The only problem is the the river is so wide I'd need two spans 'back to back'. Not necessarily a bad problem, but I want to shop around and explore the options to find a large single span bridge. I am already using an American Flyer 750 bridge on one loop. I need something similar for the current project.
So we could conceivably have the inner loop done by Christmas or New Year of 2012. It'll be nice to be able to run three trains at once. It still leaves lots to do in terms of finishing off the yards and planning the coal flood loading facility.
