City of Dublin
Burgess & Niple (B&N) was selected to design a modern roundabout in Dublin, Ohio to reduce both the number and frequency of accidents at the intersection of Muirfield Drive and Brand Road.
The roundabout design incorporated aesthetic elements characteristic of the community infrastructure. The center island has undulating terrain with pot bunkers and low mounding to blend with the adjacent golf course. Uplighting and flagstones also are utilized. The roundabout pavement and approach legs are designed for expansion to handle increased traffic volumes in the future.
Roundabouts virtually eliminate right-angle collisions, which accounted for 75 percent of the accidents at Muirfield/Brand, and over 90 percent of the injury accidents. Modern roundabout designs reduce speeds to 25 mph or less through the circle, while providing greater capacity than a signalized intersection. Other advantages over signalized intersections include lower operation and maintenance costs and improved aesthetics.
In 2005, the Muirfield/Brand roundabout was named the Ohio Chapter of American Public Works Association’s (APWA) Project of the Year and was selected by the American Council of Engineering Companies (ACEC) for an Outstanding Achievement Award.
