In theory, I like the idea of eliminating the overpass. But I don't think it's practical on the kind of timeline we'd like. We have not done remotely enough work to eliminate car dependence. And this bridge is a pretty crucial link for car based travel. I mostly bike or take the T, but right now, we are still stuck with too large a population for which such modes do not work. Without Bowker, cars will detour on to Boylston and Mass Ave., or Park Drive and Beacon St., making traffic worse. I think we have to acknowledge this in thinking about how to address this location. Like it or not, Storrow is still going to be here for a couple of decades, and there will be large numbers of people needing access via the Bowker.
