Spokane Street Viaduct Widening Project
Until there is once again westbound access to the Spokane Street Viaduct from surface streets in SODO, southbound vehicles approaching Spokane on First Ave S will be detoured to the low level swing bridge to get to West Seattle. To reduce the expected congestion on this bridge during construction, SDOT has requested that marine vessels voluntarily provide advance notification when they will require the swing bridge to open, enabling drivers to plan accordingly.
When SDOT receives advance notification of a bridge opening expected during afternoon peak travel time (3 p.m. to 7 p.m. on weekdays), this opening will be announced on the electronic messaging signs now operating at Terminal 5 and at Fourth and Spokane. SDOT staff will also send the message with a specific time, if available, using Twitter (sign up to receive the Twitter messages at http://twitter.com/seattledot). The closure will also be posted on the Travelers Information Map on SDOT's website, http://www.seattle.gov/travelers
Alternative routes include:
South on 1st Ave S across the 1st Ave S Bridge, to W Marginal Way SW to West Seattle
South on 4th Ave S, left on S Michigan St to northbound I-5 to the West Seattle Bridge exit
1st Ave S or 4th Ave S north to Edgar Martinez ramp, to I-5 south to West Seattle exit, to S Spokane St Viaduct
For questions regarding how Metro Transit bus routes will be affected during this construction period, contact King County Metro Transit directly: by phone at (206) 553-3000; email at Customer.Comments@kingcounty.gov; or visit www.kingcounty.gov/metro for route information. Specifically, riders of routes 15, 18, 21, 22, 56, 57, 118, 119 are most likely to be directly impacted. If you would like to receive King County Metro e-mail route alerts, you may sign-up for them at http://metro.kingcounty.gov/up/rr/alertscenter.html.
Please note the primary detour route is a heavily used truck route serving industry in the Duwamish and the Port of Seattle's terminals. Many industrial and maritime businesses - and the thousands of jobs they support - depend on the corridor for the movement of goods.
Current Signed Detour route
The primary detour for vehicles approaching the construction zone will be signed. For through traffic heading westbound the route is:
Signals along these routes have been adjusted to reduce congestion, but greater congestion and slower transit times should be expected.
