The Georgia Department of Transportation has announced that lanes on GA 400 at exit 13 will be closed on Monday and Tuesday of this week (March 3 and 4).  These lane closures are due to the road widening project on Highway 141 (Peachtree Parkway).  Parts of the bridge that cross GA 400 are being removed.  The lane closures will occur between the hours of 9:30 a.m. and 3:00 p.m.   Use extreme caution while traveling in this area.
