The Seattle Department of Transportation (SDOT) will close the Spokane Street viaduct overnight for three nights for work related to the Spokane Viaduct Widening.
Eastbound lanes of the viaduct (West Seattle Bridge) will be closed from 11 p.m. February 25 until 5 a.m. February 26 to evaluate the pavement condition. During this closure all eastbound traffic will be prohibited east of the First Avenue off-ramp, which will remain open, as will the northbound SR 99 ramp. Traffic heading to I-5 should plan on using lower Spokane Street.
The westbound lanes of the Spokane Street viaduct will be closed overnight on February 27 and 28 from 10 p.m. until 5 a.m. the following day to remove portions of the old structure. During this closure, southbound I-5 traffic will be directed to the Forest Street exit to access surface streets. Northbound I-5 traffic and westbound traffic from Columbian Way will be detoured to surface streets at 6th Avenue South.
Also beginning February 25, Sixth Avenue will be reduced to one lane in each direction for continued work underneath the viaduct. Meanwhile, the work on Fourth Avenue South is expected to wrap up in March, after which all lanes will be open for use and only occasional lane closures are expected.
