   [1]Flash at Centrisity ponders what [2]the next I-35W bridge might
   look like, complete with pictures of a comparable structure near
   Boston. The "Planning Class" is already twittering about bike paths,
   local art, even light rail tracks. Engineers both real and imagined
   speak of redundancy and maintainability. Nick Coleman will want a
   digital readout showing today's odds making it to the other side,
   flashing red when the temperature reaches 90 degrees.
   We should indeed take the time to do this right, if for no other
   reason than it is our state's busiest bridge. The old one was eight
   lanes I believe, and that probably wasn't enough. I wonder if two
   spans aren't required, one each way, with abundant shoulders either
   side. That would allow maintenance and inspections to be less
   disruptive.
   One span could also provide the walking / biking path, which seems
   like a reasonably cheap add on. The other, yes, could carry train
   traffic, be it Northstar and/or Central Corridor. (Sorry, I'm
   suffering from inevitability this week.)
   The only other detail is where to put the Sayles-Belton Memorial Art
   Supply store.
