Speaking

In Washington state, the state Department of Transportation and local agencies have been building roundabouts since 1997, and as of Summer 2024, there are approximately 600 roundabouts. Roundabouts represent safety investment and, in many cases, deliver delay reduction and better access management. Context plays a significant role in how large or complex a roundabout might be. The presentation will touch on all these key decision points and present examples that show the process of conceiving, planning, designing, building, and operating a roundabout. It will share important lessons learned and, importantly, how the right tools are used to deliver a roundabout that functions and is right-sized for the context.
