Well, I've pretty much blown today on trying to model a mockup of the Golden Gate Bridge. According to the world fiction, this should be destroyed and San Francisco should be a partially submerged aquatic arcology... but what the hey...! I decided to again exploit Wings3d's new bend feature. This time, I wanted to see if I could recreate the bow the of span and the cabling. Months ago, I tried without this feature and found that trying to make curves from straight objects was murder!
It's technically not complete (I didn't finish end span details because I got bored). I also went nuts and used a few selection tricks to do all the cabling as well as the X-bar girders along part of the span itself. I think the cabling, which amounts to triangles, and the X-bars along the midspan would instead be done with textures. At 25,564 polys total (triangulated), those details are extremely costly-- but it might not matter if it was for a full level you could walk and drive across.
