• Abstract:
  Roundabouts are a special type of intersection that ensures continuous vehicle movement while maintaining slow and safe speeds. Many state departments of transportation are converting existing intersections into roundabouts, but roundabout construction can create significant traffic closures and disruptions. Thus, accelerated construction can be very beneficial in places where extended traffic closure is not practical or possible. Using precast concrete panels in roundabout construction can shorten closure times and create less disruption for the traveling public.
