800 million I-285/SR 400 interchange project
Field survey work on Atlanta’s I-285/SR 400 Interchange Project began the same day the Georgia Department of Transportation (GDOT) issued the Notice to Proceed. The interchange project includes four miles of improvements on I-285, fives miles of improvements on SR 400, new flyovers, new connections, a bridge replacement, and several other features. The $800 million design-build (D/B) and finance contract was awarded to North Premier Contractors. Completion of the project is expected in 2020.
