Cable-Stayed Bridges - Denver Millenium Bridge

On a cross country train trip, I was surprised to see this odd bridge at the Denver Railway Station. The tilted pylon dwarfs the pedestrian overpass that it supports. It has five cable-stays anchored into the ground and a dozen more supporting the 130 ft long concrete deck on tubular steel members.

They could have built this bridge without a tower by raising it up a step and deepening the superstructure. However, in that case they wouldn't have gotten this rather whimsical, Calatrava-like structure.

  1. I suspect the cables are doing more to stop the mast from falling over than to hold the bridge deck up.
