The project included constructing a roundabout at the intersection of Route PP and Township Line Road in Poplar Bluff.
The roundabout helps traffic flow more smoothly in addition to improving safety. Roundabouts have fewer conflict points, or spots where vehicles could collide, than signalized intersections. The reduced number of conflict points, combined with slower speeds and calmer traffic, has been found to reduce the number of severe crashes. Severe crashes typically occur with broadside (Tbone) or head on collisions.
