The nice weather lately has kept the Washington State Department of Transportation (WSDOT) and the Seattle Department of Transportation (SDOT) busy, as both agencies scramble to complete projects before the fall rain soaks the region. Many projects rely on dry weather conditions and are postponed during wet weather conditions. Therefore, construction will be seen across Western Washington this weekend.
Bothell: I-405
In Bothell, up to three lanes will close Interstate 405 (I-405) south between State Route 522 (SR 522) and Northeast 160th Street.
Crews will shift traffic lanes for the I-405/Brickyard to SR 527 Improvement Project.
Construction will take place from 8 p.m. Friday to 8 p.m. Saturday.
Federal Way, Fife: I-5
Both directions of Interstate 5 (I-5) will close between State Route 18 (SR 18) and 54th Avenue East. Workers will set the remaining seven girders for the new SR 167 bridge over I-5, which is part of the SR 167 completion project.
This has a separate weekend closure — starting 10:30 p.m. Friday to 7 a.m. Saturday — and then starting 10:30 p.m. Saturday to 8 a.m. Sunday.
Detour routes include SR 99, SR 18, SR 161, SR 167 and SR 512.
Seattle: Ballard Bridge
Both directions of the Ballard Bridge will close for maintenance and preservation work from 10 p.m. Friday to 5 a.m. Monday.
