The roundabout at Ohio Drive and Warren Parkway opened to traffic April 9. The multilane roundabout replaced the stop signs at the four-way intersection, so drivers can now continuously move through it. Two other roundabouts on Ohio Drive are in the planning stages: one at Wade Boulevard and one at Gaylord Parkway.
