Interstate 285 & Riverside Dr.

Atlanta, GA

MTJ reviewed the proposed designs for both roundabouts for operations and safety.

We designed a highly developed concept for horizontal geometric recommendations and vertical/grading recommendations for the northerly most roundabout (WB off ramp), and horizontal design modifications for the EB ramp roundabout to promote consistency in design application between these two closely spaced roundabouts.

We completed an operational and horizontal review for both roundabouts and developed the essential minimal recommendations to provide optimal safety and improve operations.
