Assuming weather allows, GDOT will begin clearing construction areas for the project at Ga. 400 (between Windward Parkway and Peachtree Parkway) and McGinnis Ferry Road in the Alpharetta area this week.
Crews with C. W. Matthews Contracting Company, Inc. of Marietta will begin clearing construction areas for the project on Ga. 400 (between Windward Parkway and Peachtree Parkway) and McGinnis Ferry Road (between Deerfield Avenue and Counselors Way).
The project plans to widen 1.534 miles and construct interchange improvements, including the construction of a full diamond interchange on Ga. 400 at McGinnis Ferry Road, construction of a bridge and approaches over Ga.400 and the installation of Intersection Video Detection Systems (VDS) in Forsyth and Fulton counties.
The full diamond Interchange will allow traffic to cross to the opposite side on both sides of the bridge, allowing free-flowing left turns onto Ga. 400. This will eliminate traffic back-ups in the left-turn lanes at the signals, accommodating the high left-turn volume but with fewer lanes.
The entire project is anticipated to be complete in spring, 2024.
