We’ve been reporting on this for more than a year and a half, and now it’s about to intensify – day after tomorrow, a ramp and road closure kick in for the Spokane Street Viaduct Widening Project. The city’s sent out a reminder tonight as well as the detour map above – read on for the news release:
Work by the Seattle Department of Transportation (SDOT) to widen the South Spokane Street Viaduct – the 60-year-old elevated roadway that connects I-5 to the West Seattle Bridge – will have additional traffic impacts beginning Friday, January 22. SDOT’s contractor, PCL Construction Services, will begin construction near Fourth Ave S and S Spokane St that will necessitate the following ramp and lane closures (subject to change due to unforeseen circumstances):
* Permanently close the existing westbound Spokane Street Viaduct off-ramp to Fourth Ave S beginning Friday, January 22, at 10:00 p.m.
* Close the northbound I-5 off-ramp leading to the West Seattle Bridge for the weekend (10:00 p.m., Friday, January 22 through 5:00 a.m., Monday, January 25).
* Close the ramp from westbound Columbian Way leading to the West Seattle Bridge for the weekend (10:00 p.m., Friday, January 22 through 5:00 a.m., Monday, January 25).
* Close all lanes of westbound lower Spokane Street (from Sixth Ave S to First Ave S) to through traffic for the duration of the project beginning January 22. Local business access, however, will be preserved throughout the duration of the project.
* Close Fourth Ave S between S Horton and Industrial Way S to all traffic from 10:00 p.m., Friday, January 22 to 5:00 a.m., Saturday, January 23. Possible further restrictions as needed.
* Reduce Fourth Ave S between S Horton and Industrial Way S to one lane in each direction beginning January 22, and lasting for a minimum of one month. This may include full closure of northbound lanes at night for up to a week.
Due to the closure of westbound lower Spokane St and the westbound Fourth Avenue S off-ramp, traffic will be detoured on surface streets through the south of downtown area via the detour route shown on the enclosed map (see attachment). Drivers should expect congestion on I-5 near the Spokane Street Viaduct and in the SODO area Friday night through early Monday morning. This phase of the project should have minimal disruptions for King County Metro Transit bus service, but there could be delays if there is traffic congestion. In case of rain, crews will reschedule this weather-dependent work for the following weekend.
SDOT has several tools to help motorists get around during construction, which are outlined below:

SDOT Web site: http://www.seattle.gov/waytogo/wtg_sodo.htmWhen complete, the South Spokane Street Viaduct Widening project will nearly double
the width of the elevated roadway. Seattle commuters and the freight community will
enjoy improved access between I-5, SODO (the area south of downtown) and West
Seattle, and significantly improved traffic flow and safety on this key east-west
route. The $168 million viaduct effort, SDOT’s largest project currently in
construction, is expected to be complete by 2012.
