SR 9/SR 204 Intersection Improvements – Roundabout information

Why roundabouts?

Roundabouts are designed to be safer than traditional intersections for drivers, pedestrians, and bicyclists. This safety aspects include slower speeds, crosswalks that are set back further away from intersecting traffic, and islands between lanes for a safe wait place. As traffic volumes increase on local roadways traditional intersections using stoplights can increase delays for drivers. Transportation departments around the nation are more frequently turning to roundabouts as an efficient, cost-effective way to improve safety and traffic flow.

The new SR 9/SR 204 intersection design will improve traffic flow, trip reliability, freight movement, safety, and access to local businesses by diffusing traffic across the four roundabouts. The project also improves transportation connections by increasing travel options for pedestrians, bicyclists, transit riders, and drivers.

Navigating roundabouts

Read through the helpful tips below to learn how to safely navigate the new roundabouts about the SR 9/SR 204 intersection.

  • Slow down when approaching the roundabout
    Intersection warning signs let drivers know there is a roundabout ahead. Roundabouts are designed for speeds between 15 and 25 mph.
  • Pick a lane as you approach the roundabout
    The lane choice sign shows drivers which lanes are used for right turns, straight through travel, and left turns. Once you pick a lane, stay in that lane until you exit the roundabout.
  • Yield to pedestrians and bicyclists in crosswalks
    Yield to pedestrians and bicyclists in marked crosswalks when you enter and exit the roundabout.
  • Yield to all traffic in the roundabout
    Look left to all traffic already in the roundabout, they have the right-of-way.
  • Exit at the street you want
    Once you see a gap in traffic, enter the circle to the right and proceed to the exit moving counterclockwise.
  • Emergency vehicles
    If an emergency vehicle approaches, drive through the roundabout and pull over, just like you would at any other intersection. Do not stop in the roundabout.
  • Give trucks space
    Large vehicles need a lot of space and are allowed to use both lanes, so remember to never drive next to large vehicles in a roundabout.
