Roundabout construction starts
May 28, 2013
Motorists should prepare for construction near West Lake Sammamish Parkway Southeast and Interstate 90 as the Washington State Department of Transportation 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, according to a press release from the city. The project will wrap up by this winter.
The new roundabout will help make the intersection safer for drivers, according to the city. More than 40 collisions occurred there in 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, the city said in the release.
Roundabouts reduce the number and severity of collisions by decreasing the speed of traffic. Roundabouts also help keep traffic moving since drivers yield to others rather than stop.
