SR 9 - 32nd Street S.E. - Roundabout

Why is WSDOT building a roundabout at the SR 9/32nd Street S.E. intersection near Lake Stevens?
We will build a two-lane roundabout to help improve traffic flow and help reduce the risk of serious collisions at SR 9 and 32nd Street S.E. About 19,000 vehicles use this stretch of SR 9 each day. The SR 9/32nd Street S.E. intersection was the site of 14 collisions from 2006 to 2010, including one serious injury collision. There were three rear-end collisions and four collisions involving drivers entering SR 9 from 32nd Street S.E. 

The End Result
Drivers will benefit from a smoother flow of traffic and a reduced risk of serious collisions at SR 9 and 32nd Street S.E. Roundabouts are designed to make intersections safer and more efficient for drivers, pedestrians and cyclists. Roundabouts have been proven to significantly reduce the risk of injury collisions.

Project Benefits

Roundabouts help reduce the likelihood and severity of collisions:

• Low travel speeds – Drivers must slow down and yield to traffic before entering a roundabout. Travel speeds in a roundabout are typically between 15 and 20 miles per hour. The few collisions that occur in roundabouts are typically minor and cause few injuries since they occur at such low speeds.
• No light to beat – Roundabouts are designed to promote a continuous, circular flow of traffic. Drivers need only yield to traffic before entering a roundabout; if there is no traffic in the roundabout, drivers are not required to stop. Because traffic is constantly flowing through the intersection, drivers don't have the incentive to speed up to try and "beat the light," like they might at a traditional intersection.
• One-way travel – Roads entering a roundabout are gently curved to direct drivers into the intersection and help them travel counterclockwise around the roundabout. The curved roads and one-way travel around the roundabout reduce the risk of T-bone and head-on collisions.

What is the project timeline?
This project will be built using the design-build process. We are currently revising our schedule. We expect to award the contract to a qualified design-build team in 2013 and begin construction in 2014.
