Those renderings by the Viaduct Preservation Group are leaning against the wall in a briefing room at Alaskan Way Viaduct and Seawall Replacement Program HQ in the Wells Fargo building downtown (3rd/Madison), where we are covering a briefing at which the Stakeholders Advisory Committee is going to get more information on why the idea of retrofitting The Viaduct is no longer under consideration (as announced when the options that ARE under consideration were unveiled June 26, listed here under “Step 4”). We’ll be summarizing this later along with the information we gathered the other night at the West Seattle open house for the South End Replacement project. The committee members who are here include West Seattleite Vlad Oustimovitch, who says he’d asked for a briefing like this to get a more detailed explanation on why retrofitting was ruled out. Here’s a summary of the studies analyzed as part of the process of reaching the retrofit-off-the-table conclusion.
