Accura is providing geotechnical design support services to AECOM for this Georgia DOT MMIP project. State Route 400 (SR 400) is a vital north-south transportation corridor in metro Atlanta that connects people, jobs, and freight. To improve mobility, Georgia DOT plans to add new, optional express lanes from the North Springs MARTA Station to McFarland Parkway. The project will add:
- 2 buffer-separated express lanes in each direction between the North Springs MARTA Station and McGinnis Ferry Road
- One buffer-separated exprers lane in each direction from McGinnis Ferry Road to McFarland Parkway
