We’ve been reporting on it for months, and, for the past week or two, publishing reminders almost daily – but better over-reminded than under-reminded – tomorrow is the day that the 1st Avenue South onramp to the westbound (high) West Seattle Bridge closes permanently, as part of the Spokane Street Viaduct Widening Project. SDOT says it will be closed first thing in the morning. It will be replaced by a new ramp to the westbound side of The Bridge, but SDOT says that will take at least 16 months to build. So if you’re trying to get to West Seattle from SODO, you will either have to use the “low bridge” detour – per the map on this page – or take the “back way” (head to the 1st Avenue South Bridge and enter West Seattle via Highland Park Way or Myers/Roxbury).
Remember that SDOT will use electronic signs and Twitter to warn of “low bridge” openings during rush hour, in hopes you will be forewarned if you’re heading to West Seattle that way; you don’t have to be a Twitter member to check out what SDOT posts at twitter.com/seattledot – that works as a regular weblink – but in case you lose the link, we’ve added it to the top of the WSB Traffic page. And also remember that bus routes are affected (Metro’s explanation here). If you use the low-bridge detour by car, bus or bike tomorrow, please consider sharing your story – any of these ways – about how it goes. One more reminder – for eastbound surface-street drivers in the area – as SDOT announced during the media tour we covered on Friday, lower S. Spokane Street will reopen by tomorrow morning, from East Marginal to 1st.
