Washington State Department of Transportation is anticipating having construction to begin on the two new roundabouts on SR 92 this spring with completion expected by early next year.
In December 2012, the State requested Design Build teams to submit qualifications and is expected to select a design team early this year. The design team typically consists of a contractor and engineer that will finalize the State’s existing concept plan and then implement the final design through completion.
The roundabouts are intended to improve safety by reducing the risk of high speed collisions and improve traffic movement at these two intersections in Lake Stevens.
According to the State, about 21,000 vehicles use the 99th Avenue NE intersection each day and approximately 16,500 at the 113th Avenue NE intersection.
Between 2006 to 2010 there were 17 collisions at 99th Avenue NE with five being injury collisions and 12 involved vehicles entering onto SR 92.
Over that same time period, the 113th Avenue NE intersection had 25 collisions including two injury accidents, 12 rear end type collisions and nine collisions involving drivers entering onto SR 92.
Roundabouts have been proven to significantly reduce the risk of injury collision and the two new roundabouts are anticipated to smooth out the flow of traffic and as a result reduce the risk of serious collisions on SR 92.
