Here's a proposed design for a new giant bridge across Copenhagen's harbor, by Danish architects LXM. Besides looking cool and space-age, the lightweight design would be both a bridge and a "city gate," with swooshy lines reminiscent of the water it flows over. Too bad 3XM lost out to a clunkier design from Steven Holl Architects. A few more sexy 3XM pics below.
