Chanting “save our bridge,” shaking noisemakers, waving pom-poms, and drawing honks from passing drivers, dozens of people concerned about the upcoming permanent closure of the South Park Bridge lined its southern half for a while this afternoon. They were hoping to be seen by some of the politicians who were on their way to South Park for a rally celebrating the recently signed federal health-care legislation (separate story on that event coming up). We don’t know if they were indeed seen; shortly after we shot that video, it started to rain – hard – and some of the participants left (though we did notice some staying, undaunted, with umbrellas). The bridge closure is set for 7 pm June 30th; last week, reps from multiple agencies were summoned to start talking about coordination of resulting traffic and public-safety issues (WSB coverage here), while the highlight of the funding search was the Seattle City Council‘s declaration it would support the county’s quest for money (WSB coverage here). ADDED 10:55 PM: Noemie Maxwell has posted her story about today’s rally on Washblog, with lots of photos – see it here.
