West Seattle Transportation Tangle: A linear look

timeline.jpg


Click that image for a larger look at the helpful chart drawn up by Morgan Community Association’s Cindi Barker after last night’s West Seattle Chamber of Commerce-sponsored transportation forum: She drew lines for each of the major projects likely to affect West Seattle drivers – BEFORE the Alaskan Way Viaduct‘s Central Waterfront Project starts in 2012 – so you can see where they overlap, at least under current plans. (Remember, the next big thing to kick in is the closure of lower eastbound Spokane Street, starting Tuesday 9/16, for water-main work preparing for the Spokane Street Viaduct Widening Project – that means if you get off the eastbound SSV on 1st Avenue South, you will have to turn left; if you are on eastbound Spokane Street from points further west, you will be able to turn right on 1st – no one will be allowed to go straight ahead on eastbound Spokane from there except truly “local” traffic, such as deliveries.

    What is the “Lower Spokane St Duwamish Bridge rehabilitation”? Sound like it has the potential for significant impact to those of who commute to downtown by bicycle via the lower bridge.

    I still don’t understand why when exiting from eastbound Spokane viaduct onto 1st and being in the right lane, one can’t turn right. The further west Spokane traffic under the Viaduct can’t go strait and there are three lanes on 1st. So Spokane traffic could stay in the two right lanes of 1st and the Viaduct exiting traffic could take the far left lane. This could make a huge difference in the detour.

    I also have no idea what the Duwamish Bridge Rehab is, read nothing about it. Nor about the 2008 E. Marginal Grade Separation – what is that all about? What are the street boundaries for these two projects and how are they going to effect ALL traffic?

    Is the Marginal Grade separation a part of “Stage 1?”

    Pgs 93-94: “During Stage 1, pedestrians and bicyclists would use the existing combined path south of Atlantic St. Between S. Atlantic & S. Royal Brougham, the path would cross under the existing viaduct and run along a temporary path east of the viaduct. North of S. Royal Brougham, the sidewalk on the west side of Alaskan would be closed and peds and bikes would be routed along the existing MUP. Signs would be posted to help direct peds and bikes through the construction zone.

    During the last 6 mos of Stage 1, bikes using the bike lane on Alaskan could be detoured, as will vehicular traffic to Atlantic, Royal Brougham, and 1st Ave S. Bikes would have the option of sharing the road with vehicles on the detour routes or using the existing MUP on the east side of Alaskan.

    I found just a couple snippets from general Alaskan Viaduct construction materials regarding the Grade Separation. Can’t confirm it’s part of “Stage 1” but it does involve starting to work on improving freight and general purpose traffic flow to Port/waterfront/stadiums…most likely around Royal Braugham/Atlantic and involving overpass preparation there…but it also could involve seawall repair. I cannot find anything so far about the Duwamish Bridge work.
