Meet the Oblong Roundabout at the I-405 / NE 85th Street Interchange

Published on May 15, 2026

The new oblong roundabout at the I-405 / NE 85th Street interchange isn't as intimidating as you might think! Join us for a Roundabout Ride Along!

Watch our Roundabout Ride Along: Safety 101 video.

Here’s how to keep yourself, other drivers, bikers, and pedestrians safe while driving in multilane roundabouts:

• Choose the appropriate lane based on the lane assignment signs. 
• If there’s a crosswalk, be prepared to stop for pedestrians before entering the roundabout. 
• Look to your left and yield to drivers already in the roundabout. You don’t have to stop if there’s a gap in traffic. 
• Stay in your lane and let the pavement markings guide you. 
• Be courteous and use your right turn signal to indicate your exit to the vehicles around you. 
• If there is a crosswalk, be prepared to stop for pedestrians when exiting the roundabout.
