Kirkwood Blvd Roundabout
A new roundabout has been constructed at the intersection of Kirkwood Blvd and the Prairie Point Middle School entrance, and has opened ahead of schedule. The roundabout will help improve safety and traffic flow during peak morning and afternoon hours. Download the project FAQ for additional information. 

Video Simulation of Kirkwood Blvd roundabout

The video below illustrates a typical morning commute at the College Community School District. This simulation video is showing average traffic counts that are experienced during the morning drop-off period. 

Navigating a Roundabout

Slow down as you are approaching the roundabout. Yield to pedestrians in the crosswalk

Yield to vehicles in the roundabout. Wait for a gap in traffic, and merge into traffic in the roundabout in a counterclockwise direction.

Continue through the roundabout until you reach your street. Never stop in the roundabout.

Exit the roundabout to your right. Yield to pedestrians in the crosswalk.

What is a Roundabout?

A modern roundabout is an unsignalized, circular intersection engineered to maximize safety and minimize traffic delay. Fundamental characteristics of all roundabouts include:

  • Counterclockwise Flow. Traffic travels counterclockwise around a center island
  • Entry Yield Control. Vehicles entering the roundabout yield to traffic already circulating.
  • Low Speed. Curvature that results in lower vehicle speeds, generally 15-25 MPH, throughout the roundabout

Benefits of Roundabouts


  • Eliminates head-on crashes and right-angle crashes
  • Decreases severity of crashes
  • Reduces speeds 


  • Can move more traffic during peak hours
  • Reduces stops
  • Reduces delays
  • Reduces congestion 


  • Reduced emissions
  • Reduced fuel waste
  • Fewer hard stops
  • Landscaping and beautification / neighborhood aesthetics 


  • Longer service life
  • No signal maintenance 
  • Better long-term economic value
