We will widen SR 9 from SR 524 (212th St SE or Maltby Road) north of Bothell to 176th St SE in Clearview.
All lanes of SR 9 will close from 9 p.m. Aug. 10 to 2 a.m. Aug. 12 as crews install a culvert beneath SR 9 near 188th St. Drivers will follow a signed detour.
During construction, bicyclists will follow a marked detour around the work zone. To ensure the safety of riders, cyclists will not be allowed to cross SR 9 in the work zone.
