It’s been a while since this was announced – but tomorrow’s the first night, so SDOT is out with a reminder today:
Work to widen the Spokane St Viaduct requires closure of the structure’s westbound lanes just west of I-5 for six nights: from 10 p.m. – 5 a.m. this week and next on Wednesday , Thursday and Friday nights – January 19, 20, 21, and 24, 25, 26. During the closures, the bridge weight will be shifted onto a new column; a barrier will be set up on the Harbor Is. ramp; and pavement repair needs will be determined. No work is scheduled and all lanes will be open Saturday and Sunday nights. During this work, southbound I-5 traffic will exit at Forest St to access surface streets. Northbound I-5 traffic and westbound traffic from Columbian Way will be detoured to surface streets at 6th Ave S.
The Spokane Street Viaduct is the section of the West Seattle Bridge between Highway 99 and I-5.
