Does your city have any streetwalls along expy's/fwy's?

Does your city have any street walls directly facing its downtown area? I'm speaking of those stretches that directly parallel a rather solid wall of high rise buildings? I'd have to say the best (and best known) of these currently can be found on the LA freeway system. On the Chicago forum, we have been talking about one developing on the Kennedy Expressway, west of the Loop. Boston, of course, exprerienced such a street wall prior to the Big Dig. If you have any pictures of such a streetwall-on-the-expressway, we'd love to see them.>
