Traffic safety: roundabout construction starts

May 24, 2013

By Staff

Motorists should prepare for construction near West Lake Sammamish Parkway Southeast and Interstate 90 as the Washington State Department of Transportation (WSDOT) builds a new roundabout.

Crews recently started the safety project near the interstate on- and off-ramps at West Lake Sammamish Parkway Southeast and 180th Avenue Southeast. The project will wrap up by winter 2013.

The new roundabout will help make this intersection safer for drivers. More than 40 collisions occurred there over a four-year period.

The roundabout will help reduce the risk of serious collisions at the intersection by controlling the flow of traffic near the on- and off-ramps at West Lake Sammamish Parkway Southeast, and preventing traffic from backing up onto westbound I-90.

Roundabouts reduce the number and severity of collisions because they decrease the speed of traffic. Roundabouts also help keep traffic moving because drivers only have to yield to others, rather than stop.

The Department of Transportation offers more informationĀ for motorists and citizens interested in learning more about the project here.

    The FHWA has a video about modern roundabouts that is mostly accurate (http://www.youtube.com/watch?v=uhHzly_6lWM ).
    Modern roundabouts are the safest form of intersection in the world. Visit http://tinyurl.com/iihsRAB for FAQs and safety facts.
