OSO – The Washington State Department of Transportation and its contractor, Atkinson Construction, have listened to community concerns and rescheduled the Wednesday, Sept. 3, State Route 530 detour to avoid affecting traffic on the first day of school.

Contractor crews now plan to detour SR 530 traffic to the Seattle City Light access road for one full weekend starting at 9 p.m. Friday, Sept. 5. The closure will allow for the installation of a 19 foot-wide, by 50 foot-long concrete culvert underneath the new roadway to help manage water from a stream headed to the Stillaguamish River. Contractor crews will also continue work on building the new, elevated west section of the highway.

“Scheduling the detours to rebuild SR 530 is a balancing act for everyone involved,” said WSDOT Regional Administrator Lorena Eng. “We strive to take into account the needs of the community, drivers and the contractor with the goal of completing the project before the fall weather sets in.”

Currently scheduled SR 530 detours

  • 9 p.m. Friday, Sept. 5 to 4 a.m. Monday, Sept. 8.
  • 9 p.m. Tuesday, Sept. 9 to 4 a.m. Thursday, Sept. 11.
  • Scheduled detours may be cancelled because of weather and construction schedule changes.

The majority of the work to reconstruct SR 530 is expected to be completed by early October. The project is being built with $28.1 million of Federal Emergency Relief funding.
