If you travel along NW 80th on Thursday, you may be detoured. Seattle Department of Transportation crews are taking advantage of spring break to work on NW 80th between 21st Ave NW and 22nd Ave NW. The crews will replace two concrete panels and plan to work from 9 a.m. to 5:30 p.m. Flaggers will assist westbound traffic past the construction area, while the eastbound traffic will be detoured at 24th Ave NW to NW 85th St. SDOT advises drivers to select alternate routes. The sidewalks will remain open during construction. If the weather is lousy, this project may be postponed.
