I thought I ought to join in the fray. This rendering is of the Huey P Long Bridge retro-fit in New Orleans. The old (current) configuration has two 10' lanes with no shoulder. Apparently this is now under construction. We (Brian Peterson and myself) ended up doing several renderings and an animation that is up on their site: http://www.timedla.com/bridge/long/overview/
The file started in MR and then we finished it in V-Ray. The steelwork is a primarily opacity maps. I'd love to throw are new car library in this. The old LP3D just don't cut it anymore...
