The Norcross Street and Warsaw Road intersection with Grimes Bridge Road and Melody Lane in Roswell, Georgia, had become a nightmare for drivers – a focal point of confusion, frustration and danger. The existing signalized intersection shuffled approximately 28,000 vehicles every day and with only one dedicated left-turn lane, drivers experienced lengthy delays during peak hours and the number of crashes had increased significantly over the years. The City of Roswell was aware of the strain the intersection had placed on the community and hired Gresham Smith to develop a plan to control and direct the traffic. Our final design solution was a single-lane, five-legged roundabout. Formerly one of the top locations for crashes in the city, the award-winning roundabout at Grimes Bridge Road is a huge improvement over the former hazardous intersection and has received overwhelmingly positive feedback from the community.
