Some really cool bridges so far, keep em coming!
This one in Vancouver was always one of my favourites. It crosses 5 lanes of traffic and a railroad track, yet the bushes on either side are so tall you don't even notice you've left the park until you end up on 7th Ave.

This is the view from the middle of the overpass, the first time I went over it I never even knew I had left solid ground.
