I'm looking for something like this, but just an empty bridge without any people (it doesn't have to be that exact cross-section of the bridge, but I'm looking for a similar overhead view). I could also live with a drawing, as long as it's somewhat detailed and lifelike (not a wireframe schematic or a cartoon). Or failing that, maybe someone knows of a 3D model of the bridge where I could manipulate the camera and position it just the way I want? Thanks in advance.
