New section of Ga. 400 southbound opens Friday
Ga. 400 construction

Drivers who take Ga. 400 southbound are getting some traffic relief.

On Friday, the southbound side of Ga. 400 will open its new widened portion from Exit 13 at Peachtree  Parkway (Hwy. 141) to Exit 12 at McFarland Parkway. The new portion is about four miles, and work began in May.

The next phase — Exit 14 to the intersection with Browns Bridge Road (Hwy. 369) — is expected to open in late spring 2018. 

The intersection will be the future Exit 18 as a new “partial cloverleaf” interchange.

Construction is slated to begin in 2018 and will take about 36 months. The estimated cost of the project for construction, acquiring right of way and utilities is about $47 million. Forsyth County is putting forth $33 million.

Bridges over Big Creek and Sawnee Creek will need to be widened. 

The total widening project is to be completed by fall 2018. 

In June, the final section of the new lane on Ga. 400 northbound opens to drivers. 

The Georgia Department of Transportation contributed about $13 million to the project, and Forsyth County has funded around $34.5 million, which came from the $200 million transportation bond approved by voters in 2014.
