Sunday Bridge Series: a river (of paperwork) runs through it

A pedestrian bridge joins the two towers of the Ronald V. Dellums Federal Building.  Dellums is our former congressman and current mayor.  It has over a million square feet of office space, houses over 2000 workers, and was built to be as energy efficient as possible for the times.  It was a welcome addition to the skyline when built in 1993 and is easily spotted from afar.  It anchors a complex of government and private business office space collectively called City Center.  For a wide array of other bridges, visit «Louis'» meme Sunday Bridges.  Better yet, post a bridge of your own.
