MARYSVILLE – With the forecast quickly changing, work on the single-lane roundabout at Highway 9 and 108th Street NE in Marysville will be suspended later this month. During a weekend closure in late September, contractor crews working for the state Department of Transportation were able to prepare the intersection for the heavy lift needed to complete the safety improvement project.
Crews were able to:
•Ground down a 4-foot hill blocking eastbound travelers’ view of the intersection.
•Complete paving on the west side approach of 108th Street NE.
•Installed drainage pipes and culverts along both sides of Highway 9, under 108th Street NE.
•Widened and paved all four corners of the intersection in preparation for roundabout installation.
The project will likely resume spring 2020 when dry weather returns. At that time, the second weekend closure for installation of the roundabout will be scheduled. Roundabouts have a proven record of reducing injury collisions by 75%. Right now, nearly 10% of the 16,000 drivers who use this intersection every day are attempting turns from the stop signs at 108th Street NE onto Highway 9, increasing the risk of collision. The new roundabout will reduce this risk as well as wait times at the intersection.
