Sweet Sunny Italian Train

Very cool people-mover/ped. walkway/solar field in Bologna.

" . . .designed to speedily move people from the main train station in Bologna out to the airport with only one intermediate stop at Lazzaretto. It crosses over one major highway, spanning the stretch of road in a graceful arc. At each station a metal screen covered in vegetation protects passengers from the elements, and also helps filter the air, provide natural insulation and shade the platform."

Or they could all just drive separately and park in huge asphalt lots.
