[ARCHIVED] Traffic Safety: Roundabout Construction Starts

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.

Why roundabouts? They reduce the number and severity of collisions because people drive more slowly through a roundabout. Roundabouts also help keep traffic moving because drivers only have to yield to others, rather than stop.

WSDOT offers more information for motorists and citizens interested in learning more about the project.
