The Moose River bridge at Mile 142.5, Ontario Northland's longest span as seen from the cab of GP38-2 1806 pulling June 28, 2001's northbound Polar Bear Express. Truly a breathtaking sight. It's not the highest bridge I've ever seen, but as I mentioned, this thing's long. The fact that the train slows to a snail's pace while crossing gives everyone aboard an opportunity to check out the spectacular view.
