Replacing a traditional intersection with a roundabout can reduce the number of crashes by 35 percent. Even more impressive: roundabouts bring the number of fatalities down by 90 percent!
At SCJ, we’ve been doing roundabouts for a long time. Senior Principal Perry Shea designed Washington’s first state route roundabout in 1998. Since then, our team has completed various stages of analysis, design, and construction for more than 50 roundabout intersections in Washington, Oregon, and Alaska.
Currently, Principal Scott Sawyer and his team are working on a series of three roundabouts in a high-traffic area of Tumwater. Here, it’s not just about safety, it’s also about traffic flow.
“Roundabouts perform better than a signal in keeping vehicles moving, especially during off-peak hours,” Scott said. “When it isn’t rush hour, the roundabout is always moving, as opposed to having to randomly wait at a red light.”
Earlier this year, we welcomed national roundabout expert, Brad Shea, to the team.
“Brad’s breadth of experience and depth of knowledge about roundabouts is second to none,” said SCJ Principal Amy Head. “He’s led projects across the country, into Canada and in our own backyard.”
Right now, Brad is working on the City of Aberdeen’s first roundabout and multiple roundabouts in Thurston County. Additionally, more far flung, is a project for Valley Metro in Arizona, where we’re evaluating incorporating light-rail through the middle of a roundabout – a first for the United States.
